An R-38 of blown-in cellulose insulation has been installed in the attic.

Cellulose insulation is installed at an R-38. This insulation is made of 85% recycled materials and is fire retardant because it has been manufactured with borate.
After Foam Board Dam in Attic Access P 2
A foam board dam is installed around the attic access to provide a clean finish and ensure that no insulation falls into the access.
