I just moved into a house made in 1969, it gets really hot during the sunny days and cold during the winter. I'm living close to the rocky mountains just so you have an idea how cold and hot it gets. I then got a contractor to let me know what was the problem and told me that I have about 6 inches of fiberglass insulation in my attic and that I need to have about 15 inches.
He told me the next process is to add insulation with a blower machine and then I could add the needed insulation to solve the problem. I looked online to see how easy/hard is to do that and I found out that it's not an easy job, and of course not pretty cheap. I was planning to do it myself to save some dollars but I'm pretty sure that the current insulation in the attic might have some asbestos, so I just don't want to deal with that.
Then I was looking for alternatives to insulation and I found the reflective insulation to be an effective way (it claims that it can get the temperature down to up to 10 degrees) to insulate a home with a possibility of doing it without having to hire a contractor for the job.
First question here:
If is that effective, cheap and easier to install than other methods is that great as they clam it to be? It sounds good to be true.
After watching some youtube videos on how to install this kind of insulation, I noticed that when you install it inside your attic on the ceiling of it, there will be a gap between the ceiling and the reflective layer, since it has be stapled to the studs, so I was wondering how hot could that get and if would affect the roof in any way?
