For an attic with rolled fiberglass insulation, what is the proper way to perform work in the attic?
Is it okay to just walk on top of the insulation, stepping where there are beams underneath it? Or is the proper way to roll up the insulation so that you are not walking on it?
Or is there a different method?
The goal is to not reduce the insulating properties of the fiberglass insulation.
UPDATE: I attempted to write this question in a generic way to help as many people as possible, but I can now see that by doing so, I've missed the mark. My apologies. I am not the one who will be performing the work in the attic. It will be contractors who work for a third party (warranty). They claim they can just walk on top of the fiberglass insulation along the beams (and sit on it), and that it won't harm the insulation at all. I have no idea, hence this question.
So although I truly appreciate the answer suggesting cutting up wood to make walking planks, I know the contractors will never be willing to do anything like that. Basically, I'm interesting in knowing if it's fine for them to walk on top of the rolled fiberglass insulation and sit on it while they perform work, or if doing so will reduce the effectiveness of the insulation. This attic gets very extreme temperatures within it.
I don't want to make unrealistic demands of the contractors, but I also don't want the effectiveness of the insulation to be reduced.
