Installation Best Practice
GETTING ROOFLIGHTS RIGHT
As part of its mission to support best practice, The Rooflight Association highlights the
main points to consider and hazards to be aware of when installing rooflights.
Everyone loves well day-lit interiors, whether
in residential, commercial or industrial
buildings. This is why the popularity of
rooflights is growing in every sector. Rooflights
deliver up to three times more light than the same
area of vertical glazing, transforming spaces,
creating healthy environments and adding value
to property.
In recent years, increasing demand has driven
an explosion in the number of different types
of rooflight available. It’s also resulted in
frequent updates to standards and legislation,
more complex specification decisions, and the
requirement for specialist knowledge at every
stage of the supply chain.
This is where The Rooflight Association comes
in. Comprising most of the UK’s leading rooflight
manufacturers, as well as contractors, consultants
and other roof- and rooflight-related organisations,
we are the UK trade association representing
all aspects of rooflighting. Our mission is to
support best practice and to ensure growth and
sustainability in all sectors of our industry.
So what makes a successful rooflight installation?
There are several factors to consider:
The amount and type of light required
This is largely governed by the use of the
building in which rooflights are to be installed.
For example, a workshop or studio in which
precise detailed work is carried out will benefit
from a higher light level than say, a warehouse
interior. For most applications, diffused daylight
is preferential for a more even distribution of
light without harsh shadows or glare. This has a
bearing on the glazing material to be specified.
Thermal performance & energy efficiency
The Building Regulations for the four devolved
nations of the UK each stipulate limiting U-values
for rooflights and roof windows, as part of the
government’s commitment to achieving net zero.
As a rule, even regs-compliant rooflights are
usually less well insulated than the surrounding
The Rooflight Association welcomes membership from
contractors, manufacturers, specifiers, consultants and
other parties serving all sectors of the rooflight industry
areas of the roof, but this has little effect on the
total energy required for heating, as the beneficial
effects of passive solar gain compensate for the
poorer insulation. Rooflights will also reduce the
requirement for artificial lighting, creating further
significant energy savings.
To ensure compliance with the relevant
regulations, it’s important to be aware of the
required U-values for specific applications. The
Rooflight Association has published a series
of ‘Quickguides’ covering this topic in respect
of each of the four UK nations. These can be
downloaded at:
rooflightassociation.org/energy-saving/
Control of internal temperatures
Rooflight areas have a bearing on internal
temperatures and a wide range of solar control
options are available for rooflights, including solar
control glass and blinds. Building orientation can
also affect solar heat gain, so cases should be
viewed on an individual basis.
In many applications, rooflights can be configured
to provide ventilation as a further benefit to internal
environments and a means to control internal
temperatures, to comply with the relevant national
Building Regulations in respect of overheating.
Safety for roof workers and occupants
Safety is a key consideration for any rooflight
installation. The incidences of fatalities or injuries
caused by falls from height on building sites have
reduced in recent years, thanks to the sustained
efforts of organisations like The Rooflight
Association, HSE (The Health & safety Executive),
ACR (Advisory Committee for Roofsafety and
FASET (Fall Arrest Safety Equipment Training).
However, there is no room for complacency.
Guidance is available at:
rooflightassociation.org/safety-on-roofs/
Safety for building occupants is also a key
consideration. Shattering of inner panes can
result in building occupants being exposed to
danger from falling glass. To eliminate this risk,
ensure your rooflight supplier confirms the use of
laminated glass inner panes – or is able to supply
a detailed risk assessment.
Rooflights are also subject to fire ratings, so it’s
important to be aware of these to ensure safety
and compliance. The Rooflight Association has
published guidance in this respect, available at:
rooflightassociation.org/fire-performance/
It’s also worth noting that Building Regulations
covering security may need to be addressed in
certain applications, particularly in built-up areas
where there is access to roof areas.

Trends
WHY FLAT'S IN FASHION
Rooflight supplier Whitesales highlights the consumer trend for flat rooflights, and
unpacks the reasons behind their rise in popularity...
