Are Vinyl Windows a Good Choice for My Home?
While vinyl windows are extremely popular these days, they aren’t necessarily the best choice for homeowners in parts of the country with extreme summer heat (Houston). The reason? Vinyl windows are very susceptible to bowing and warping-particularly large windows that are exposed to hours of direct sun exposure. As you can see from the photos below, vinyl windows are particularly prone to sagging at the head and crowning at the sill. Why is this a big problem? Because when vinyl
window begins to change shape, they will leak copious amounts of air, thereby reducing their energy efficiency dramatically. Even worse, bowing vinyl windows often allow water infiltration which can damage your walls and floors.
Great alternative frame materials are thermally-broken aluminum, composites, or fiberglass. All three of these materials are much stronger than vinyl, and can withstand the Houston summer heat better than any vinyl window. If you intend to remain in your home for more than 8 years, choosing a product with better longevity and durability will prove to be a better investment over the long term.
