With the equipment that we have, there is no attic size that we can’t handle. Blown cellulose or blown fiberglass would be the choices, both performing in an effective way. Also, we use either open cell foam or closed cell foam to seal the attic as an option. Vaulted ceilings, walk up attics, or slope ceilings also can benefit by using foam. Regardless of which method you choose, we ensure the R-value you paid for, is the R-value you receive.
