Insulated Attic Walkway

Add weatherstripping around the perimeter and a sweep to the door of a walk up attic.

Insulated attic walkway.

There is no walkway or landing in the attic. With any attic insulation project an all important first step is to air seal the ceiling plane below at every electrical plumbing flue and duct penetration. Use a zippered insulated tent to keep the enclosure draft free attic tent at 7 attic cover insulator 120. The floor must extend beyond the insulation so that the insulation is properly covered.

If you need a second layer of batting insulation lay it perpendicular to the first layer. If you can insulate below the floors use rock wool or fiberglass batting to the depth of the floor joists. Insure there are no air leaks around plumbing vents electrical wiring or in corners. I would recommend fiberglass blown in insulation rather than cellulose because it is not conducive to insects.

The insulation is 12 15 deep. Affix rigid foam insulation to the attic side of the hatch or door. If you find leaks seal with an appropriate foam. You could also lightly spray for insects over fiberglass if needed.

The only means of traversing the attic is by walking the joists. Because of this the space is able to supporting heavy loads. I would think this could be a hazard as you would disturb the insulation might miss a step and fall through the sheetrock or trip over a hidden. Do you just wade through the insulation on your inspection.

However if you need to make it narrower i would recommend standing some unfaced blanket insulation on end along the edges of the walkway to hold the loose. Attic hatch or door. If you can make the walkway 2 wide it most likely would not be necessary. If conditioned air is seeping into the attic in winter it can condense it s moisture out in the cooler layers of the insulation sometimes to the point of dripping through onto the ceiling but it also increases the moisture content of the wood in the attic.

Pull down stair or ladder.
