Introduction<br />
Flat Roofs<br />
Over the past few years, there have been<br />
major advances <strong>and</strong> improvements in the<br />
materials used in modern roofing<br />
technology. The specifier now has<br />
renewed confidence to take full<br />
advantage of the benefits of a <strong>flat</strong> roof<br />
<strong>and</strong> low pitched roof design concept.<br />
Flat <strong>roofs</strong> allow greater planning <strong>and</strong><br />
design flexibility - roof-top gardens,<br />
terracing, patios, car parks, building<br />
services <strong>and</strong> ventilation equipment,<br />
delivery areas <strong>and</strong> provision <strong>for</strong> adding<br />
additional storeys at a later date. All can<br />
be accommodated in a <strong>flat</strong> roof design.<br />
Extensive or irregular shaped buildings<br />
can be roofed more quickly, easily <strong>and</strong><br />
cost effectively than a pitched roof.<br />
Internal condensation is less of a risk<br />
because a <strong>flat</strong> roof uses less airspace<br />
than a pitched roof. In addition, the need<br />
to heat <strong>and</strong> illuminate voids is eliminated.<br />
Flat <strong>roofs</strong> allow easy access to natural<br />
light <strong>and</strong> because of the simple<br />
construction, internal partitioning is easy.<br />
This is especially advantageous <strong>for</strong><br />
commercial or industrial buildings.<br />

The Need <strong>for</strong> Rainwater Outlets<br />
Any <strong>flat</strong> area needs careful design to<br />
ensure efficient removal of surface water.<br />
Traditionally, water from a <strong>flat</strong> roof or<br />
other structure is channelled by way of a<br />
slope to a <strong>rainwater</strong> pipe. Leaks can often<br />
occur at the junction of the membrane<br />
<strong>and</strong> the <strong>rainwater</strong> pipe.<br />
To overcome this potential problem,<br />
ACO <strong>Fulbora</strong> <strong>rainwater</strong> <strong>outlets</strong> provide a<br />
<strong>watertight</strong> joint between the membrane<br />
<strong>and</strong> the outlet by mechanically clamping<br />
the membrane to the sump unit. Tried <strong>and</strong><br />
tested <strong>for</strong> over 40 years, ACO <strong>Fulbora</strong><br />
<strong>outlets</strong> have been used successfully on all<br />
types of <strong>flat</strong> roof construction.<br />

Hydraulic Design Considerations<br />
Overview<br />
The following notes are intended as a<br />
guide to the specifier who is designing a<br />
<strong>rainwater</strong> drainage system <strong>for</strong> a roof. It is<br />
recommended that reference is made to<br />
British St<strong>and</strong>ard BS EN 12056 : 2000<br />
Gravity Drainage Systems Inside<br />
Buildings - Part 3 : Roof drainage, layout<br />
<strong>and</strong> calculation <strong>for</strong> a comprehensive<br />
design guide.<br />
For any <strong>rainwater</strong> drainage system to<br />
work effectively <strong>and</strong> reliably, due account<br />
must be taken of the following<br />
considerations:<br />
■ Geographical location<br />
■ Rainfall intensity<br />
■ Effective catchment area of roof<br />
■ Risk category of building<br />
■ Hydraulic capacity of the drainage<br />
system(s) employed<br />
Geographical Location<br />
Rainfall intensity has a direct impact on<br />
the per<strong>for</strong>mance requirements of any<br />
<strong>rainwater</strong> drainage system. For <strong>roofs</strong> <strong>and</strong><br />
paved areas, it is normally impracticable<br />
to guard against very infrequent,<br />
extremely heavy rainfall situations <strong>and</strong> so<br />
the designer should aim to strike a<br />
balance between the cost of the drainage<br />
system, the risk category of the building<br />
<strong>and</strong> the frequency <strong>and</strong> subsequent<br />
consequences of flooding.<br />
The drainage system <strong>for</strong> <strong>roofs</strong> <strong>and</strong> paved<br />
areas should be capable of coping with<br />
the intense rainfall that accompanies<br />
summer thunderstorms.<br />
