ThermoSeal spray foam gives builders a competitive edge: higher HERS scores, faster enclosures, no ignition barrier headaches, and a lifetime warranty you can hand to every buyer. From residential new construction to large-scale commercial builds, ThermoSeal performs.
Spray foam isn't just better insulation; it makes the whole build perform better from framing through buyer handoff.
Spray foam virtually eliminates air infiltration, the largest single factor in HERS ratings. ThermoSeal-insulated homes routinely achieve ENERGY STAR certification and sell at a premium.
ThermoSeal closed cell foam reaches full density in seconds. One pass achieves code-minimum R-values without multiple layers of batts, vapor barrier, and separate air barrier systems.
ThermoSeal HFO is approved for unvented attic and crawl space use without an ignition barrier per ICC-ES AC377 Appendix X. Fewer materials, faster inspection, cleaner detail.
ThermoSeal closed cell foam bonds to framing and adds racking strength to wall assemblies: compressive strength up to 29.5 PSI, tensile up to 56.8 PSI. Less reliance on sheathing in some assemblies.
ThermoSeal's lifetime warranty transfers to new owners, a powerful selling point that distinguishes your homes from builders still using fiberglass batts. Offer it as a marketing feature.
ThermoSeal HFO reaches 0.86 perms at just 1.37", meeting Class II vapor retarder requirements in most climate zones. Eliminates the need for a separate poly vapor barrier in wall assemblies.
ThermoSeal products are engineered for every build type, from single-family homes to large commercial wall assemblies.
Achieve tighter envelopes from day one. ThermoSeal spray foam eliminates the need for separate air barriers, vapor barriers, and ignition barriers in attic assemblies, simplifying your build sequence and reducing subcontractor coordination.
Spray foam's ability to conform to irregular cavities and reach difficult-to-access areas makes it ideal for retrofit applications where batts simply can't provide a reliable air seal.
ThermoSeal 5G is built for the demands of commercial construction: NFPA 285 compliant for Type I–IV buildings of any height, with the structural performance commercial projects require.
ThermoSeal HFO is rated for 286 mph wind uplift (UL 1897), ideal for hurricane zones, coastal builds, and IBHS Fortified Home certifications.
Four products cover every project requirement. Key distinction: only ThermoSeal 5G has NFPA 285 for commercial exterior walls.
Water blown, 100x expansion, NRC 0.75 sound dampening, STC 39. Air impermeable per IRC/IBC/IECC. Ideal for interior applications where sound control and air sealing are primary goals.
Enhanced density open cell, 75x expansion, NRC 0.65. Superior dimensional stability vs. 500. Preferred for applications requiring higher density and improved structural performance from an open cell product.
HFO blown (Forane 1233zd), vapor barrier at 2", 286 mph wind uplift, no ignition barrier in attics. Does NOT have NFPA 285; do not specify for commercial exterior wall assemblies requiring NFPA 285.
Commercial and industrial grade. Only ThermoSeal product with NFPA 285 compliance for exterior wall assemblies. Higher tensile strength (56.8 PSI) vs. HFO. Required for Type I–IV commercial buildings.
