Reliable Spray Foam

INSULATION

From homes to workshops and remote cabins across Alaska, we’ve got you (and your walls) covered.

SPRAY FOAM INSULATION IS The BEST FOR ALASKA’s BUILDINGS

Chinook Foam & Coating specializes in remote Alaskan projects. No location is too far.

HEALTHIER HOMES

Spray foam creates an airtight barrier, sealing your home from air and moisture leakage to improve indoor air quality. It helps protect your family’s health by preventing mold growth, allergens, and airborne pollutants.

ENERGY EFFICIENT

Up to 40% of your home’s energy loss is due to air leakage through holes, cracks, and unsealed gaps — leading to higher heating costs, especially in Alaska’s harsh winters. Spray foam eliminates these weak points, providing superior insulation that ensures consistent indoor temperatures and lower energy bills.

LONG LASTING

Unlike fiberglass or cellulose insulation, spray foam won’t sag, settle, or deteriorate over time. It maintains its structure and effectiveness for decades, making it a one-time investment in energy efficiency.

Live in a More Energy Efficient, Comfortable, and Healthier Building

Spray foam is not only ideal for new residential, commercial, and industrial construction but is equally suited for renovations, remote cabins, metal buildings, and machine sheds.

Protective Coatings & Weatherproofing

Chinook Foam & Insulation also applies damp exterior proofing to concrete foundations, basements, and roof coating systems.

The Science behind savings

What is Insulation R-value?

R-value measures how well insulation resists heat flow. The higher the R-value, the better the insulation.

Equation for R-value showing R = ΔT / φq, with explanations. R is the R-value, ΔT is the temperature difference between surfaces, φq is the heat flux through the barrier.

DECREASED WALL DEPTH

Spray foam provides higher R-values in less space. Traditional insulation requires thicker walls (2x6 framing) to achieve high R-values, while spray foam allows for 2x4 framing without sacrificing insulation performance, reducing construction costs and maximizing interior living space.

REDUCED THERMAL LOAD = Lower Energy Costs

Because spray foam creates a seamless air barrier, it reduces thermal load — meaning your heating and cooling systems don’t have to work as hard. This leads to smaller HVAC system requirements and lower energy expenses year after year.

Spray Foam Insulation FAQ

  • The cost of spray foam insulation depends on the size of your project, location, and the type of spray foam used. We provide custom estimates—contact us for a quote.

  • Yes! Once cured, spray foam is non-toxic and does not emit harmful fumes. It improves indoor air quality by reducing moisture and airborne contaminants.

  • Absolutely. Spray foam insulation is ideal for Alaskan climates, as it prevents heat loss and helps buildings maintain stable indoor temperatures even in subzero conditions.

  • Yes! We specialize in insulation for remote cabins, lodges, and buildings in the Alaskan bush. No project is too far—we’ll travel wherever needed.

  • Spray foam insulation is designed to last the lifetime of the building without sagging, settling, or deteriorating.
