Here's a list of some FAQs asked by many of customers in Alaska.
Q: What is an R-Value?

A: “R” describes thermal resistance of any particular material. This indicates how well your home blocks heat flow. When a home has good “R” value, warm air is retained in winter and kept out during the summertime.

How do I raise my R-value?

A: Adding more insulation to your home or structure will increase your "R" value and lower your energy bill.

Q: How do I choose an insulation that's right for me?

Ask yourself the following questions:

Where will the material be installed?
What environment will the insulation be exposed to?
What are my savings?

Q: Is it possible to add insulation to a finished wall?

A: Generally No, though there are exceptions. If there is little or no insulation within the wall cavity, insulation can be added.

Q: my floors are cold, will additional insulation keep them warm?

Yes. Adding insulation to your crawlspace will increase your homes ability to retain heat, thus keeping your floors warm.

I want to create a sound barrier in my home. Can I add insulation to the floors without removing the sheet rock?

Yes. Sound insulation can be added without removing sheet rock, but a small portion of the finished material must be removed.

What kind of insulation does Alas-Co use?

We use Johns Manville fiberglass, Certainteed Fiberglass, Icynene, polyurethane foam, Corbond III spray-applied foam, and Certainteed Spray-applied Foam. See our services page for more info.

What causes ice to build up on the roof?

The icicles hanging from your roof are referred to as ice dams. Ice dams are caused when the upper portion of your roof is warm and the lower portion is below freezing. Adding proper insulation and enhancing ventilation will generally solve this problem.
