Andersen Fibrex Windows vs. Vinyl Windows Comparison


Just after the reign of aluminum windows in the 1960s, it was thought that vinyl windows (polyvinylchloride or PVC) would be the subsequent ideal point, eternally. Plastics introduced the guarantee of windows that hardly ever experienced to be maintained: no scraping, no painting. And although vinyl is nevertheless a vastly preferred content for generating low cost, efficient windows, a single sector chief, Andersen Windows, reduces its use of vinyl. Instead, Andersen favors the use of a proprietary composite called Fibrex. Due to the fact Fibrex is a price-position competitor with vinyl, how do the two materials evaluate in client-degree substitution and new-construction windows?

What Are Fibrex Windows? 

Fibrex is Andersen’s patented PVC-wooden composite content that it works by using for a the greater part of its windows as a structural member. By bodyweight, Fibrex is composed of 40-percent recycled Ponderosa pine wooden fibers and 60-percent polyvinylchloride. Fibrex was originally made to decrease Andersen’s expenses by reusing sawdust obtained from the manufacturing of its wood windows. One problem of exposed wooden is rot. However, because each individual of Fibrex’s wooden fibers is surrounded and coated with PVC, it rots at a far slower amount than pure wooden.

In developing Fibrex, Andersen sought a fiberglass-like products that could be extruded (extruding suggests to thrust a smooth substance through a shaping filter) or injection molded. Fiberglass are unable to be extruded or injection-molded, resulting in more simple strains and shapes.

What Is Injection Molding?

Injection molding is a system in which molten content is injected into a specifically designed mould to build sections of products. Many components can be formed this way, like metals, eyeglasses, and plastics. 

Fibrex is found in Andersen’s 100 Collection, A-Collection, and Renewal by Andersen traces. Andersen has been gradually exiting the the greater part-PVC window market place for several years. At one time, Andersen owned Silverline, which Andersen bought exclusively to obtain a foothold in the vinyl window sector that was marketed in 2018. Andersen also owned the do-it-oneself vinyl substitute window corporation American Craftsman, discovered at Household Depot. Andersen divested alone from American Craftsman in 2018 in the exact same sale to Ply Gem. Renewal by Andersen remains as Andersen’s only substitution window device.

Fibrex vs. Vinyl Windows Comparison

Insulating Properties

Andersen states that “Fibrex material has remarkable thermal insulating homes” in comparison to aluminum window frames, which “conduct warmth and cold.” Independently, each statements are correct. Aluminum towards Fibrex might not be a beneficial comparison, however, considering that window purchasers considering Fibrex are normally wanting at vinyl or even fiberglass windows, not aluminum. 

Extra importantly, at a thermal conductivity rating of more than .60, aluminum is a hugely thermally conductive materials (compared to Fibrex, which has a score of about .15). A more correct comparison to Fibrex is vinyl. Internal provide sheets supplied to Andersen salespeople even state that Fibrex’s “insulating properties can be place on par with pine or vinyl.”

Heat Distortion Position

1 problem with vinyl windows, especially darker color vinyl, is sagging, bowing, and other deflection when subjected to significant heat. Andersen states that Fibrex stands up greater from heat distortion than vinyl. Fibrex’s heat distortion threshold is 173 F, in comparison to vinyl’s threshold of 163 F. So, even however Fibrex’s threshold is 10 levels bigger than that of vinyl, the two products continue being beneath the distortion setting up issue of 180 F.

Thermal Growth

Mainly because pine has a small thermal expansion charge, these wood fibers help to command Fibrex’s total expansion amount. As these, vinyl expands at additional than two times the charge (4.) when compared to Fibrex’s rate (1.6).

Compressive Energy

Andersen’s claim that Fibrex is 2 times as solid as vinyl is legitimate, but only in phrases of compressive strength. The benefit is not so a lot that you get a more robust window but that the window frame is slimmer, ensuing in far more glazing. More glazing delivers additional gentle into your dwelling.

Environmentally friendly Advantages

Wood is less costly than vinyl, primarily when that wood is recycled from another operation. It is no miscalculation that Fibrex’s patent software refers to the wood as “filler.” Fibrex positive aspects Andersen mainly because the corporation utilizes byproducts of its wood window output for all of the wooden fiber used in Fibrex. In essence, Andersen gets free products out of the deal. Some vinyl is recycled from the creation of Andersen vinyl cladding, way too. But because Andersen provides so couple of vinyl clad windows, it wants to complement with virgin vinyl. 

Even though Andersen’s growth of Fibrex advantages the corporation, it also added benefits the setting. Any stop solution that uses waste products and solutions can be viewed as eco-friendly. Andersen’s reuse of wooden fibers is specially helpful because not all of this is cleanse wooden dust. Much of it contains adhesives, paint, primer, anti-fungal brokers, and a host of other contaminants. So, trying to keep the wooden dust out of landfills or incinerators means trying to keep these contaminants out of the earth and atmosphere.
