Vinyl replacement windows are an inexpensive and durable alternative to wood or metal windows. A generation ago, vinyl windows had problems with thermal expansion: the sash would expand or contract at a different rate than the glass, causing leakage. But huge steps in technology have allayed those fears. Today, vinyl windows are a favorite among building contractors and homeowners looking for an inexpensive, yet effective, alternative to wood and metal.
Why Vinyl Replacement Windows?
Vinyl replacement windows are made from PVC, polyvinyl chloride, a plastic that is often used by builders to imitate the look of wood. Most likely, if you are in a new home, your moldings are made from this same material. And unless you are inspecting it closely, you would never know the difference between wood and vinyl. The benefits of this material are enormous. You will notice that because the vinyl does not warp or settle as much, your home heating costs will go down. Similarly, your home maintenance costs will go down. But equally important, most woods do not last lifetimes. We coat them in chemicals, paint, and more in order to protect wood from the elements, but unless it is hard old growth wood (which is difficult to find these days), the wood will eventually rot and need to be replaced.
Maintenance Free
Aside from washing your windows, there aren't as many general home maintenance duties associated with vinyl. The material resists corrosion, warping, water damage, and everything else that plagues wood. And because vinyl is colored in the factory rather than painted, the color goes all the way through, making dings and scratches unnoticeable. This provides you with a low maintenance product for a typically high maintenance part of your house. This addition greatly reduces home maintenance costs and time.
Some Vinyl Windows Concerns
While technology has taken great strides, it is still important to do your research on the different brands out there. While problems with thermal expansion are hardly a concern anymore, it is still important to make sure you are using a reputable, well-respected manufacturer. This should leave you with only one potential concern: aesthetics. Vinyl is plastic. And because it is colored in the factory, it is not painted, adding to the different look. Most people never notice. Vinyl is increasingly replacing wood in people's trim, sashes and windows for a reason. They like the price and the visual difference is only noticeable if you are aware of it and look for it, but as always, it is still something worth investigating yourself by looking at a home with vinyl windows.
If you choose to install vinyl, you will find that they provide many strong advantages over wood. Vinyl windows not only cost less, but the day-to-day maintenance will cost you less over the years. You will find yourself spending less time worrying about something as simple as your windowsand what can be better than that?