Interest online, customer enquiries and sales at
daylighting specialist Whitesales all point to the
fact that it’s flat rooflights which are currently
setting the trend in the rooflights market. The
company has even put a catwalk built entirely of
flat rooflights at the centre of its new ‘Flat’s in
Fashion’ marketing campaign to emphasise the
shift they are seeing amongst consumers towards
the sleek and contemporary flat rooflight, and away
from the more traditional looking roof lantern.
A flat rooflight gives a property a
‘minimalist, contemporary’ look
Figures from the Whitesales website reveal a
133% rise in the number of views of its em.glaze
flat rooflight range over the past 12 months, and
sales enquiries are currently running at 80/20 in
favour of flat rooflights over lanterns.
Sioned Yates, Whitesales’ Marketing Director,
says it’s largely younger and more affluent
customers who are expressing a preference for
the clean lines and sleek finish of the em.glaze
products: “We’ve seen in the latest round of
consumer research from Keystone that younger
consumers are more likely to want glazing in the
roof, and these seem to be the people driving the
current trend.
“No home makeover show or home improvement
magazine is complete at the moment without the
inclusion of a flat rooflight, and that’s obviously great
news for anyone selling or installing our products.”
Karl Grandfield, Whitesales’ Sales Manager, adds:
“This is a trend which has actually been building
for the past four of our five years in the premium
end of the market, and now we’re seeing it filtering
down to the mainstream as well. A flat rooflight
gives a property a minimalist, contemporary look
which lots of buyers love. And there’s the big
advantage of course that a flat rooflight doesn’t
interfere with the view from bedrooms above –
and that’s definitely a factor for buyers in smaller
homes.”
Whitesales’ customer Will Bull, from Rooflights
and Atriums, agrees that demand is increasing for
flat glass: “Whilst contemporary roof lanterns still
remain a popular choice in some applications,
Rooflights & Atriums have seen increased
demand in 2024 for flat glass from people
wanting a more modern feel for their space. Flat
glass generally offers more choice with glass
specification, options to suit all budgets, better
security and the potential to captivate the popular
architectural vision of having huge single panes
of glass. The ‘flat glass’ solution remains as
popular as ever.”
Sioned adds: “If you need any more evidence of
the trend, you only have to look at the number
of new suppliers trying to get into the flat roof
market. When companies who have made their
name manufacturing lanterns start developing
and marketing flat rooflights, you know that flat’s
definitely in fashion.”
Karl Grandfield is keen to point out that, for
installers, flat rooflights are actually an easier
and lower risk proposition than lanterns. He
explains: “Products like our em.glaze flat glass
rooflights are supplied pre-glazed, so there’s no
on site assembly required. All that fitters have to
do is fix the rooflight to the upstand – which we
can also supply. And there’s no chance that they
will leak because there are three separate barrier
methods in the glazed section, which means no
costly remedials.”
Whitesales is helping customers make the most
of the trend towards flat rooflights with the launch
of its em.glaze Economy rooflight alongside the
existing em.glaze Premium. The Economy version,
which can actually work out cheaper than the
equivalent sized lantern, features CWCT Class
3 glazing rather than the walk-on CWCT Class 1
glass in Premium, and aesthetically the only thing
that distinguishes the two options is that the
Economy is non-fritted.
The em.glaze rooflight range is available in a variety
of ventilation and glazing options and up to 18 stock
sizes delivered to site in just three-five days, backed
by the full Whitesales sales and service package.

Contract Roof Lanterns Talk
THE SHEER BREADTH OF OPTIONS
Jon Crohill, Project Manager (Design), tells Total Rooflights+ about the technical
developments and updates that have taken Sheerline’s already hugely popular S1 Roof
Lantern to the next level...
When Sheerline first launched its S1
Roof Lantern in the summer of 2021,
the company knew it was going to be
popular because it was designed by the expert
in-house R&D team to be ultra-secure, energy
efficient, stylish, and thoroughly modern.
Over the past three years, the S1 has become
a firm favourite of homeowners and industry
professionals alike. In 2022, it was named ‘Best
Technical Innovation’ at the GGP Installer Awards
and achieved Secured by Design accreditation
later the same year.
So how has Sheerline made this award-winning
(and popular) product even better? And why now?
Sheerline’s Project Manager (Design) Jon Crohill
explains the how and why below...
SheerVent closed
SheerVent open
Above: Jon Crohill, Sheerline’s Project Manager (Design). S1 Roof Lantern with the SheerVent intelligent ventilation system.
