As the name suggests, Halspan’s threshold seals seal the gap between the bottom of the door and the threshold, providing acoustic, fire and smoke, draught and light nuisance protection, as well as a barrier to dirt and insects.
Fully mortised into the bottom of the door, the seal is lowered and self-levelled to the floor when the door is closed. On opening the door, the seal lifts clear of the floor and retreats into its housing.
The threshold seal is available in a range of different widths, offering either 30 or 60 minutes fire resistance. In true Halspan fashion, it has been fully tested and certified.
