BaySeal® Spray Polyurethane Foam (SPF) Insulation products provide a spectrum of safe, innovative, and cost-effective options for creating a tight, energy-efficient building envelope that’s made to last. Spray Foam Insulation is the only material that creates an air and moisture barrier for precision temperature control and virtually mildew and mold-free performance for the life of your structure. Spray Foam Insulation reduces heating and cooling costs by 40% or more with a tight thermal envelope


Big Cost Savings

A tighter seal means a huge return on investment in lower utility bills – in most cases, Spray Foam Insulation pays for itself in just a few years.

Improved Air Quality

No other insulation material keeps dust, pollution and allergens out as completely as Spray Foam, so you can breathe easier indoors. Keeps out moisture, which prevents mold from forming and taking over your home or office.

Peace and Quiet

Only Spray Foam Insulation creates a barrier that actively reduces outside noise from traffic, construction, weather and more.

Enhanced Comfort

Eliminate hot and cold spots and maintain consistent, comfortable temperature indoors year round with Spray Foam Insulation.
Long-term Performance

Designed to perform for the entire life of the building, Spray Foam Insulation will never sag, gap or settle like traditional insulation, even decades later.

The Tightest Seal Possible

Because it goes on as a liquid, quickly expands, and cures to a solid. Spray Foam is the only way to completely fill cracks and crevices so no air or moisture can pass through. Seals tight to prevent bugs, rodents, and other nasty invaders.

Safety You Can Trust

Spray Foam Insulation products are rigorously tested for safety and contain no CFCs, HCFCs, fibrous materials, formaldehyde or other dangerous chemicals.
