Replacing Attic Door Insulation Replacing Attic Door Insulation

The most common attic door insulation is a cover to keep heat from going to the roof. This cover can get ripped or broken, though, in which case it should be replaced. Replacing it yourself is much easier and more affordable than many people think. With a few tools and materials, you can do it.

Step 1—Clean the Attic Frame

First, clean the attic doorframe and remove the old insulation. Clean the frame surface thoroughly to avoid having debris get in the way of your job.

Step 2—Measure the Attic Stair Frame

Use the measuring tape to take exact measurements of the attic doorframe. Take care here, because if your calculations are incorrect, your insulation will not fit over the door, and all your hard work will have been for nothing.

Step 3—Cut the Foam Board

Now that you have all the measurements, create a cover with a box shape. Grab your utility knife and straight edge and use them to cut five pieces to make four sides and a top.

Step 4—Put the Pieces Together

Once you have all the pieces, use the foil tape to put them together. When it is finished, it will look like a box without a top.

Step 5—Seal the Attic

Finally, use weather stripping to seal the surfaces in contact between the cover and the attic.
