A home loses about 25 % of its heat through the top floor ceiling due to the effect of hot air rising. The attic hatch is a very large opening because ceiling which accelerates this impact by allowing that increasing air to escape the home.

For the purpose of this process I am assuming you have an un-insulated plywood attic hatch.

You will need:

2" thick Polystyrene Rigid Insulation
Attic Hatch Weather-stripping
Foam Compatible Glue
Four Hook & Eye Latches or Draw Catches
Straight Edge
Measuring Tape
Insulate the Hatch

Remove your existing attic hatch and determine its size. Cut four pieces of Polystyrene Rigid Insulation about 1/2 inch smaller sized than the dimensions of the hatch. The insulation will both sluggish heat loss and include ballast to the hatch to improve the seal at the weather-stripping. Utilize the foam compatible glue to attach the insulation to the back of the hatch.

Air Sealing the Hatch Opening

The hatch usually sits on wood trim lip that extends past the opening. Each hatch design is distinct and you will certainly need to determine the finest method to seal the trim.

Setting up Latches and Handles (Optional).

Fasten two handles to the inside of the hatch to aid in pulling it down against the weather-stripping. Install four latches on opposing sides of the hatch and trim so that when you take down on the hatch they secure it versus the compressed gasket.
