Learn how you can stop energy dollars from escaping through your home's attic hatch.
Air can escape through gaps and cracks in your ceiling, making your heating and cooling systems work harder than they need to. You can reduce that energy loss by insulating and air sealing a leaky attic hatch.
The access hatch is a known problem spot for energy loss. It's best to fix the problem from the indoor side and the attic side for maximum efficiency.
On the attic side, an insulated, removable box made of foam board and batt insulation reduces heat loss while still allowing access. You'll need to measure carefully to ensure a good fit; every attic is different. XPS foam, a bit of construction adhesive and foil tape makes a sturdy box. Next, add a layer of batt insulation to the top of the box. Finally, add weatherstripping to the edge of the box where it will contact the attic frame.
Before placing the box, seal the space between the hatch frame and attic joist with foam or caulk. The finished box is then fitted over the hatch opening on the attic side. It's easily removed and set aside whenever you need to access your attic. Finally, seal the hatch door with adhesive foam weatherstripping.
Insulating and air sealing a leaky attic hatch will help stop drafts, and it will make your home more comfortable and efficient.
