Frequently Asked Questions about Foam Board Insulation

How do foam board insulation work?

Foam board insulation works by providing a barrier between the inside and outside temperatures of a structure. The foam material contains millions of tiny air pockets that slow down the rate at which heat can transfer through them. This means that in the winter, the warmth from your heating system stays inside the house, and the cold air stays outside. In the summer, the process is reversed, keeping your air conditioned air inside and the heat out.

What's the best way to install foam board insulation?

The best way to install foam board insulation depends on where you’re installing it. For example, foam board installed in a basement or exterior wall might require different installation methods than foam board installed in an attic. However, the general steps typically involve: measuring and cutting the foam board to fit the space, attaching it directly to the framework of the area being insulated, and then sealing any seams with a foam sealant or tape. Always remember to check local building codes or consult with a professional before beginning this kind of project.

Can foam board insulation be painted or covered?

Yes, foam board insulation can be painted or covered. However, if you're intending to paint the foam board insulation, make sure to use a paint that's suitable for foam as some types of paint can damage the insulation.
