How Our Unique Fibrex® Material Is Manufactured

At Renewal by Andersen®, the frames of our windows are made of our unique Fibrex® material. This composite framing material has the strength of natural wood, but with the low-maintenance benefits of vinyl. It’s also twice as strong as the latter material.     ——————————————– CONTINUE READING ——————————————–Of What Is Fibrex® Material Composed?Andersen® manufactures millions of windows each year. Milling intricate profiles in the windows produce wood pieces that are not big enough to be used in other window components. The unused wood is reclaimed and repurposed to create the Fibrex material, which is made up of 40% wood fiber by weight and 60% proprietary polymer. The wood fiber is heated to make sure it’s free from moisture. After it has been dried, the polymer is heated to a certain temperature and then combined with the wood fiber. When the right amount of pressure is applied to the liquid polymer, it encases and fills every cell of the fiber. The wood fibers then align and bend together, which allows Fibrex to resist moisture and have superior durability. After this, the compound goes through an extruder so it can be made into any shape and applied with virtually any color. What Are the Benefits of Fibrex?Fibrex can withstand extreme weather conditions and weather changes. The wood fiber helps in insulating the material to minimize heat loss in winter and heat gain in summer. Together with our special glass packages, you’ll have windows that can help make your home comfortable and save up to 25% on your energy costs. Renewal by Andersen is a window company known for its superior products and excellent workmanship.
