My house was built in 1982 in Clear lake area–attic insulation was 4 inches rolled between rafters–seems about 2 or 3 inches now. I need more insulation for summer heat. What is best–spray in? And how much? Any recommendations for type, insulation and contractors?
Tom: Spraying is fine. In fact, I just did my house, and I bit the bullet and decided, you know what, I’ve got to bring it up to today’s standards. It came out wonderful, and what I used, and what I would recommend others to use, is a blown in, I wouldn’t call it a spray in. Spray in is more of a foam technology.
Charlie: I want to make sure we’re clear on that.
Tom: A blown in is when you do a loose filled blown in across the floor of the attic. A blown in, formaldehyde free fiberglass would be easy, not as expensive as people think. It’s very affordable compared to all of them, and it’s the best product. It won’t deteriorate, over time, like the old product he had in his attic did.