The UK experiences complex <strong>and</strong> varied<br />
rainfall patterns. For example, surprisingly,<br />
although the upl<strong>and</strong> areas of northern <strong>and</strong><br />
western parts of the British Isles<br />
experience higher average annual rainfall<br />
than the lowl<strong>and</strong> areas, the lowl<strong>and</strong> areas<br />
experience more frequent <strong>and</strong> more<br />
intense short duration rainfall than the<br />
upl<strong>and</strong> areas. British St<strong>and</strong>ard BS EN<br />
12056 : 2000 may be referred to <strong>for</strong><br />
further in<strong>for</strong>mation <strong>and</strong> guidance on this<br />
topic.<br />
A rainfall intensity of 75 mm/hr (0.02 l/s/<br />
m 2 ) is used throughout this design<br />
catalogue.<br />
Flow Rate Calculation<br />
The flow rate Q, from <strong>roofs</strong>, paved areas<br />
<strong>and</strong> vertical walls <strong>and</strong> surfaces is<br />
calculated as follows <strong>and</strong> assumes that all<br />
surfaces are impermeable:<br />
Q = A x I litres/second<br />
3600<br />
where<br />
Q = Volumetric flow rate (l/s)<br />
A = Effective catchment area (m²)<br />
I = Rainfall intensity (75 mm/hr)
Effective Catchment Area of Roofs<br />
Pitched Roofs<br />
The effective catchment area of a freely<br />
exposed pitched roof draining to an eaves<br />
or parapet wall gutter is equal to the plan<br />
area of the roof plus half its maximum<br />
elevation area.<br />
Catchment Area A = (f x l) + (g/2 x l) (m²)<br />
= l(f + g/2) (m²)<br />
All linear dimensions in metres.<br />
Figure Figure Figure Figure Figure 1. 1. 1. 1. 1. Pitched Pitched Pitched Pitched Pitched Roof Roof Roof Roof Roof<br />
Flat Roofs & Paved Areas<br />
For a monopitch <strong>flat</strong> roof or paved area<br />
with a freely exposed horizontal surface,<br />
the effective catchment area is equal to<br />
the plan area of the area to be drained as<br />
shown below:<br />
For a <strong>flat</strong> roof with a dual pitch, split the<br />
roof up into discrete areas to isolate the<br />
catchment areas as follows:<br />

Effective Catchment Area of Roofs<br />
Flat Roofs & Paved Areas with Adjacent Vertical Surfaces<br />
Flat <strong>roofs</strong> or paved areas that are<br />
adjacent to vertical walls <strong>and</strong>/or glazed<br />
surfaces will be subjected to an increased<br />
hydraulic load due to the effects of wind<br />
driven rain against these vertical surfaces<br />
<strong>and</strong> subsequently running off onto the<br />
roof.<br />
For a <strong>flat</strong> roof exposed to a single wall as<br />
shown in Figure 4, assume the effective<br />
catchment area to be half the exposed<br />
vertical area of the wall <strong>and</strong> is shown as<br />
follows:<br />
From Figure 2, Catchment Area B = a x b (m²)<br />
Vertical Wall Catchment Area E = a x H/2 (m²)<br />
Total Catchment Area = (a x b) + (a x H/2) (m²)<br />

Practical Design Tips<br />
When designing an engineered <strong>rainwater</strong><br />
scheme, the following design hints are<br />
suggested:<br />
■ Do not design <strong>for</strong> the maximum outlet<br />
hydraulic capacity, allow a 10% factor<br />
of safety margin <strong>for</strong> intense storms<br />
<strong>and</strong> leaf/debris blockage.<br />
Roof Catchment Area B = a x b (m²)<br />
Similarly, <strong>for</strong> a <strong>flat</strong> roof exposed to two or<br />
more vertical walls <strong>for</strong>ming an angle or<br />
bay, the assumed resulting wind direction<br />
requires that the combined areas of the<br />
walls should be considered together as<br />
follows:<br />
Vertical Wall Catchment Area E = a x H/2 (m²)<br />
Vertical Wall Catchment Area F = b x h/2 (m²)<br />
Total Catchment Area = (a x b) + ½√ (E²+ F² - 2F x Cos θ) (m²)<br />

■ Always allow <strong>for</strong> a back-up outlet,<br />
even though only one outlet may be<br />
required.<br />
■ Rainwater <strong>outlets</strong> should be inspected<br />
<strong>and</strong> cleaned at least every 6 months<br />
to ensure reliable <strong>and</strong> continuous<br />
operation.

