While wood, vinyl and aluminum windows have a tendency to warp and crack, Renewal by Andersen’s exclusive Fibrex® composite material is made from reclaimed wood fiber blended with a polymer for lasting weatherproof windows. Fibrex® is warranted not to flake, rust, blister, peel, crack, pit or corrode even after 20 years*. This frame material combines the strength and insulation of wood with the low maintenance feature of vinyl to create a superior product.
Unlike other window companies that don’t practice responsible stewardship, Renewal by Andersen products are created through a sustainable, ecofriendly process that leaves minimal impact on the environment. In fact, thanks in large part to Fibrex® material, Renewal by Andersen and its parent company Andersen Corporation are one of the first window manufacturers in the world to be Green Seal Certified.
