Spray Foam Insulation

Spray foam insulation is an extremely energy efficient insulation

product that can reduce heating and cooling bills by 40% or more.

IMG_1795Spray foam insulation is a two-in-one product, insulating and air sealing in one step.


Spray foam insulation expands when applied and completely fills a cavity to prevent air leakage and keep energy bills low. This two-in-one aspect makes it a superior product compared to fiberglass or cellulose insulation. Spray foam insulation can also increase the strength of your home, helping to increase stability during high winds and severe storms.


Open Cell Spray Foam

Open cell spray foam insulation works as an insulator and air barrier. The typical R value of open cell spray foam is 3.7 per inch. Other features of open cell spray foam insulation are vapor permeability, ability to accommodate seasonal movement, not a food source for mold, and sound dampening.


Closed Cell Spray Foam

As with open cell spray foam insulation, closed cell spray foam works as an insulator and air barrier. The typical R value of closed cell spray foam is 6.5 – 7.0 per inch.


An exceptional feature of closed cell spray foam is that it is solid. The cells of the foam bubbles remain intact (closed), which makes it rigid. The closed cell composition and increased density contributes to a higher R-value than that of open cell foam, and can also contribute to building stability during storms and high winds.


EcoLogical Insulation installs a variety of brands of spray foam insulation including Icynene, SWD, and Johns Manville.

Bake House Project

Spray foam was installed all of the way to the roof deck. We applied open cell spray foam with DC315 Intumescent paint to achieve a 15 minute thermal barrier since the foam will not be covered with sheetrock. Antique wood was used for the wall covering.