Award-winning features for an awardwinning
product:
“Designing the S1 from scratch provided a unique
opportunity to create a product that was not only
exceptionally beautiful but also tackled some of
the long-standing issues with roof lanterns. We
knew we wanted to create a next gen aluminium
product that would raise the bar for high quality,
aluminium lanterns and give the end user a
genuinely better product in every regard. So, here
are just some of the key features that enabled S1
to become the transformative product it has.
“It offers a contemporary, refined design, with
rafter top caps that sit as low down as possible to
the glazing. Alongside end caps that run flush to
the perimeter of the eaves beam, this really sets
S1 apart. Once you’ve seen one of Sheerline’s
aluminium lanterns in the flesh, other lanterns look
slightly crude and old fashioned. For the discerning
homeowner with security in mind, the S1 is also
ideal as it is one of the UK’s most secure lanterns,
with a SBD option available, offering extra peace of
mind. Other in-built security features include anti-
“We’re confident roof
lanterns will continue
to grow in popularity as
homeowners continue
to embrace a bright,
airy aesthetic”
tamper screws, enclosed anti-tamper glass, and
security tape fitted as standard.
“Finally, Sheerline’s Thermlock technology
ensures living spaces stay warm during winter
and cool during summer. With 28mm glazing
and a fully thermally broken design, S1 is unlike
competitor products whose designs usually
include some aluminium elements that bridge
from inside to outside. In terms of choice, nine
standard colour options are available plus
bespoke colours and finishes, there are 13 main
S1 configurations, and LED lighting can be added
around the perimeter and ridge easily via a
purpose designed lighting channel.”
With an impressive list of features, how
has Sheerline improved the S1?
“Two key updates have been made over the past
year to increase the appeal and versatility of this
exceptional aluminium roof lantern. Sheerline’s
3 Way Option has not only added three more
styles to the S1 roof, but it also allows for bigger
spans without jack rafters, giving fabricators and
installers more options when they specify a roof
lantern design.
“But perhaps the biggest change is the addition
of SheerVent, the company’s intelligent ventilation
system. Ventilation in roof lanterns might not be
new, but SheerVent is revolutionary because it
offers a sleek, minimalist design that sits flush
with the rafter bars of the S1. No other vent looks
as integral to the overall design of the lantern,
and none come close to looking so sleek and
refined.
“The design also eliminates the need for muntin
bars, offering reliability without the risk of leaks.
In addition, SheerVent is fully thermally broken
as you’d expect, offering unprecedented levels
8 T R + SUMMER 2024
A FOCUS ON DAYLIGHTING SOLUTIONS FOR THE BUILT ENVIRONMENT

The S1 Roof Lantern has been updated with the 3 Way Option which allows for bigger spans without jack rafters, and the SheerVent system
of thermal efficiency, and uses the same highperformance
28mm glazing as the rest of the S1
lantern.”
Why SheerVent, and why now?
“One of the big differentiators between Sheerline
and other aluminium systems is the drive to offer
consumers choice without compromise. Think:
style, security, sustainability, coupled to a highquality
finish. It’s something the R&D team strive
to achieve in every single Sheerline product, and
SheerVent is no different.
“Aside from being quick and easy to install,
SheerVent solves the challenge of ventilation and
overheating which can occur when you add a
lantern to a room. Many people are familiar with
Part L specifications (energy efficiency), but less
so with Part O (overheating). Part O reflects the
increase in unpredictable and extreme weather,
and will become increasingly relevant in the UK.
“And while energy efficiency of properties has
broadly improved, the potential for overheating in
certain areas must be addressed. SheerVent is
“Aside from being
quick and easy to
install, SheerVent
solves the challenge
of ventilation and
overheating which can
occur when you add a
lantern to a room”
the ideal, elegant solution to overheating when a
lantern is installed, and it offers unique features
designed to complement the S1. For instance,
customers can add discreet sensors for wind, rain,
and light to drive the opener’s powered actuators.”
Final thoughts…
“No one can predict the future, but we’re
confident roof lanterns will continue to grow in
popularity as homeowners continue to embrace
a bright, airy aesthetic that enables them to not
only transform their living space but also better
connect with nature by flooding their homes with
natural light.
