G & M Insulation provide quieter, more energy efficient insulation with brands such as INSULSTAR and SEALITE for your home or business. We are a locally-owned spray foam insulation contractor based in Kingsport, TN.


InsulStar® is the most energy-efficient, environmentally friendly, closed-cell spray-in-place polyurethane insulation system available. It is formulated from renewable agricultural resources and is odorless and completely non-toxic after installation. It stops air flow into and out of your home, reduces noise, and blocks dust, pollen and other airborne pollutants for a more comfortable environment.

InsulStar® is a two-part liquid that is sprayed in place by specially trained G & M Insulation contractors. This liquid quickly expands, filling all gaps and voids, conforming to any shape space and cures to form a fully adhered, solid, monolithic insulation envelope. InsulStar's high R-value allows designers to reduce the depth of exterior walls and still obtain high energy efficiency

By designing and building a highly energy-efficient home, the reduction in energy demands for heating and cooling will lower demand on utility companies for the life of house. With InsulStar® you can insulate directly to the roof deck, bringing all of the space under the roof into use. By putting HVAC ductwork in conditioned space, energy waste from leakage is eliminated.

Insulstar Environmentally Friendly Foam Insulation

InsulStar is formulated with renewable agricultural resources and uses a state-of-the-art, environmentally friendly blowing agent with zero Ozone Depletion Potential.

InsulStar high-performance insulation is a nominal 2.0lb/cu. ft. density, closed-cell spray foam (SPF) that can be sprayed in place that adheres to oddly shaped surfaces. InsulStar's R-value is above R 6.4 per inch, compared to fiberglass bat at R 3.5. InsulStar will stop air infiltration and eliminate convective looping which saves you, the building owner, a tremendous amount of energy (i.e., MONEY).

InsulStar is formulated with renewable agricultural resources and uses a state-of-the-art, environmentally friendly blowing agent with zero Ozone Depletion Potential. It's because of products like InsulStar that our company was awarded the international 2004 Stratospheric Ozone Protection Award from the EPA for our commitment to developing environmentally friendly SPF insulation systems.

Once applied, InsulStar expands to fill all gaps and cavities to form a barrier that blocks air infiltration, noise pollution, dust, and pollen from entering your building. The low moisture vapor permeance eliminates the need for any additional vapor barriers in most applications which saves you money. Plus, this low permeance works to control moisture vapor movement so there's not accumulation of mold-supporting moisture in your building's walls. InsulStar is blended with an anti-microbial to inhibit mold, mildew, and bacterial growth as well, maximizing comfort and health to all of your building's occupants.

InsulStar also adds structural rigidity to your building's walls. In fact, in a test conducted by the National Association of Home Builders Research Center, a 2x4 wall sprayed with polyurethane foam insulation like InsulStar had two times the racking strength of a wall filled with fiberglass batt insulation. InsulStar sprayed inside on a plywood roof deck increases the wind uplift resistance by over two and a half times that of standard nailing strength.

Sealite™ SPF insulation technology seals your home against air infiltration and the pollutants, pollen, and dust that could otherwise come inside through fiber-based insulations. Sealite™ even provides an invisible buffer from unwanted noise pollution, adding further to the comfort and enjoyment of your home.

How Does Sealite™ Spray-in-Place Insulation Work?

Sealite™ is a two-part liquid that is sprayed in place by specially trained and experienced G & M Insulation contractors. Our liquid mixture expands quickly to fill all gaps and voids in your home’s exterior walls. It cures to form a fully adhered, solid, monolithic cellular insulation envelope.

Where Can Sealite™ Be Used?

Sealite™ can conform to any shaped space, so your architect and builder can use it on every exterior surface of your home between conditioned and unconditioned spaces. By using Sealite™ spray-in-place foam insulation, your home will be protected inside an environmental envelope that maximizes your home’s energy performance and reduces external air infiltration. Plus, Sealite™ SPF will not shrink, sag, or settle, increasing your home’s structural integrity.
