is there some cheaper materials that can be used to insulate a garage instead of using fiberglass? and how?

Answer 1

I used card board boxes and plastic sheeting.It works grear but is a fire hazzard so be careful.

Answer 2

Asbestos is gray to gray-white and in the form used for insulation is more dense than fiberglass and fairly friable, hence the danger of airborne fibers, which are a significant carcinogen. The pink fibers are undoubtedly fiberglass, which, at worse, are usually no more than an irritant. The structure of asbestos particles is like a rod with many barbs which prevent it from becoming dislodged from the lungs, leading to asbestoses. Fiberglass, in contrast is a smooth fiber that usually doesn't remain in place after inhalation. Asbestos has been banned in most applications since at least 1975, so if your construction is subsequent to then, it is most assuredly not asbestos.

Answer 3

Unless you go to the old fashion way of nailing newspapers up between the studs, fiberglass is the best of insulators.

Answer 4

The best R (insulation) factor for your dollar will come from fiberglass.

Answer 5

Putting up foam sheathing board inside is much cheaper that insulation batts. It is much safer than paper or cardboard.
