The Different Types of Insulation

TAP, which is a type of insulation, in an attic

When the temperatures are high or low, we count on insulation to help us be comfortable in our homes. It’s important to learn how insulation works and what type suits your specific situation best.

The first thing to know is that insulation has an R-value. This measures how resistant the insulation is to heat flow. The higher the R-value, the more resistant the material is to heat transfer. The recommended R-value varies according to where you live, the type of insulation you have and its thickness and density.

Typically the higher the R-value, the better the climate control and energy efficiency. Most homes have insulation in the attic and under floors that are above unfinished basements or crawl spaces. It is most effective when placed along exterior walls and basement walls. It can also be helpful to add insulation to attics and crawl spaces. Regardless, it doesn’t matter if your home is … Read Full Post »
