Requirements for products to fit the common types of installed doors and windows in housing not originally designed to incorporate draughtstripping. Applies to hinged doors in wood, sliding windows in wood, hinged windows in wood and steel and domestic loft hatches.

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.
