Which Insulation is best for attics?

There are a few factors that come into play when selecting the right insulation material. The climate or location you live in, Rvalue and cost are all important factors when choosing the right product.

For example, R-value can be affected by thickness and density of material and location of installation. Cost may play a huge factor to whether you are on a budget or prefer Quality(no matter the price) . It’s always a great idea to take the factors that I mentioned and decipher on which insulation below would work best for you!

Spray Foam Insulation: The R-value is about 3.5 per inch and is overall a great option for attics. It may be slightly more expensive than the other options listed, but since it provides excellent moisture control and provides outstanding results, foam insulation may be worth the investment in the long run.
Batt insulation remains to be one of the best for attic insulation. Batt usually comes in pre cut sections and is known to fit snugly in between joists and and stud spaces. Particularly, Fiberglass batt is a great option and will be that barrier needed to keep you warm in the winter times.

How Long Does Attic Insulation Last?

If you go into your attic and notice that there are critters, any ice dams during the cold season, if there is any shifting in the existing insulation then it might be time to call a professional so they can give you a clear evaluation on the status of your attic. Let’s start off by checking what each insulation’s time span is. Each insulation may differ in lifespan and it’s beneficial to know the differences.

Fiberglass: this lasts typically for 80-100 years which seems like a great investment if you ask me. However, although it may last that long, it’s a good idea to get it checked out and replaced every 15-20 years.

Cellulose: This is a more environmentally friendly option since it is made out of recycled materials. However, since it is made out of reused materials then it does have a shorter lifespan than Fiberglass. It can last up to 30 years but usually lasts half of that because it is so vulnerable to mildew and pests over time.

Spray Foam: This lasts practically forever making it worth every penny. If it does become damaged for whatever reason such as through being punctured or on fire, then it will need to be replaced.
