Look at the whole opening.
A hatch can be under-insulated, poorly fitted or missing a continuous seal at its perimeter. We review the lid, frame and access arrangement to identify practical improvements.
Insulation and weatherstripping.
Suitable insulation at the hatch and weatherstripping at the contact surface can be included in the scope. The details should allow the hatch to close properly and remain usable.
Keep insulation where it belongs.
The access area may need suitable containment to keep loose-fill insulation from falling into the living space when the hatch is opened. The solution depends on the opening and the amount of insulation planned.
Connect the details. Insulation, ceiling air sealing, attic ventilation and household exhaust are considered together when planning the scope.