Description<br />
The ACO <strong>Fulbora</strong> HP range of <strong>rainwater</strong><br />
<strong>outlets</strong> provides a comprehensive<br />
selection of high per<strong>for</strong>mance <strong>rainwater</strong><br />
outlet solutions <strong>for</strong> most domestic,<br />
industrial <strong>and</strong> commercial applications<br />
involving <strong>flat</strong> <strong>roofs</strong>, balconies <strong>and</strong> terracing.<br />
High Flow Rate<br />
Advanced design features encourage a<br />
higher flow rate of water through the<br />
outlet compared to conventional systems<br />
by reducing the amount of air that is<br />
drawn into the outlet. If allowed to go<br />
unchecked, a vortex will <strong>for</strong>m as the<br />
water enters the outlet - the same effect<br />
can be seen in the bath or a sink when<br />
the plug is removed.<br />
Product Features<br />
■ Cost effective drainage solution - high<br />
flow rates minimises number of<br />
<strong>outlets</strong> required.<br />
■ Secure grating to prevent v<strong>and</strong>alism<br />
<strong>and</strong> theft.<br />
■ Comprehensive product range <strong>for</strong><br />
most applications.<br />
■ Durable, corrosion resistant<br />
construction.<br />
■ Gun-metal optionally available.<br />
At the centre of the vortex, a void is<br />
naturally <strong>for</strong>med as the water spirals<br />
through the outlet. Under these<br />
conditions, both water <strong>and</strong> air are drawn<br />
into the outlet significantly reducing<br />
efficiency. For maximum flow rate<br />
efficiency, only water should enter the<br />
outlet. This may result in the use of fewer<br />
<strong>outlets</strong> <strong>for</strong> a given installation.<br />
The ACO <strong>Fulbora</strong> HP range of <strong>outlets</strong><br />
provide anti-vortex design features to<br />
minimise this effect <strong>and</strong> a twofold design<br />
approach is adopted to achieve this. On<br />
all circular domed gratings an inverted<br />
cup arrangement is integrated within the<br />
grating to breakdown the vortex effect<br />
within the grating <strong>and</strong> in addition, the leaf<br />
guard geometry of the gratings is<br />
optimised to encourage water to flow<br />
radially into the outlet, thereby minimising<br />
the vortex effect outside of the grating.<br />
Reduced Installation Costs<br />
Compared to conventional <strong>outlets</strong>, high<br />
per<strong>for</strong>mance <strong>outlets</strong> mean either fewer<br />
<strong>outlets</strong>/pipe/groundworks with reduced<br />
installation costs, or greater security in<br />
extreme rainfall conditions.<br />
Secure Gratings<br />
All gratings <strong>for</strong> the HP range of products<br />
are secured with stainless steel fixings<br />
that require either a socket wrench or<br />
spanner <strong>for</strong> removal <strong>and</strong> replacement.<br />
This provides additional security to<br />
prevent theft or v<strong>and</strong>alism.
