Glossary of Common Window & Door Terms
Here are some of the more common terms used in the window and door industry.
Windows and Patio Doors: Vinyl vs. Wood
Keep the following things in mind when choosing your new windows. If you’re still having trouble deciding, contact your local WI Services sales associate for advice. They’re factory-trained window and door experts!
Vinyl Windows
Vinyl windows and patio doors are typically made from PVC (polyvinyl chloride), and provide very good energy savings. For the budget minded consumer, they offer a great value in price versus performance. Available in standard sizes, they're also available in custom sizes and shapes. Vinyl is maintenance-free, since the vinyl color goes all the way through. They never need painting or touch-ups, since nicks and scratches don’t show a different color. For all these reasons, vinyl windows are popular for direct replacement window applications.
Wood Windows
Wood windows offer exceptional energy savings, and come in an almost endless variety of standard sizes and shapes. Custom sizes and shapes are also available. A number of different exterior and interior coating options (cladding) are available that make them virtually maintenance-free. Wood windows are the choice when you need to match existing windows, and will add more resale value to your home than vinyl windows.

Steel doors are strong and secure, and are the choice when you want maximum durablility and efficiency without sacrificing styling and affordability. Built-in protection from rust and corrosion means these doors will last for years.
