How do I determine the R-value I need for my project?

The R-value of foam board insulation refers to its resistance to heat flow. Consult local building codes and consider your climate to determine the required R-value for your project. Higher R-values provide better insulation.

What kind of adhesive do I need to attach foam board insulation to my walls?

Most foam board insulation is designed to be attached to a construction adhesive and is available in tubes or cartridges. Ensure the adhesive is specifically designed for foam insulation and the surface to which it is attached.
