Is foam insulation better than fiberglass? Spray foam insulation fills all spaces, preventing air from escaping. It acts as an air barrier. Like cellulose insulation, spray foam insulation is significantly more efficient than fiberglass and has a higher R-value.
Can I spray foam insulation myself?
A: Tom Silva replies: Spray foam is great insulation, but it's fairly demanding to apply; the kit instructions have to be followed exactly. In fact, study them before you buy your kit so you know what you're in for. As with spray-foam kits, protect yourself and the floor from the dripping globs of canned foam.

Can you insulate a house with Aerogel?
Aerogel is made by removing liquid from gels, resulting in a material that's over 90 percent air and four times more efficient than fiberglass or foam. Contractors are already using the new aerogels to insulate homes that are sealed from the outside, both over masonry and under shingles, Ceramics.org reports.
What is the cheapest insulation material?
Fiberglass batts are typically the cheapest insulation, but a loose corner or tear can diminish the insulation quality.
What is the lightest insulation?
Ultra-Thin Super Insulation with Aerogel. Despite the fact that we are now living in the 21st century, aerogel insulation seems like a material out of science-fiction. It is the lightest solid known, although by volume it is 99% air. It is breathable, but it doesn't absorb water.
