What Is R-Value? Simply put, R-value is a measurement of how insulating a building material is, protecting one side from the heat or cold on the other side. A higher R-value means that a material insulates better than one with a lower value. In order to get an idea of what these values are, here […]
Improvements in window technology can result in windows with insulating power as high as R-20. But most of the heat gained or loss still goes through the frame itself.
Alexander Kolbe, co-owner of ecoDOMUS, an architectural firm that specializes in prefab construction to build green homes that are highly energy efficient, says that, “Given the choice of spending a sizable sum of money for a home that consumes energy at an alarming rate, or spending slightly more initially to benefit from substantially lower utility […]
