To prevent conditioned air from migrating into the attic space and hot attic air from migrating into the house, Global Dwelling installed this insulated pull-down stair cover. Fabricated with foil-faced rigid foam board with an air sealing gasket fixed along the base to prevent leakage, the cover allows stairs to neatly fold up into the insulated cavity.
This is a new construction project that we recently did. The walls were 2x6" and in order to install cellulose we had to install netting over the studs and stapled it every 1/2" to support the pressure of the installed cellulose. Once its in the wall its very stable and a good air sealer.