“In addition, ventilation is going to gain traction
as a hot topic in line with the UK’s increasingly
hot summers. This will lead developers, builders,
installers, and homeowners to proven solutions
such as SheerVent – solutions that have the
potential to transform a living space and make it
more comfortable during intense heatwaves.
“Installers ready to wow their customers with a
next gen roof lantern and intelligent ventilation
system are invited to contact the Sheerline team
directly on 01332 978000 or email

Roof Lanterns
A FOCUS ON ALUMINIUM SOLUTIONS
Tim Douglas, Technical Manager at Guardian Building Systems, discusses the properties
that make aluminium a great choice to frame roof lanterns.
Roof lanterns are a popular choice for
homeowners who are either adding an
extension to their home or upgrading an
existing flat roofed space. They not only bring
additional light into a room but, by increasing
the ceiling height, can also make spaces feel
much bigger and more welcoming. To support
this growing market, new aluminium-framed roof
lanterns are now available which can provide a
range of benefits over older PVC-U alternatives.
These include improved thermal performance, a
sleeker aesthetic, and a range of features which
can support faster, simpler installations.
Why aluminium?
Aluminium has a number of properties that make
it a great choice for the frames of roof lanterns.
The metal is both lightweight and strong. This
means it can be used to create roof lantern units
which can span up to 3m in length but have
a profiled frame width as thin as 12mm. The
result is a clean aesthetic which provides a more
modern, premium look than the more substantial
frames common on older PVC-U units. The ultrathin
frame can also help bring more natural light
into the finished space and provide homeowners
with a better view of the night sky.
Unlike PVC-U units, which can yellow over time
as a result of UV-degradation, aluminium-framed
roof lanterns can be finished with coatings which
will retain their original colour better over time.
The metal is also suitable for powder-coating,
allowing a seamless finish in a range of colours to
your customer’s preferences.
Modern aluminium framed units can typically
be supplied with double or triple glazed units
depending on the homeowner’s priorities. In
general, noise dampened double glazed units
offer the most effective solution if they’re looking
to minimise outside noise from busy roads, low
flying planes, or other sources. Triple glazed units,
meanwhile, can provide an especially effective
barrier to heat losses, achieving U-values as low
as 1.0 W.m 2 K.
Alongside the glazing, the frame itself can also
account for a significant proportion of heat
loss from a roof lantern. For this reason, some
advanced solutions feature specially profiled
aluminium components which create a thermal
break in the frame. This cuts the path for heat
to pass through the lantern and, in combination
with the glazing, can mean the units effectively
limit both unwanted heat loss and draughts –
reassuring any customers worried about rises to
their heating costs.
Flexible and easy to install
Modern aluminium framed roof lanterns can also
help to speed up and simplify installations.
The lightweight frame helps to limit the structural
loading on the roof deck. This can make it a
viable option for some existing flat roofs with
little or no additional supports depending on the
loading capacity. It also makes manual lifting and
positioning much simpler on site, helping you to
get on with the installation.
Some manufacturers can produce and supply the
roof lantern kits to the specific dimensions you need
The Guardian Roof Lantern features a
lightweight aluminium frame, delivering a
high-quality aesthetic, whilst its ‘click-fit’
rafter system allows rapid installations
for your project. The machine-finished components
can be rapidly assembled and typically include
less parts than off-the-shelf alternatives.
The latest roof lantern models can also incorporate
a number of features which can provide added
security whilst further streamlining installations.
These include tamper-proof fixings and ‘clickfit’
mechanisms which can be easily fitted but
are very difficult to remove. The combination of
these features means these advanced aluminium
framed roof lantern units can often be constructed
in less than 60 minutes, allowing for quick and
easy installations which can be achieved in even
changeable weather conditions.
Roof raising results
Roof lanterns can provide the perfect finishing
touch for any flat-roofed home extension. By
taking advantage of the latest aluminium framed
solutions, installers can reduce installation time
and complexity, delivering tailored roof lanterns
which provide excellent thermal performance and
will continue to look the part for years to come.

Rooflights
ALL OPTIONS COVERED!
