FAQ
SPRAYMAN Spray Foam conforms tightly to surfaces, creating an airtight seal that significantly improves thermal and sound insulation compared to traditional materials.
Unlike many cheaper spray foams, SPRAYMAN is Class A Fire Rated under ASTM E84. It offers user-friendly, precision application, ideal for both DIY and professional use.
Class A is the top class for interior wall and ceiling finishes under ASTM E84: Flame Spread Index 0 to 25, with a Smoke-Developed Index of 450 or less. Class B is 26 to 75 and Class C is 76 to 200. It measures how flame spreads across a surface, not how long an assembly holds back a fire.
It shows how fast flame spreads across the material under ASTM E84, and Class A is the top class. It is not a measure of how long the material holds back a fire.
Class A rated insulation foam covers large areas and carries an ASTM E84 classification. Fire block foam seals gaps around critical areas like electrical boxes but is not intended for broad insulation.
Many inexpensive fillers, used mainly for gap or crack filling, lack genuine insulation properties and fire ratings. SPRAYMAN Spray Foam is an insulation product and Class A Fire Rated under ASTM E84.
Old insulation may require removal during renovations or if poorly installed. Removal is done mechanically by cutting away the foam.
For roughly 1,000 sq ft at 1-inch thickness, you’ll need about 50 cans. Use the SPRAYMAN spray foam calculator for precise estimates.
It’s best to vacate during application due to fumes. Return after 12 hours once the foam has ventilated and cured.
Follow guidelines: prepare surfaces, apply at recommended temperatures, use multiple layers, and perform regular inspections.
No insulation is fully waterproof, but SPRAYMAN’s closed-cell spray foam is one of the most water-resistant. Suitable for exteriors but avoid prolonged water exposure.
