Comfort, installed.
Open cell and closed cell spray foam insulation, built for the pros who install it. Foam is what you spray; comfort is what people buy — ComfortSeal gives you IAPMO-evaluated chemistry, a name homeowners understand, and a limited lifetime warranty on the foam on every certified install.
Homeowners don't buy R-values.
They buy comfort.
We built the brand that sells it — and we're building the network of pros who deliver it. That's where you come in.
Join the Installer Network →Getting your crew spraying ComfortSeal is straightforward — and every certified install is backed for life.
Register in the installer portal and add your crew. Twelve online modules — application techniques, safety, building science and code compliance — with a quiz after each.
Choose ComfortSeal 500 for open cell or ComfortSeal HFO for closed cell, shipped from Mandeville, Louisiana.
Install with full technical support behind you, from rig setup to the final pass.
Hand your customer a limited lifetime warranty on the foam — a closing tool for every proposal.
These are the talking points that sell spray foam to homeowners — and ComfortSeal delivers every one of them.
Spray foam insulates and air seals in one step, so the heating and cooling you pay for stays inside — month after month.
Fewer freezing bedrooms and sweltering bonus rooms. Sealing the envelope evens out temperatures room to room, floor to floor.
ComfortSeal 500's open cell structure absorbs sound: NRC 0.75 and STC 39 (ASTM C423, E413) take the edge off street noise and noise between rooms.
ComfortSeal 500 tests at under 0.002 L/s·m² air leakage (ASTM E283), so less outdoor air — and the dust it carries — drifts in through the walls. A tight house needs planned ventilation, which your installer or HVAC contractor sizes.
ComfortSeal HFO is a Class II vapor retarder at 2 inches (0.45 perms, ASTM E96) — the right call for humid climates, crawl spaces and coastal builds.
Closed cell ComfortSeal HFO cures rigid and is tested to 210 psf wind uplift (UL 1897) — a published figure for high-wind zones.
Tap any part of the house to see which ComfortSeal product belongs there — and what it does for the people inside.
The attic is where homes leak the most air. ComfortSeal 500 expands 100× to fill around framing, wiring, and can lights — and its open cell structure absorbs the sound of rain and traffic.
A deliberately simple lineup: open cell for air sealing and sound control, closed cell for more R-value in the same depth and vapor control. Both IAPMO-evaluated, with full documentation.
The side-by-side your customers should see before they settle for fiberglass or cellulose.

Plain-English answers to the questions homeowners and pros ask most, written from the published IAPMO report tables rather than rules of thumb.
What contractors, builders, and their customers ask most about ComfortSeal products.
ComfortSeal is a spray polyurethane foam insulation brand made by USAFoam, LLC, a manufacturer at 1744 South Lane, Mandeville, Louisiana. It offers two products: ComfortSeal 500, an open-cell foam (IAPMO ER-974), and ComfortSeal HFO, a closed-cell foam (IAPMO ER-975). Both are installed only by ComfortSeal-certified contractors and carry a limited lifetime warranty on the foam.
ComfortSeal is a spray foam insulation brand built for contractors and builders working in residential construction. It's a liquid-applied insulation that expands on contact to fill wall cavities and seal around framing, wiring and penetrations. The lineup is deliberately simple: ComfortSeal 500 (open cell) and ComfortSeal HFO (closed cell).
ComfortSeal 500 is a light density open cell foam (0.5 lb/ft³, water blown) with R-13 in a 2x4 wall (3.5 inches), 100× expansion, and sound dampening of NRC 0.75 and STC 39 — suited to interior walls, attics, and sound control. ComfortSeal HFO is a medium density closed cell foam (2.0 lb/ft³, HFO blown with a GWP of 1) with R-25 in the same 3.5 inches that also acts as a Class II vapor retarder, cures rigid, and is tested to 210 psf wind uplift (UL 1897).
Yes. ComfortSeal provides a limited lifetime warranty on its spray foam, for the life of the home, when it is installed by a certified ComfortSeal contractor. For contractors and builders, it's a closing tool to put on every proposal.
It depends on the house, the climate and what the foam replaces, so be wary of anyone who quotes one number. Spray foam saves because it insulates and air seals in the same step, stopping the leakage that fiberglass and cellulose leave behind. A certified installer can walk you through what to expect for your home.
Register your company in the installer portal, add your crew, and work through twelve online modules covering application techniques, safety, equipment, building science and code compliance. Pass each quiz and the final exam at 80% and the certificate is issued on the spot, valid for two years. Once certified, you join the ComfortSeal installer network with access to technical support and the limited lifetime warranty program. Learn more about training.
Once it has cured, spray foam is a stable, solid insulation. While it is being sprayed it is not: the chemicals are hazardous during application, so occupants stay out while the crew works and until the area has been ventilated and the installer says it is time to return. Certified ComfortSeal installers follow those steps on every job. ComfortSeal HFO's blowing agent has a global warming potential of 1, a small fraction of the older HFC blowing agents it replaces.
