990 systems do not rely on the silicone face for their rating; the foam is impregnated with fire retardant material, meaning the rating is not compromised due to vandalism or damage to the silicone face
Fire foam seals are water tight and also have sound attenuation qualities
This system is coated on both sides so either face can be exposed
Seal material is UV stable, and resistant to solvents
Capable of handling vertical and horizontal joint movement
Open cell foam is constantly self-expanding, allowing system to maintain a watertight seal while undergoing rapid joint movement
990 foam seals come pre-compressed for installation ease
