Windows Information
Windows are a product that receives an EnergyStar rating, so always look for the EnergyStar label if you are going "green". That said, there are some features in windows that can greatly expand their efficiency. New developments in window technology enable today's products to far outperform those of a few decades ago. Among the improvements are multiple glazing layers, low-conductivity gas fills, better seals on insulated glazing units, heat-reflective (low-emissivity or low-e) coatings, advanced weather-stripping, and new frame systems. "Glazing" refers to the pane(s) of glass within the window. Look for windows that achieve an NFRC-certified unit U-factor of 0.25 or lower. The U-factor threshold is higher (less stringent) for fiberglass, certified-wood, or recycled-content frame materials—and more stringent (lower U-factors) for vinyl because of environmental concerns with PVC.
Composite windows come in two basic types: fiberglass, and wood/plastic composite. Fiberglass has some distinct advantages over wood, vinyl, and metal for window frame and sash construction.Fiberglass frames have a hollow profile that's usually insulated with fiberglass or polyurethane foam. Because the conduction through window frames is a significant source of heat loss, insulated fiberglass frames are an attractive option. Durability of fiberglass as an exterior material is also good. Most fiberglass windows have factory-applied, baked-on coatings and can be repainted.
