There are a couple of reasons why windows can fail–and one of the most common is warping. This problem, which tends to happen more often to wood and vinyl windows, is usually caused by heat and moisture damage. You’ll know a window has become warped because its frame will be crooked, twisted, or bent out of shape. But how exactly do you prevent this? That’s an easy question with an equally simple answer: investing in Fibrex® replacement windows offered by Renewal by Andersen® of Portland.

Why Fibrex®?
They are your warp-resistant alternative to wood and vinyl windows. Fibrex combines the strength and insulating properties of wood with the low-maintenance performance of vinyl. Compared to other window materials, it’s more impervious to warping. Here’s why:
- Fibrex is made of reclaimed wood fibers and polymers, meaning it doesn’t have the same weaknesses as wood. Since this material doesn’t absorb and retain moisture, our replacement windows are less susceptible to mold and rot–factors that contribute to warping.
- Unlike vinyl, this advanced composite doesn’t expand or contract as much when exposed to extreme changes in weather and temperature. Your windows will retain their shape, keeping them sturdy and long-lasting. What’s more, Fibrex can effectively resist cracking, pitting, and corrosion. The toughness of the material allows for windows with a stronger, airtight seal helping prevent considerable energy loss.
