Master Builder Matt Risinger reveals another one of his favorite things in this review of Marvin Integrity Windows. In a remodel project with architect Nick Deaver, Risinger uses the "Wood-Ultrex" line of windows.These fiberglass windows are not only durable, they're also great for the efficiency of your home; they keep elements out of your house to stay warm in the winters and cool in the summers.If you're worried about how the fiberglass looks, look no further. The inside is clad with wood to give you the look of a wood window at a much better price. Even more, these windows are much nicer than the vinyl or aluminum options.Whether you're working on a new home or a remodel, consider the Marvin Integrity line. Want to learn more?
