VEXTRA® (GLV-TP) Cloth

VEXTRA® (GLV) is a heavy duty, heavy weight, fiberglass fabric coated with vermiculite. These products have been tested and FM approved as a welding curtain. The vermiculite coating acts as an armor—it is inorganic, chemically inert, noncombustible, odorless and provides 50% more protection from direct flame than standard fiberglass. With VEXTRA (GLV) heat travels across the fabric and not through it. AMI’s VEXTRA product is rated at 1000°F and remains stable to 1500°F.

VEXTRA® Textiles are 100% fiberglass coated with a golden vermiculite solution made of plate-like mineral crystals. This non-combustible coating acts like armor when heat strikes the fabric, causing the heat to travel across the fabric rather than through it, shielding the fiberglass from the heat source.
