What Type Of Insulation Do I Need For My Attic
Updated: Feb 25
With so many DIY products out today and people trying to save a buck we get why people would be looking to do their own insulation however, it's not the best way to go, and hiring a professional can definitely save you a lot of headaches!
So, what type of insulation should you be using in your attic? Well, you CAN use any kind of insulation you want. There is no single solution however after our years in the business we would tell you that blown-in fiberglass insulation is the best route to go.
There are 4 main types of insulation out there that people use in their attics: batts, which are the large rolls of insulation people commonly get from the hardware store, blown-in fiberglass, blown-in cellulose, and spray foam. There are others as well but these are the most common.
Blown-in fiberglass is the only one of the 4 that really has no drawbacks to you as a homeowner though!
If you were to install your insulation with fiberglass batts from the hardware store, oftentimes people struggle to get them into tight places which results in poor insulation factors, and intern increased energy costs. If your spending money on something already, especially something that should save you money every month, why not do it right?
As for blown-in cellulose, this product is sprayed with chemicals to make it fire resistant and help prevent pests. The unfortunate this is that cellulose is extremely dusty and allows those chemicals to end up everywhere the dust lands. this dust is so fine it can get in through can lights in the ceiling, any time you open your attic access, around fans and electrical, etc. It's just, not an ideal solution.
In regards to spray foam, while it does insulate well, it also has its drawbacks. Studies have shown spray foam can release chemical gases for YEARS after it has been sprayed into a structure. I don't know about you but I don't want any chemicals floating around my home and around my children, family, and friends...
That brings us back to blow in fiberglass. The only real issue with it is that it can be itchy to install which as a homeowner having us handle the project is not a big deal. The blown-in fiberglass allows us to get hard to reach areas insulated easily by blowing the insulation back into all the nooks and crannies, it is free from pesticides and other chemicals, fire-resistant naturally (its glass..), and does not have any chance of release gases into your home since it's not a spray-applied chemical.
As you can see, blown-in fiberglass is really the BEST INSULATION available.
