E84 Class 1(A)

E84 Class 1(A) low pressure spray polyurethane foam is a two-component system designed to fill and insulate large voids and surfaces. Handi-Foam E84's excellent adhesion properties create a continuous air barrier. This quality completes the building envelope, resulting in improved indoor air quality and lower heating and cooling costs. Handi-Foam E84 is a Class 1(A) fire rated foam that meets various building code requirements for insulation.

Properly applied Handi-Foam E84 reduces energy consumption, leading many homes or buildings to be certified in their respective energy designation. Handi-Foam E84 is also UL GREENGUARD™ Gold Certified.

Handi-Foam E84 is available in a variety of disposable and refillable sizes and is dispensed using the patented Handi-Gun® Dispensing Unit.
