Vinyl Window frames are wide because vinyl is not as strong as other materials, it must be beefed up in order to hold up. This is particularly true in extreme environments. In extremely cold climates, vinyl can be prone to cracking. In extremely hot climates, vinyl is prone to bowing and warping. Vinyl window manufacturers enhance the strength of their windows by using thicker vinyl walls and by honeycombing the frames with multiple chambers – both of which lead to wider frames.
Because Houston homeowners are partial to narrower window frames, they are often tempted to purchase vinyl windows with narrower frames, never stopping to think about the fact that they are getting flimsy windows that will not stand the test of time. While they may look good, they won’t perform well and that makes them a poor investment.
For narrower frames without compromising strength, rigidity, and longevity, we recommend considering Ultra Aluminum Replacement Windows or Ultra fiberglass windows. Taking your time to consider the options – prior to purchase, is the key to long-term satisfaction with your new windows.
