Caice/Flameshield Fire Rated Attenuators
Fire Rating
The risk of fire in any type of building is an ever present concern
and so all measures must be taken at the design stages to
ensure the risks are minimised.
Where a fire strategy is to be adopted, it is usual for certain parts
of the ventilation ductwork to be fire rated, in order to offer the
necessary protective measures for the finished development.
For each individual development, the degree of fire rating
required will depend on a number of variables. The employment
of a specialist sub-contractor to advise on the required fire rating
treatment is therefore essential to ensure that that all relevant
current standards and legislation are complied with.
Fire Rated Attenuators
Attenuators form part of the ventilation systems and must
therefore meet the fire rating requirements for the ductwork in
which they are installed.
There are various specialist fire rating sub-contractors all
offering different systems, however one such company is
Flameshield Ltd.
Flameshield
As one of the UK’s leading providers of fire-rated ductwork,
Flameshield offer the UK’s first non-coated fire-rated ductwork
system that receives LPCB certification.
Made from galvanised sheet steel, the system withstands fire
tests to BS476 Part 24 and BS5588 Part 9, without the need for
additional spray to be applied to the external surface.
Caice / Flameshield Alliance
Caice have worked closely with Flameshield, and are now able
to offer a full range of rectangular galvanised steel fire rated
attenuators. This key strategic alliance offers a number of
benefits to our clients:
1. Attenuators manufactured by Caice are fully approved
and certified for use with the Flameshield range of fire
rated ductwork, removing any doubts over compatibililty
issues.
2. Both Caice and Flameshield use the same manufacturing
technique, where integral flanges are formed from the
parent material of the duct casing. This provides integral
strength and reduced air leakage when compared to
conventional flanging systems such as Doby or MEZ.
3. Caice attenuators and Flameshield duct sections are
visually similar, so there is no mismatch when aesthetics
are a consideration.
4. No spray means no application or curing time, and no
risk of damaging expensive coatings once the product is
on site. Attenuators and ductwork can be produced with
the quickest possible turnaround times at competitive
prices.
