Insulation – Spray Foam

Spray Foam InsulationSpray Foam insulation is one of the best ways to insulate your home because it air seals and insulates at the same time. This is a key component in making your home more energy efficient and to help lower your utility bills and increase the comfort of your home. We use two different types of spray foam: open cell or low density foam, and closed cell or high density foam. Closed cell spray foam has a higher R-value per inch when compared to open cell spray foam; however it is also more costly. Remember, the higher the R-value, the better the insulation.

We find the best areas for spray foam are on the rim joist (the area in your basement where the wood frame sits on the masonry foundation), crawl spaces, basement walls, and in the attic. Of course, if you are expanding your home or building new and the exterior walls are exposed, this is a great time to insulate them with spray foam.

We often convert the attic into what is called a “hot roof assembly.” In a “hot roof assembly” we seal off all the venting in the attic and spray foam the slope, or underside of the roof, as well as the gable end walls creating a cocoon like effect. This is typically done when there is an air handler for heating/air conditioning in the attic space. This is beneficial both in the summer and winter. In the summer time, for example, when the attic is 120+ degrees the system is working twice as hard to cool your home because it is in this extremely hot environment. The spray foam insulation will help keep the temperature of the attic much cooler and similar to the main living area. We are turning your attic into a conditioned space and expanding the thermal envelop. You can think of it like a cathedral ceiling. In this scenario, it is perfectly safe to seal up the attic as it no longer needs to breathe. The spray foam also air seals the attic which is great for keeping the heat in your home during the winter.
