Approved Document ‘M’ requires that the force to operate a door leaf should not exceed 20N on accessible routes. It is likely that this performance requirement might not be achievable for some locations where closer forces and the influence of seals used for smoke sealing or acoustic performance requirements will add to operating forces.
We provide an extensive range of threshold drop seals that may be used for smoke sealing purposes (where the under door gap
exceeds 3mm) or for sound attenuating, light tight or other performance requirements. All our threshold drop seals incorporate Pemko’s patented low friction ‘Feather Touch’ technology resulting in minimal operating forces.
Optimum performance is achieved when the seal is adjusted to grip a 50-70 gsm piece of paper that can be withdrawn without tearing.
Unless otherwise specified, the seal element consists of a closed cell sponge neoprene insert to Pemko’s patented ‘tri-fin’ design. The seal maintains pliability down to -70°F. The sealing element benefits from good ‘memory’ and durability characteristics. Other seal element options are available where specified.