Membrane Clamp<br />
The roof membrane is positively secured<br />
into the outlet body by a clamp <strong>and</strong> is<br />
secured by 2 stainless steel fixings. The<br />
membrane clamp is serrated on the<br />
underside <strong>for</strong> improved membrane clamp<br />
grip per<strong>for</strong>mance. The outlet design<br />
ensures the integrity of the seal between<br />
the clamp <strong>and</strong> body is not disturbed when<br />
the grating is removed <strong>for</strong> maintenance<br />
during the life of the installation.<br />

Vertical screw <strong>outlets</strong> have a female<br />
parallel thread to BS 21 : 1985 <strong>for</strong><br />
connecting directly to tubes con<strong>for</strong>ming<br />
to BS 1387 : 1985 which is supplied with<br />
a taper male thread. This ensures a<br />
completely <strong>watertight</strong> seal when screwed<br />
fully home into the outlet body. A range of<br />
PVC adaptors are available from ACO<br />
<strong>Fulbora</strong> to allow connection to aluminium<br />
pipework, socketed <strong>and</strong> socketless cast<br />
iron pipework <strong>and</strong> PVC pipework.<br />
HP 45° & 90° Spigot Outlets<br />
These angled problem solving units are<br />
particularly relevant to suit more complex<br />
pipe run detail. Pipework connections as<br />
per vertical spigot details.<br />
HP Balcony Spigot Outlet<br />
The balcony outlet provides discrete safe<br />
drainage <strong>for</strong> balconies <strong>and</strong> walkways.<br />
Supplied complete with a D-shaped <strong>flat</strong><br />
grating, the outlet can be installed against<br />
a wall. The grating is supplied with holes<br />
to receive either 50 mm, 75 mm or<br />
100 mm nominal bore <strong>rainwater</strong><br />
downpipes. These are easily cut on site to<br />
suit the application.<br />
HP Two-Way Screw Outlet<br />
The two-way outlet is designed to be used<br />
at the junction of <strong>roofs</strong> <strong>and</strong> parapet walls,<br />
or wherever a horizontal <strong>and</strong> vertical<br />
surface meet. Available to fit pipe sizes of<br />
50 mm, 75 mm <strong>and</strong> 100 mm. This<br />
flexible design of outlet allows either<br />
horizontal or vertical outflow take-off.<br />
Pipework connections as per vertical<br />
screw details.<br />
HP Gully Spigot Outlet<br />
The gully outlet is designed to fit into<br />
valley gutters <strong>and</strong> is supplied with a<br />
vertical spigot outlet <strong>and</strong> dome grating.<br />
Pipework connections as per vertical<br />
spigot details.<br />
HP Refurbishment Outlet<br />
When an existing <strong>flat</strong> roof is being<br />
upgraded, the refurbishment outlet is<br />
designed to fit inside the existing outlet<br />
<strong>and</strong> pipework with minimal disruption<br />
without the need to remove the original<br />
outlet. The aluminium body incorporates a<br />
wide fixing flange to enhance the bond<br />
with roofing membranes <strong>and</strong> does not<br />
suffer the distortion effects during the<br />
application of torched membranes.<br />
Outlets are supplied with a flexible finned<br />
pipe seal ensuring a <strong>watertight</strong><br />
connection to existing pipework. The ease<br />
of use <strong>and</strong> minimal disruption to the<br />
existing <strong>rainwater</strong> system makes this an<br />
extremely cost effective solution when<br />
upgrading <strong>flat</strong> <strong>roofs</strong>.

HP Range Accessories<br />
A wide range of accessories is available<br />
<strong>for</strong> the ACO <strong>Fulbora</strong> HP range of<br />
<strong>rainwater</strong> <strong>outlets</strong> allowing easy installation<br />
in common <strong>and</strong> not so common<br />
applications of roof construction,<br />
including warm <strong>and</strong> inverted <strong>roofs</strong>,<br />
terraces <strong>and</strong> concealed <strong>outlets</strong> under<br />
raised paving slabs.<br />
Raising Rings<br />
Raising rings are used where it is<br />
necessary to raise the level of the dome<br />
grating above the outlet body, <strong>for</strong><br />
example an inverted roof construction.<br />
With the exception of the Balcony Outlets<br />
(HP-BO) <strong>and</strong> Gully Outlets (HP-GO), raising<br />
rings will only accept dome gratings or<br />
Terrace Grates as the raising rings will<br />