The team at LAMILUX UK discuss their extensive daylighting offering and technical
support, which helps installers achieve outstanding efficiency, easy installation, and
compliance with the latest regulations…
When specifying rooflights and glass
roofs, there are many factors to
consider, and the practical side of
installation is often overlooked during the
initial design stages. LAMILUX not only offer
an aesthetic portfolio of thermally broken
daylighting products with outstanding energy
efficiency, including Passivhaus certified,
but also assure compliance and practicality
from the design process, right through
to installation on site, to help you avoid
common pitfalls further down the line.
Modular rooflights for flat roofs
Rooflight upstands are often built on site
and as stated in Approved Document L,
now must meet a U-value of 0.35 W/m²K
or lower. However,
some suppliers such
as LAMILUX have
a range of modular
rooflights available
with insulated GRP
upstands, which are
pre-assembled at
the factory during the
production process.
If the upstand is
formed as part of the rooflight, the combined
performance of the rooflight and upstand can be
used, with a maximum requirement of 2.2 W/m²K
to meet building regulations.
By selecting a conforming rooflight with the
upstand pre-assembled, this not only ensures

boasts an improved thermal performance, with

Minimizing the risk of errors with a guaranteed
perfect fit and superior thermal performance, a
rooflight with an integrated GRP upstand also
LAMILUX offer a range of modular rooflights with insulated GRP upstands
which are pre-assembled at the factory during the production process
makes installation
quick and simple
whilst saving
costs and time
constructing
timber upstands
on site. This can
be particularly
beneficial when using circular rooflights, where
curved timber upstands are renowned for being
difficult to construct.
The LAMILUX GRP heat-insulated upstand also has
a seamless silk-white interior finish which removes
the need for internal plastering. LAMILUX upstands
are available for the LAMILUX range of circular,
square, pyramid and rectangular skylights in a
wide range of standard sizes, and are available in
heights of 150mm, 300mm, 400mm, 500mm and
700mm, which means there is always a solution
to achieve the required 150mm height above the
finished roof level according to BS 6229:2018,
even if using a thicker external insulation.
Pitched versions are also available.
Furthermore, the LAMILUX range of glass and
polycarbonate skylights undisputably achieve
the mandatory U-values.
Mono-pitch rooflights
For larger glazed areas, mono-pitch rooflight
solutions such as the LAMILUX Glass
Skylight MS78, which is a self-aligning
system, simplifies installation, thus saving
time and on-site costs. Such mono-pitched
rooflight systems are designed with an easy,
fast and uncomplicated process in mind,
from selection to installation, presenting
design flexibility within a product that is easy
to both specify and install.
The Glass Skylight MS78 is configured
by forming a row of pre-fabricated fixed
or opening modules, that are installed in a
standardized manner from left to right to produce
a bespoke mono-pitch rooflight to suit most
projects. With attachment of the self-aligning
module connection via the V-groove, a simple,
quick and safe assembly can be achieved to give
optimal connection to the roof, eliminating the
need for time-consuming, and costly installation
processes.

SHEERVENT DELIVERS '21 ST CENTURY AUTOMATION '
Prefix Systems recently launched the ‘revolutionary’ new SheerVent
for the S2 glazed roofing system.
With more experience than most in first generation roof vents, Prefix
says this new innovation from Sheerline is a ‘game-changer’ for the
glazed roof market, bringing an integrated solution that doesn’t suffer
from water ingress thanks to an integrated muntin bar with installation
directly into the ridge baffle.
Prefix says S2 is re-defining the way in which glazed extensions look
and perform, and now the dedicated SheerVent solution provides carefree
long-term performance benefits and has been designed to seamlessly
integrate with the S2 roofing system.
With slimline sightlines, SheerVent sits lower down than the traditional,
‘clumsy looking’ first generation roof vents, and is available in sizes up to
1.1 wide x 1.2m high.
This new solution is fully thermally broken with 24mm glazing as
standard, and brings to market ‘accessible 21st century automation’
through light, wind and rain sensors for comfort and lifestyle benefits.
Chris Cooke, director of Prefix Systems said: “The glazed and
conservatory roof sectors have been plagued with poorly performing roof
vents for decades. With the S2 SheerVent, we’re now able to offer our
customers a next generation product that performs as well as it looks.
