Insulation Services - Attic Hatch Opening Air Sealed
One last important feature is the attic hatch. This is the largest barrier between your conditioned space and the attic. In order to air seal this space, we caulked the framing joints, installed weather stripping around the hatch cover, but we also insulated the hatch with 4" of polysio foam board (that's the silver, cardboard looking stuff you see in this picture).