not accept the st<strong>and</strong>ard <strong>flat</strong> grates.<br />
Raising rings are easily cut with a<br />
hacksaw on site if required to match<br />
installation requirements, i.e. to suit<br />
paving slabs. Stainless steel extension<br />
fixings are supplied with each raising ring.<br />
Raising rings are also available <strong>for</strong><br />
Balcony Outlets <strong>and</strong> Gully Outlets. All<br />
raising rings are manufactured from LM6<br />
aluminium alloy to BS 1490 <strong>and</strong> are<br />
optionally available in gun metal to<br />
BS 1400. Suffix sales code with ‘GM’ <strong>for</strong><br />
this option.<br />
PVC Adaptors<br />
PVC adaptors are available <strong>for</strong> threaded<br />
<strong>outlets</strong> - HP Vertical Screw (HP-TD); <strong>and</strong><br />
HP Two-Way (HP-2W) systems. PVC<br />
adaptors provide a quick <strong>and</strong> convenient<br />
connection to st<strong>and</strong>ard PVC pipework.<br />
The adaptors are suitable <strong>for</strong> connection<br />
to all types of pipe systems including cast<br />
iron socketed or socketless systems <strong>and</strong><br />
are assembled using PTFE tape to ensure<br />
a <strong>watertight</strong> connection. Manufactured<br />
from tough PVC-u, the adaptors are<br />
supplied with a male thread <strong>and</strong><br />
chamfered spigot <strong>for</strong> easy connection to<br />
PVC pipes. PVC adaptors are suitable <strong>for</strong><br />
direct connection to:<br />
■ Cast Iron pipework to BS 416:1973<br />
or EN 877.<br />
■ PVC O-ring socketed pipe to<br />
BS 4514:1983.<br />
Deck Supports<br />
Deck supports are used where ACO<br />
<strong>Fulbora</strong> HP <strong>rainwater</strong> <strong>outlets</strong> are installed<br />
in metal deck roof constructions, providing<br />
a stable <strong>and</strong> secure interface between the<br />
outlet <strong>and</strong> roof. Deck Supports are<br />
manufactured from 1.5 mm steel sheet<br />
<strong>and</strong> finished primed in a red oxide paint<br />
finish. Suitable <strong>for</strong> all types of metal deck<br />
roofing.<br />
Terrace Grates<br />
Terrace grates are designed <strong>for</strong> installations<br />
with terraced paving slabs or block<br />
paviors. Terrace grates can only be used<br />
with circular raising rings as described<br />
above. A slotted fixing detail allows 90°<br />
rotational movement to accommodate<br />
slab/pavior patterns.

Description<br />
The ACO <strong>Fulbora</strong> FreeDeck linear deck<br />
drainage system is ideal <strong>for</strong> efficient,<br />
practical solutions to above ground<br />
drainage applications involving block<br />
pavior, paving slab, shingle <strong>and</strong> washed<br />
ballast surface finishes <strong>for</strong> <strong>flat</strong> roof<br />
terraces, decks, balconies, patios <strong>and</strong><br />
roof gardens.<br />
For the effective catchment of <strong>rainwater</strong><br />
run-off <strong>and</strong> the management of<br />
percolation within building substrates.<br />
Rainwater penetrating the deck via paving<br />
slabs, block paviors or granular finishes<br />
are intercepted by the ACO <strong>Fulbora</strong><br />
FreeDeck channel system which<br />
effectively conducts surface water to<br />
accessible outlet positions.<br />
ACO <strong>Fulbora</strong> FreeDeck channels are<br />
simply located directly on top of the water<br />
proofing layer <strong>and</strong> are laid to level invert.<br />
In addition to surface run-off, percolating<br />
water is able to enter the slotted<br />
sidewalls of the channel system <strong>and</strong> track<br />
through concealed ducts to <strong>rainwater</strong><br />
outlet positions. Rainwater <strong>outlets</strong> are top<br />
accessible by means of finish level<br />
meshed gratings <strong>for</strong>med around the<br />
outlet positions.<br />
Either slotted or mesh gratings are<br />
available depending upon positioning of<br />
the channels <strong>and</strong> the nature of the foot<br />
traffic in the areas to be drained. For<br />
example in front of doorways, at the top<br />
of stairways or as perimeter drainage<br />
against parapet walls.<br />

Appendix 1 Material Selection<br />
Overview<br />
This section includes a brief insight into<br />