“The whole S2 glazed roofing system is already generating rave reviews
from installation companies across the UK, and this addition to the range
will further support this view as we look to offer best in class solutions
across glazed roofs, our award-winning WARMroof and through our
outdoor living solutions, including Verandah.”

'TESTIMONIALS DON'T GET MUCH BETTER THAN THAT'
“We always loved the house, but hated the kitchen and how dark
and small it was. Now, we honestly love it. It’s bright and spacious
and our favourite part of the house. Our electrician added some LED
lights around the rooflights, so even at night they’re still the focus of
the room.”
Testimonials don’t get much better than that from a couple in Surrey
who had two Whitesales’ em.glaze flat glass Premium rooflights installed
in a new ground floor extension in their early 20th century end of terrace
property.
Their 5.5m wide x 4m deep extension replaced an old utility room on the
back of the house, transforming the kitchen into a light and airy space,
complete with rooflights, bi-fold doors and a living green roof.
The Whitesales em.glaze rooflights were specified by the couple’s
architect, One World Design, in response to their brief which was to bring
as much as light as possible into the north facing rear of the house.
The couple added: “The kitchen and the garden face north, so previously
the rear of the house was always gloomy, and this affected the whole
of the ground floor. We were chatting to one of our neighbours about the
build and they said they had decided against doing the same thing a few
years ago because they thought the finished result would be too dark.
Now that they have seen how good our kitchen looks, they have just
signed off their plans ready to build something very similar.”
The whole extension was completed over a four month period, with
Whitesales supplying the em.glaze rooflights direct to site for installation
by builders Heronlake Construction. The living roof, which has since
become a haven for bees, was added after the rooflights by the
specialists at Green Roofing.
Flat glass rooflights are currently outstripping conventional glass lanterns
in terms of enquiries into Whitesales, with the streamlined look and ease of
installation proving popular with homeowners and builders alike.

ROOFLIGHT SAFETY NETS: BEWARE OF THE DANGERS!
A new safety bulletin outlining the potential risks of using rooflight
safety nets has been jointly published by The Rooflight Association and
FASET, the Fall Arrest Safety Equipment Training association.
Safety netting has played an important role in the construction industry
for many years. Usage of nets conforming to BS EN 1263-1 in underslung
applications is supported by FASET as well as HSE (Health & Safety
Executive) and ACR (Advisory Committee for Roofsafety).
However, more recently, The Rooflight Association has expressed concern
regarding netting products which are being offered for use over rooflights
as a means of fall arrest in the event of a person falling onto a rooflight
which may be classed as ‘fragile roof’. Some manufacturers’ installation
instructions show nets being secured over out-of-plane rooflights by means
of a ratchet strap to the upstand, or freestanding unfixed and unsecured
temporary framework.
Mark Wilcox, Safety Representative for The Rooflight Association, said:
“These practices are potentially a danger to life. Typical rooflight upstands
are not designed, tested or attached to the roof in such way as to be able to
provide reliable anchorage for a safety net or safety line of any kind.”
The bulletin, entitled Rooflight Safety Nets: be aware of limitations and
potential dangers, can be downloaded free of charge from:

BESPOKE ROOF WINDOWS FOR LANDMARK HOTEL
Keylite Roof Windows (Keylite) aided with the major restoration
of the five-star luxury Conservatorium hotel in Amsterdam,
Netherlands, by providing 263 non-standard conservation roof
windows in bespoke sizes.
Adjacent to some of Amsterdam’s cultural hotspots, the Conservatorium
hotel began as a former bank and soon after a music school. Now,
it stands proud as one of the most beautifully designed hotels in
Amsterdam, boasting 129 rooms and suites, six meeting and event
venues, and a luxury wellness centre. Sympathetically restored by
award-winning Milan-based designer and architect Piero Lissoni, this
spectacular building fuses simplicity and functionality, with contemporary
updates including clean lines and elegant glasswork.
The high-profile restoration of this historic Amsterdam building into
a luxury hotel required Keylite to work in close collaboration with the
constructor, Structon, to manufacture and supply 263 specially designed
roof window units in completely non-standard sizes ranging from
660 x 1500mm to 780 x 2000mm.
Mike Ensing, National Manager at Keylite Holland, said: “The
Conservatorium is truly a fantastic hotel in the heart of Amsterdam.
