Proper Insulation for Vaulted Ceilings

Often vaulted ceilings are not insulated correctly. For years, fiberglass batt insulation was the only way to insulate vaulted ceilings. Over time, fiberglass batts can slide out of place and compromise your home’s energy efficiency.

When insulating a vaulted ceiling, R-value and moisture management must be addressed. Spray foam insulation can achieve both. Recently our team insulated a custom home with vaulted ceilings. We began by installing two inches of closed cell spray foam. This created a vapor barrier to help prevent condensation from forming on the underside of the roof deck. After installing the closed cell spray foam, nine inches of open cell foam insulation was installed to bring the vaulted ceiling to an R-46.
