Why Fiberglass?
Why is fiberglass superior to other products like steel, aluminum, vinyl or wood?
Consumer's Guide says: "The best energy performance in window frames has been achieved using a fiberglass frame with foam insulation in the frame cavities. Frames can have a significant effect on solar gains (and the ER rating). Stronger materials that allow narrow frames and sashes like fiberglass allow more glass area and more solar gain".

Fiberglass is also the most compatible material to use with glass. The expansion and contraction characteristics of glass and fiberglass are almost identical. The glass (glazing) and frame expand and contract together.
Offering more insulating value than even its closest competitor – wood – fiberglass is stronger and more durable. Another advantage of fiberglass is that fiberglass frames have a baked-on enamel coating to provide a low maintenance finish.
Accurate Dorwin's fiberglass frames offer strength. And when combined with foam insulation, Accurate Dorwin windows offer the ultimate in energy efficient window frames.
