Up to 3x the Racking Strength

ThermoSeal closed cell spray foam doesn't just insulate; it reinforces. With compressive strengths up to 29.5 PSI and tensile strengths up to 56.8 PSI, it adds up to 3x the racking strength to walls and roof assemblies. ThermoSeal HFO is wind uplift rated to 286 mph and approved for fortified roofs.

Cleaner, Healthier Indoor Air

Indoor air quality directly impacts your family's health. ThermoSeal spray foam creates an airtight seal that blocks outdoor allergens, dust, pollen, mold spores, and airborne pollutants from infiltrating your home. Unlike fiberglass, which can trap moisture and promote mold growth, spray foam is an inert material that does not support biological growth.

Frequently Asked Questions

Benefits FAQ

Answers to the most common questions about spray foam insulation benefits.

ThermoSeal spray foam can reduce heating and cooling costs by up to 50%. Air leakage accounts for up to 40% of energy loss in typical buildings. Spray foam eliminates this by creating a continuous airtight seal. Most homeowners see a complete return on investment within approximately 3–5 years through energy savings alone, with savings continuing for the lifetime of the building. Actual savings vary by climate, home size, and existing insulation.
Spray foam outperforms fiberglass in virtually every category. ThermoSeal closed cell provides R-7.3 to R-7.4 per inch versus R-3.1 to R-3.4 for fiberglass. Spray foam creates a complete air seal (fiberglass doesn't), acts as a vapor barrier (fiberglass absorbs water), resists mold, adds structural strength, and lasts a lifetime without sagging or settling. According to U.S. DOE data, "commonly installed" fiberglass batts lose 28% of their labeled R-value due to installation quality.
Yes, particularly open cell spray foam. ThermoSeal 500 achieves a Noise Reduction Coefficient (NRC) of 0.75, meaning it absorbs 75% of sound energy. It also has a Sound Transmission Coefficient (STC) of 39. This virtually eliminates noise from traffic, lawn equipment, construction, and interior room-to-room sound transfer. It's ideal for multi-family housing, home theaters, and studios.
ThermoSeal products are among the most environmentally responsible insulation options. Open cell products are water blown with a GWP of 1, the lowest in the industry. Closed cell products use Forane 1233zd HFO with a GWP of 1, which is 99.9% lower than traditional HFC blowing agents. All products contain zero ozone depleting substances. The energy savings from spray foam also reduce your building's carbon footprint by 40% or more.
ThermoSeal spray foam is inherently resistant to mold and mildew. Unlike fiberglass, which traps moisture and provides a food source for mold, spray foam is an inert material that doesn't support biological growth. Closed cell spray foam also acts as a moisture and vapor barrier, preventing the conditions that cause mold in the first place. This is especially important in basements, crawl spaces, and humid climates.
Yes. Energy-efficient homes consistently command higher resale prices. Spray foam insulation improves your home's energy rating, lowers utility costs for future buyers, and signals a modern, well-maintained property. Combined with ThermoSeal's limited lifetime warranty, which transfers with the property, it's one of the highest-ROI home improvements you can make.
