Fibrex Replacement Windows
Fibrex windows are a unique product that is made by Andersen Corporation. Basically it is a composite material that is made of wood fibers mixed with copolymers or epoxy resins. The division that carriers this product line is called Renewal by Andersen and their presence in the window marketplace is to sell replacement windows, as opposed to Andersen which primarily sells to the new construction industry.
Fibrex replacement windows will not rot, or need maintenance of any kind. It is not a wood clad product so there is no natural wood at all that could deteriorate over time. In addition it can be painted and has more of a traditional wood window look than an all vinyl model. This product line is very expensive relative to all other lines that are out there and thus suffers from a reputation of being overpriced.