the materials that the <strong>rainwater</strong> drainage<br />
products featured in this Product<br />
Catalogue <strong>and</strong> Design Guide are<br />
manufactured from.<br />
In certain applications, it is vital to<br />
underst<strong>and</strong> the long term operational<br />
effects that will occur if products are not<br />
specified accurately or installed correctly.<br />
Aluminium Alloys<br />
Aluminium alloys are very common <strong>and</strong><br />
can be found in a wide range of<br />
applications ranging from cooking utensils<br />
to spacecraft. The material is<br />
commercially available in excess of 99%<br />
purity <strong>and</strong> is used primarily <strong>for</strong> its high<br />
resistance to corrosion, lightness <strong>and</strong><br />
strength.<br />
Comparing similar products, aluminium<br />
alloys weigh around one-third as much as<br />
equivalent mild steel <strong>and</strong> stainless steel<br />
products <strong>and</strong> compared to mild steel,<br />
they have a much better corrosion<br />
resistance to atmospheric conditions.<br />
Because aluminium alloys are strong,<br />
lightweight, have good corrosion<br />
resistance, are cost effective <strong>and</strong> have<br />
excellent casting properties, this material<br />
is an obvious first choice <strong>for</strong> <strong>rainwater</strong><br />
<strong>outlets</strong> <strong>and</strong> floor gullies. Additionally,<br />
being non-magnetic, aluminium will not<br />
attract ferrous particles that could<br />
otherwise cause silt traps <strong>and</strong> long term<br />
maintenance issues.<br />
ACO <strong>Fulbora</strong> aluminium <strong>rainwater</strong> <strong>outlets</strong>,<br />
shower drains <strong>and</strong> floor drains use LM6<br />
grade aluminium alloy to BS 1490. LM6<br />
exhibits excellent resistance to corrosion<br />
in both atmospheric <strong>and</strong> marine<br />
environments compared to other<br />
aluminium alloys, <strong>and</strong> is resistant to<br />
sulphate attack <strong>for</strong> curing concrete.<br />
When exposed to the atmosphere, a thin<br />
invisible aluminium oxide film <strong>for</strong>ms on the<br />
surface of the material that protects the<br />
material from further oxidation.<br />
Gun-metal<br />
Gun metal possesses good tensile<br />
strength <strong>and</strong> corrosion resistant<br />
properties <strong>and</strong> is used in many bearing<br />
<strong>and</strong> marine applications. ACO <strong>Fulbora</strong><br />
<strong>rainwater</strong> <strong>outlets</strong> are available in gunmetal<br />
when bi-metallic corrosion<br />
resistance arising from lead or copper<br />
materials is a potential risk.<br />
Gun-metal is an alloy of copper, tin <strong>and</strong><br />
zinc. Admiralty gun-metal typically has a<br />
composition of 88% copper, 10% tin <strong>and</strong><br />
2% zinc.<br />
Galvanised Mild Steel<br />
Mild steel is a convenient, ductile, easily<br />
worked <strong>and</strong> cost effective material that<br />
finds many uses in everyday applications<br />
around us.<br />
In its raw state, mild steel offers no<br />
resistance to corrosion <strong>and</strong> quickly <strong>for</strong>ms<br />
a familiar rust (ferric oxide) on its surface<br />
unless precautions are taken to prevent<br />
oxidation taking place.<br />
Galvanising is a process that is commonly<br />
used to prevent corrosion <strong>and</strong> essentially<br />
consists of a layer of zinc applied to the<br />
surface of the steel. ACO <strong>Fulbora</strong> use a<br />
‘hot dip’ process of dipping the<br />
component into a vat of molten zinc.<br />
Galvanic Corrosion<br />
Galvanic corrosion occurs when two<br />
dissimilar metals are in electrical contact<br />
<strong>and</strong> connected by an electrolyte. An<br />
electrolyte conducts electricity <strong>and</strong> can<br />
be water solutions containing salts or<br />
acids - <strong>and</strong> need not be concentrated <strong>for</strong><br />
the effect to take place.<br />
The effects of galvanic corrosion begin to<br />
play an important part when an aluminium<br />
<strong>rainwater</strong> outlet is used in conjunction<br />
with metallic membranes, such as lead or<br />
copper.<br />
The Electromotive Series provides an<br />
insight to the corrosion effects between<br />
dissimilar materials.
