Attic & Roof Insulation

Cathedral ceiling insulation that works in tight rafter bays without trapping moisture

Vaulted ceilings have little room for insulation and ventilation. Dense-pack, rigid foam and spray foam options make the most of the space.

Cathedral Ceiling Insulation

A cathedral ceiling has the roof and the ceiling in the same plane, so the rafter depth limits how much insulation fits. If a vented bay is stuffed full, moisture and mold can follow, and if it is under-insulated, the room is hot in summer and cold in winter.

We insulate cathedral and vaulted ceilings across Nashville and Middle Tennessee. We choose between dense-pack, closed-cell foam and rigid foam based on how the roof is built, whether it is vented and what is above and below.

FAQ

Common questions about cathedral ceiling insulation

Can you insulate a finished vaulted ceiling?

Often through access from the attic edges or by opening small sections. We explain the options after an inspection.

Should a cathedral ceiling be vented?

It depends on how the roof was built. We check before choosing the method.

Why is my vaulted room so uncomfortable?

Thin insulation and leaks at the top plate and ridge are usual causes.
