Insulated Attic Walkway

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.

Insulated attic walkway.

Add weatherstripping around the perimeter and a sweep to the door of a walk up attic. Pull down stair or ladder. The blown in insulation can be blown right over the ductwork. I would recommend fiberglass blown in insulation rather than cellulose because it is not conducive to insects.

Attic hatch or door. The only means of traversing the attic is by walking the joists. Do you just wade through the insulation on your inspection. This is because the horizontal chords are the strongest part of the attic.

Insure there are no air leaks around plumbing vents electrical wiring or in corners. Because of this the space is able to supporting heavy loads. There is no walkway or landing in the attic. If you find leaks seal with an appropriate foam.

Use a zippered insulated tent to keep the enclosure draft free attic tent at 7 attic cover insulator 120. 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. The insulation is 12 15 deep. If you need a second layer of batting insulation lay it perpendicular to the first layer.

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. The attic walkway is constructed so that sits above the horizontal chords of your attic. 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. If you can insulate below the floors use rock wool or fiberglass batting to the depth of the floor joists.

If you can make the walkway 2 wide it most likely would not be necessary.