The Electromotive Series<br />
The susceptibility of different metals to<br />
corrosion whilst in contact with each<br />
other depends upon the difference<br />
between the contact potentials. The<br />
greater the potential difference, the<br />
greater the tendency <strong>for</strong> corrosion. The<br />
metal with the higher negative potential<br />
<strong>for</strong>ms the anode <strong>and</strong> is corroded<br />
preferentially.<br />
Some examples from the Electromotive<br />
Series are shown opposite <strong>for</strong> illustration.<br />
Material Selection Tips<br />
■ For applications when dissimilar<br />
materials are in contact with each<br />
other wherever possible, select<br />
materials to be as close as possible<br />
to each other in the Electromotive<br />
Series. For example, if a roof is<br />
copper clad, select a gun-metal outlet<br />
as gun-metal is around 88% copper,<br />
this closely matches the cladding<br />
material.<br />
■ Where dissimilar metals cannot be<br />
readily avoided, care must be taken<br />
to electrically insulate the adjacent<br />
materials. For example where lead is<br />
dressed into an aluminium alloy<br />
outlet, carefully paint the aluminium<br />
body <strong>and</strong> clamp components with<br />
good quality bitumen paint or use an<br />
insulating gasket material such as<br />
neoprene sponge. Ideally, a gun-metal<br />
outlet should be used in conjunction<br />
with lead clad <strong>roofs</strong>.<br />

Appendix 2 Typical Roof Construction Detail<br />
Warm Roof<br />
A warm roof is where the main mass of<br />
the roof structure lies below the main<br />
thermal insulation. The waterproof<br />
membrane is positioned above the<br />
insulation.
Inverted Roof<br />
An inverted roof is a <strong>for</strong>m of warm roof<br />
where the main mass of the roof structure<br />
lies below the main thermal insulation,<br />
however, the waterproof membrane lies<br />
beneath the thermal insulation.<br />
Un-insulated Roof<br />
A roof without thermal insulation. This<br />
type of construction is only permitted in<br />
non-habitable buildings, e.g. garages.<br />
Cold Roof<br />
A cold roof is where the main mass of the<br />
structure lies above the thermal<br />
insulation.<br />

frame or deck support. The waterproof<br />
membrane must be fully dressed into the<br />
outlet body <strong>and</strong> securely clamped under<br />
the membrane clamp.<br />
Practical Design/Installation Tips<br />
✓ Do not design <strong>for</strong> the maximum outlet<br />
hydraulic capacity, allow a 10% factor<br />
of safety margin <strong>for</strong> intense storms<br />
<strong>and</strong> leaf/debris blockage.<br />
✓ Always allow <strong>for</strong> a back-up outlet,<br />
even though only one outlet may be<br />
required.<br />
✓ Rainwater <strong>outlets</strong> should be inspected<br />
<strong>and</strong> cleaned at least every 6 months<br />
to ensure reliable <strong>and</strong> continuous<br />
operation.<br />
Threaded Outlets<br />
For all ACO <strong>Fulbora</strong> threaded <strong>outlets</strong> (HP<br />
Vertical Screw <strong>and</strong> Two-Way <strong>outlets</strong>) are<br />
provided with female parallel threads<br />
con<strong>for</strong>ming to BS 21:1985 <strong>for</strong> direct<br />
connection of threaded tube con<strong>for</strong>ming<br />
to BS 1387:1985. This tube is supplied<br />
with a taper male thread con<strong>for</strong>ming to<br />
BS 21:1985, which ensures a <strong>watertight</strong><br />
joint when fully screwed into the unit.<br />
Threaded <strong>outlets</strong> are particularly<br />
recommended where a connection to the<br />
outlet is made within the thickness of the<br />
concrete slab. In these applications, the<br />
threaded connection creates a completely<br />
<strong>watertight</strong> seal.<br />
Where a PVC-u screw thread connector<br />
(STC) is used in conjunction with threaded<br />
<strong>outlets</strong>, the screw thread connector<br />
