Understanding Insulation Ratings and R-Values

Insulation is given an R-value which represents the thermal resistance to conductive heat flow. If your home's current insulation has a low R-value, then you are likely losing money each time you pay your energy bill. Improved insulation in your home is the best way to help save on energy costs.

The table below provides a look at the typical rating for specific types of insulation.

    We had our crawl space sealed by a pest control company last year, but we had many problems and did not trust them to fix the problem. So, I got a total of 4 estimates from other companies and your company was by far the most informative and professional of them all. The crew was great.
