Spray Foam Insulation

Spray Foam Insulation Installers in Murfreesboro, TN

Spray foam insulation is a dual-acting product that insulates and seals air leaks with one product. Spray foam insulation differs from fiberglass and cellulose insulation by adding R-value and sealing air leaks in one step. As it is applied, spray foam insulation expands to completely fill the cavity and prevent air leakage.

While air sealing can be added to a fiberglass or cellulose insulation project, spray foam insulation accomplishes both in one pass to help save energy and money. Spray foam insulation can be used in nearly any insulation project.

Open Cell Spray Foam

Open cell spray foam and closed cell spray foam both insulate and air seal in one. Open cell spray foam has a lower R-value per inch than closed cell spray foam. Open cell spray is defined as such because when applied, the cells (bubbles) in the foam open. Open cell spray foam is better suited for some applications than closed cell spray foam.

Open cell spray foam insulation is vapor permeable, can accommodate seasonal movement and is not a food source for mold. B&M Insulation applies ENERTITE® open cell spray foam from BASF.

Closed Cell Spray Foam

As with open cell spray foam insulation, closed cell spray foam provides both insulation and air sealing. In contrast with open cell spray foam, closed cell spray foam is solid – the cells of the bubbles remain closed. This results in a more rigid product than open cell and contributes to its higher R-value per inch. The rigidity of closed cell spray foam also makes it a top candidate for structural reinforcement helping to strengthen buildings during storms or high winds.

Like open cell spray foam insulation, closed cell spray foam is vapor permeable, is able to accommodate seasonal shifting and is not a food source for mold. With its ability to deflect water and provide a vapor barrier, closed cell spray foam works for both interior and exterior applications and is mostly used for metal siding applications or areas that sweat more. B&M Insulation applies SPRAYTITE® closed cell spray foam from BASF.
