The role of glass fiber: enhance rigidity and heat resistance:
GRECHO Fiberglass coated mats serve a variety of purposes and help increase the fire resistance of drywall. First, it increases the rigidity and strength of the board, making it less likely to deform or collapse when exposed to high temperatures. Fiberglass reinforcement distributes stress more evenly throughout the panel, preventing it from buckling or breaking during fire conditions. As a result, drywall with fiberglass-coated mats maintains structural integrity longer, giving occupants more time to safely evacuate a burning building.

Second, GRECHO coated fiberglass facer significantly increase the heat resistance of drywall. During a fire, the fiberglass mat acts as a barrier, slowing the transfer of heat through the panels. Delayed heat penetration limits the spread of fire, giving occupants and first responders the time necessary to contain the fire or evacuate the affected area.
A third advantage of GRECHO fiberglass coated matting is its ability to reduce smoke production during a fire. The fiberglass layer absorbs and immobilizes volatile organic compounds (VOCs) present in flammable materials within the drywall. This absorptive property suppresses the release of volatile organic compounds and subsequent smoke, which can impede visibility and cause breathing difficulties.
