Specifically designed to work with existing fire resistant doors, Halspan’s acoustic seals offer protection against both noise and cold smoke, but not fire.
The seal’s semi-rigid base and three flexible blades act like triple glazing to give maximum acoustic performance tested in accordance with recognised international standards. Ultra soft and smooth, the blades also help to minimise opening and closing forces.
Halspan’s acoustic seals come in two varieties. They can either be:
•fitted into a 3mm wide saw cut, or
•retro-fitted using a strong, high tack double sided self-adhesive strip.
