Hatches, Pull-down Stairs, and Attic Doors
Hatches and pulldown stairs must also be air sealed.
Hatches should be weatherstripped with Q-lon or door kit weatherstripping and caulked around the trim.
Pull-down stairs should be treated with a pull-down stair cover (ThermaDome) or attic tent (tent to be used only if the stair cover will not fit, possibly due to framing or proximity to low rafters.) Make sure to install carpentry if needed to allow the Tdome to sit flush and tight to the opening and seal all gaps and cracks with caulk or foam.
Attic doors should be weatherstripped with a door kit and a door sweep should be installed.
