| TASKMASTER
S Series are the first steel doorsets to be awarded a British
Fenestration Rating Council “U value” rating.
The BFRC certificate, which can only be issued
to ISO 9000 registered manufacturers, enables the “U
value” rating of TASKMASTER steel doorsets to be used
by designers when calculating the energy performance of buildings
under the latest edition of Approved Document L2 of the Building
Regulations.
The BFRC certificate certifies that standard Taskmaster doorsets
fitted with sills and thermal seals have a total U value rating
of 3.1 W/m1/K.. This is equivalent to a typical timber doorset
and should enable an averaged window and door U value of 2.2
W/M2 K to be achieved under 'trading off' calculations in
a typical building (this example is detailed in Taskmaster
Technical Data Sheet TD 305).
When 'trading off' is not possible, an alternative
U2 core is available which when incorporated into Taskmaster
S Series doorsets gives a BFRC certified U value rating of
1 .8 W/m2/K.. Doorsets with the U2 core are however more costly
than standard doorsets.
TASKMASTER S Series doorsets also satisfy the Air Leakage
requirements of Part L2, with an air leakage of 1.2 M3 /hour/M2
at 50 Pa pressure (well within the maximum of 10 m3/hour/M2).