should be assembled with PTFE tape to<br />
ensure a <strong>watertight</strong> seal.<br />
Balcony Outlets<br />
The <strong>flat</strong> grating is configured with an<br />
array of eccentric grating slots that can<br />
be readily cut on site with a hacksaw to<br />
accommodate a downpipe.<br />
Mk 3 Raising Rings<br />
Where applicable, raising rings <strong>for</strong> the Mk<br />
3 range of <strong>rainwater</strong> <strong>outlets</strong> are simply<br />
assembled to the clamp ring by the same<br />
twist action that fixes the dome grate to<br />
the clamp. No fixings or loose<br />
components are required.<br />
For increased height requirements, Mk 3<br />
raising rings can be cascaded together.<br />
The dome grating attaches to the raising<br />
ring by the same action.<br />
Mk 3 raising rings cannot cannot be cut to suit a<br />
specific height requirement. Raising rings<br />
from the Mk3 <strong>and</strong> HP range of products<br />
are not not interchangeable.<br />
HP Circular Raising Rings<br />
HP raising rings can be used <strong>for</strong> domed<br />
grating <strong>outlets</strong> <strong>and</strong> terrace gratings only.<br />
HP raising rings cannot cannot be used with <strong>flat</strong><br />
gratings.<br />
HP raising rings are secured with<br />
stainless steel fixings that are supplied<br />
with each raising ring product.<br />
Where required, the HP raising rings may<br />
be easily cut on site to a specific height<br />
using a hacksaw (<strong>for</strong> example, when using<br />
a terrace grate in conjunction with paving<br />
slabs).<br />

Balcony/Gully Outlet Raising<br />
Rings<br />
Raising rings <strong>for</strong> balcony <strong>outlets</strong> <strong>and</strong> gully<br />
<strong>outlets</strong> are available <strong>and</strong> per<strong>for</strong>m a similar<br />
function as the HP Circular raising rings<br />
as previously described. Separate<br />
stainless steel fixings are supplied with<br />
each unit.<br />
Deck Supports<br />
ACO deck supports are recommended <strong>for</strong><br />
metal decked roof construction <strong>and</strong> are<br />
suitable <strong>for</strong> installation on all types of<br />
metal decked <strong>roofs</strong>. Deck supports have<br />
pre-drilled holes <strong>for</strong> ease of fixing.<br />

Refurbishment Outlet<br />
Refurbishment <strong>outlets</strong> are designed to<br />
conveniently fit within the existing<br />
<strong>rainwater</strong> outlet of the roof that is being<br />
refurbished, which means there is no<br />
need to remove the existing <strong>rainwater</strong><br />
outlet.<br />
Refurbishment <strong>outlets</strong> incorporate a high<br />
per<strong>for</strong>mance domed grating <strong>and</strong><br />
optimised tail pipe to maximise flow<br />
through the unit. The labyrinth finned seal<br />
ensures a <strong>watertight</strong> connection to the<br />
existing pipework. Two sealable access<br />
points within the body enable PU foam to<br />
be injected to fill the void between the old<br />
<strong>and</strong> new outlet.<br />
Step 1<br />
Strip back all roof coverings to the deck<br />
level. Clean out old outlet with wire brush<br />
<strong>and</strong> flush with clean water.<br />
Step 2<br />
Form timber frame around old outlet <strong>and</strong><br />
lay insulation board/vapour barrier<br />
(35 mm minimum).<br />
Step 3<br />
Check clearance <strong>and</strong> trim tail pipe to<br />
length with hacksaw if necessary.<br />
Step 4<br />
Push on flexible labyrinth seal.<br />
Step 5<br />
Flush with clean water to lubricate <strong>and</strong><br />
insert tail pipe into existing pipework.<br />
Seat flange on timber frame.<br />
Step 6<br />
Screw flange to timber frame.<br />
Step 7<br />
Inject PU foam through one port <strong>for</strong> 5<br />
seconds. Remove any surplus.<br />
Step 8<br />
Blank off ports with captive screws.<br />
Complete installation <strong>and</strong><br />
weatherproofing.
