Insulated Attic Walkway

Because of this the space is able to supporting heavy loads.

Insulated attic walkway. 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. The attic walkway is constructed so that sits above the horizontal chords of your 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.

There is no walkway or landing in the attic. Pull down stair or ladder. The insulation is 12 15 deep. The only means of traversing the attic is by walking the joists.

Insure there are no air leaks around plumbing vents electrical wiring or in corners. Attic hatch or door. The floor must extend beyond the insulation so that the insulation is properly covered. You could also lightly spray for insects over fiberglass if needed.

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

If you need a second layer of batting insulation lay it perpendicular to the first layer. Use a zippered insulated tent to keep the enclosure draft free attic tent at 7 attic cover insulator 120. This is because the horizontal chords are the strongest part of the attic. If you find leaks seal with an appropriate foam.

I would recommend fiberglass blown in insulation rather than cellulose because it is not conducive to insects.
