In Maryland, the homeowners learned that water could easily damage insulation, making it less effective by lessening its R-factor. The R-factor is the insulation's ability to keep heat in during the winter, and heat out during the summer. It is listed right on the insulation: the higher the number, the better it works as a barrier. Generally, the higher the R-factor, the thicker and more energy efficient the insulation.
Exterior walls will usually use insulation with an R-factor of 13, floors and crawl spaces R-19, attics will use R-30 or higher. Rolled insulation should maintain its R-factor for a lifetime, if it's installed properly. To keep your R up to par, here are a few tips:
- When installing insulation, fill in all the gaps to maintain a consistent R-factor.
- Avoid packing down insulation. It will crush the air pockets and lower the R-factor.
- Contact your local utility company or a licensed professional if you're unsure which R-factor insulation to use in a particular location.
Insulation with the proper R-factor will keep your home warmer in winter, cooler in summer and your wallet fatter year round!
