How HD Spray Foam Insulation Is Installed

Achieving the best energy efficiency in a home or building requires proper insulation. While fiberglass is typically used, HD Spray Foam can do a better job of sealing the tiny cracks and gaps that let heat in during the summer and out during the winter. It’s also more durable and can stand up to high winds better than fiberglass.

However, there are some downsides to using spray foam insulation. For one, it emits a lot of volatile organic compounds during the spraying process and as it cures, which can make it unpleasant to be in a room that is being sprayed. Additionally, it can be dangerous to handle without proper training, which is why professional installers are recommended.

Spray Foam Insulation for Attics and Roofs

The installation of spray foam insulation starts with prepping the area, which usually includes cleaning and covering it in plastic sheeting to protect surrounding areas from the chemicals. Then, the installer drills two holes through each stud cavity in a wall or roof in order to spray the foam in. The foam is sprayed in layers, and each layer expands as it dries to fill the space and create an effective air and vapor barrier.

The foam contains little pockets that create barriers that help it resist the flow of heat and vapor, which cuts down on a home’s utility costs. However, it’s important to note that the second law of thermodynamics states that heat flows from warm places to cold ones. Spray foam insulation can effectively stop this movement, but it isn’t always a good idea to install it in a humid or damp area.