Originally a bank, the space at the top of the original building was closed
and dark, and Lissoni’s vision was to allow natural light and fresh air in
through large windows.
“Being a national monument, the strict legislation regarding the
building’s historical nature meant that disrupting the structural body,
beams and brickwork was out of the question. Carefully curated windows,
fully approved by Monument Care, were the only solution to achieve
Lissoni’s biophilic design of bringing the outdoors in.
“As a conservation building, special monument glass was required for
each of the Keylite roof windows, which was shipped from Holland to
the Keylite factory in Poland and then cut to non-standard sizes. It was
clear that Keylite was specified for this project because we could deliver
something tailor-made that other manufacturers couldn’t fulfil.”

RETAINING THE ESSENCE OF HISTORY
When Hatchards, the oldest bookshop in London, required a new bespoke rooflight, the
British institution was in safe hands with Chrisalis Refurb and Howells Patent Glazing...
Occupying 187 Piccadilly, Hatchards is the
oldest bookshop in London. Established by
publisher and anti-slavery campaigner, John
Hatchard in 1797, it boasts three Royal Warrants.
The bookseller, now owned by Waterstones,
exclaims that the ‘essence of 187 Piccadilly
remains the same and is unchangeable’. This
presented quite a challenge for contractor,
Chrisalis Refurb, when tasked with supplying
and installing external scaffold access to the
front elevation up to roof level incorporating a
temporary roof, giving access to remove the
existing rooflight, make good areas of the existing
opening and then to supply and install a new
bespoke rooflight.
For the glazing solution, Chrisalis Refurb sought
the expertise of Howells Patent Glazing.
Replica rooflight
187 Piccadilly is a listed building, therefore the
rooflight had to be replaced like for like.
Originally the rooflight would have been single
glazed with lead. Over the years it has been
updated and Howells was tasked with replacing
the Georgian wired cast glass which had been insitu
for 20-30 years.
The rooflight sits above office space with a
suspended ceiling and this was factored into the
specification.
Draughtsman Warren Lowe attended site for an
initial survey. This proved particularly challenging
due to the position of the rooflight, the roof
structure and details.
Survey and specification
“The Georgian wired cast glass is not classed as
a safety glass nowadays so had to be replaced,
plus it was starting to slip and leak,” said Warren.
“We recommended a replica polycarbonate
to meet the requirement for a single glazed
Above, Hatchards bookshop at 187 Piccadilly. Top right, the rooflight installation in progress, and bottom right, complete
option. We suggested this because it is
lightweight so wouldn’t add extra load to the steel
support frame, and it is not translucent so it is
aesthetically more pleasing given the view of the
suspended ceiling beneath.”
For the structure of the rooflight, Howells selected
its HG3 bar. While the internal stalk would be
covered by the suspended ceiling below, the
external wing bar is visible and a good match for
the original, as is the bar’s uncoated mill finish
which will dull-down overtime.
Once the scaffold had been erected, Howells
carried out a full survey and produced drawings
for client approval, and later manufacturing.
These drawings were also used by the client to
gain approval from Building Control.
Overcoming the challenging location
Piccadilly is an extremely busy thoroughfare in
central London, so this and the rooflight being five
storeys up meant the removal and installation of
the rooflight had to be meticulously managed.
A pre-start meeting was held on-site with Chrisalis
Refurb, the scaffold company and Howells, to
agree the lifts of the scaffolding; where the scaffold
loading area and hoist would be situated to enable
the existing rooflight to be removed, broken into
sections and then disposed, and the delivery and
installation of the new rooflight.
The removal and delivery were carried out at
weekends to minimise disruption. The new
aluminium rooflight was delivered in sections and
hoisted up to roof level ready for installation. The
existing steel support frame for the rooflight was
made good prior to the installation of the new
aluminium replica rooflight by Howells’ fitting
team. The entire process was carried out inside
a scaffold tent to prevent rain ingress and stop
falling debris.
Professional and reliable
Commenting on the working relationship with
Howells, Chrisalis Refurb, said: “We found them
[Howells] to be very professional and reliable
from the initial planning stages with Walter
Howells, through to getting drawings approved
with Warren Lowe.”
