Window Warping: What Is It and What Causes It?

Warping is a common problem in wood and vinyl windows. It does not only affect the curb appeal of your home, but it also decreases its overall energy efficiency and comfort. So, what is window warping, and why does it occur? Our window specialists share more information in this post.

Window Warping

What Are Warped Windows?

Warping occurs when windows begin to bend and look deformed. It creates gaps around the windows, allowing unwanted air leakage or heat transfer. Various types of window warping are:

  • Bow  Perhaps the most prevalent type of window warping, bowing occurs when the window bends along its face.
  • Crooked  This is another common type of window warping. A crooked window occurs when it bends along the edge.
  • Cup  Cupping occurs when the window warps inward or outward.
  • Twist  Twisting occurs when the edges of the unit appear twisted.

What Causes Warped Windows?

Moisture is a major reason behind warped windows. Because wood naturally absorbs and retains moisture, it is prone to warping. Changing temperatures also cause wood windows to undergo frequent contraction and expansion. When this takes place, window openings become a poor fit and can be another factor that causes bending.

A lot of other variables can influence how dramatically wood and vinyl windows warp. These include grain orientation, sunlight exposure and air circulation.
