Addressing Warping Issues With the Andersen® Fibrex® Windows

Even with today’s modern and durable vinyl windows, warping is still a common issue. Despite their popularity (these windows account for more than half of the market share of residential window sales), vinyl windows are far from perfect. This is why as a leading window company, Renewal by Andersen®, has made it its mission to find a more suitable material that can withstand warping as well as other issues plaguing other common window materials.  

Addressing Warping Issues With the Andersen® Fibrex® Windows

What Causes Windows to Warp?

There are many reasons why a vinyl window might warp, but in the majority of cases, the main culprit is moisture buildup. Vinyl windows tend to absorb moisture. When too much moisture is absorbed unevenly, it can cause those sections to shrink and expand. 

The Benefits of Installing the Andersen® Fibrex® Windows

Renewal by Andersen’s Fibrex® material is a composite made with wood fibers and polymer. What makes it so great is that it has the strength and durability of wood while still retaining the low-maintenance properties of vinyl. 

It is an extruded material that can be crafted into virtually any profile for doors and windows while being completely warp-resistant. In addition to it being warp-resistant, Fibrex is also warranted not to peel, crack or fade within its expected lifespan. Lastly, Fibrex window frames are extremely energy-efficient. When paired with our High-Performance Low-E4® glass, you are sure to save a significant amount of money on your heating and cooling bills.
