Insulate Indoor Attic Access

To insulate an attic hatch you need weather stripping rigid foam board and fiberglass batt insulation.

Insulate indoor attic access.

Most insulation i find in the attic of homes is air permeable air can travel through it. First install foam weather stripping on the inside of the trim or directly onto the hatch. Cut out two pieces of rigid foam board that are 1 4 inch smaller than the hatch so homeowners can slide the attic access panel open easily. Because the simplest and cheapest way to insulate an attic is to add material to the floor.

The access door is in our closet which is fine except the fact that the crawl space has very little insulation and neither does the door. More insulation 6 inches or 8 inches isn t uncommon. Then add insulation batting to form a pillow and wrap it up like a birthday present as shown. Plan to pull up the flooring and layer new insulation on top of the old.

This means while your insulation in the attic may slow the flow of heat via radiation it will not stop air flow from the living space which carries heat via convection if there is a path for air to travel. But if the floor is covered in plywood you can t stuff enough insulation beneath it to do the job sufficiently not even in warm climates. Staple long pieces of duct tape sticky side up onto the attic scuttle door. For air to move there must a path hole in the ceiling crack in the drywall poorly sealed attic scuttle etc and a difference in pressure.

Here s one good method. That means that you should glue at least 4 inches of foil faced polyisocyanurate r 26 to the box. The rule here is simple. Add insulation to the exterior of the plywood box.
