What Is R-Value and What Does It Mean To You?

R-value of building insulation

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…

Fiberglass Windows Are More Energy Efficient

For making energy efficient windows, fiberglass composites offer many advantages over wood, aluminum and vinyl. Wood warps and rots over time, allowing air infiltration that undermines the insulating power of the glass. Aluminum conducts heat and cold into the interior of buildings. And vinyl can weaken with age leading to a breakdown in insulating power. Fiberglass…
