PHOS-CHEK® INSUL-8® is a water-enhancing gel specifically designed for municipal, industrial and wildland fire departments for application from ground equipment. Because of its enhanced coverage and unparalleled adherence capability, PHOS-CHEK INSUL-8 offers superior protection for all types of structures. With superior physical and fire protection properties, PHOS-CHEK INSUL-8 can coat most vertical surfaces, including glass, with up to three inches of gel with no slumping. This enables firefighters to easily and quickly protect buildings, tanks and other structures from flame and/or heat impingement, without tying up valuable resources to continuously spray water. PHOS-CHEK INSUL-8 provides an insulating blanket for the protected structures or fuel source to the advancing fire. PHOS-CHEK INSUL-8 also provides protection against water loss due to evaporation, making it more effective than plain water.

PHOS-CHEK INSUL-8 is a liquid concentrate that mixes easily with water by proportioner, eductor, or batch mixer. The mix ratio, or dilution rate, can be varied based on the desired gel thickness and the quality of the water.

PHOS-CHEK INSUL-8 requires significantly less concentrate than other liquid concentrate gels to achieve the same properties, making it far more cost effective. Effective mix ratios are between 0.37% and 3% depending on application and water quality. The product can be expertly mixed and applied using Perimeter Solutions’ PC CODE system

PHOS-CHEK INSUL-8 is fully tested and qualified by the USDA Forest Service. It is safe, non-toxic and environmentally friendly. Cleanup is easy with a garden hose or pressure washer.
