I want to add R-30 insulation to my attic. So far I used only JM fiberglass insulation from HD or Lowes. Since now adding attic insulation will cost me approximately $1000 at least I want to shop a little bit to see if I can save something. Are there any other brands that manufacture fiberglass insulation and are worth considering? Are HD or Lowes the best place to buy fiberglass insulation? JM insulation is formaldehyde-free? How important is it? Do other manufacturers use formaldehyde in their fiberglass batts?
