1 Scope
This British Standard specifies requirements for draughtstrip products to fit the
common types of installed doors and windows in housing that were not originally designed
to incorporate draughtstripping, and applies to hinged doors in wood, sliding windows
in wood, hinged windows in wood and steel and domestic loft hatches.
NOTE Unless specifically designed as such, draughtstrips conforming to this standard should not be fitted as smoke control seals without the approval of the fire authority, nor should they be fitted to doors with intumescent seals without the prior approval of the manufacturer of the door or consultation with the fire authority.
Gap filling and in-situ gaskets, applied like sealants, are not dynamic products and
are excluded from this standard. Letter box seals are excluded from this standard
because they do not generally function in the manner of a draughtstrip. Draughtstrip
materials specifically designed for use on the bottom of doors are also excluded from
this standard.
