10 ways to identify quality window products and companies:
- Invest in a vinyl window that has been CSA certified and Energy Star approved. They may cost a little bit more, but you'll get your money back quickly via increased energy efficiency.
- Purchase vinyl windows that come standard with warm-edge spacer systems. Some companies offer them as an option, but how will you know what you've actually received, after the fact?
- The air space between the two panes of glass should be greater than 1/2″, but less than 7/8″, for optimal performance.
- Make sure that all of the vinyl window frames and sashes are fusion welded (not mechanically fastened, or screwed together). Vinyl doesn't hold screws very well.
- Sashes should all be interlocking. You can visually check for this when looking at the window.
- Vital parts such as the handle pulls need to be a moulded part of the window and not an add-on or snap-in piece. If they're not, they could break off and would be very difficult to repair.
- Look for vinyl windows with a “tilt-in” feature. “Lift out” windows can sometimes be slightly more energy efficient, but the sashes can also be very heavy and difficult to remove and re-install when cleaning.
- Make sure that the window is made of 100% virgin vinyl material and not reground (or recycled) vinyl. The latter can be brittle and won't last nearly as long.
- Whenever possible, buy from the manufacturer. This way, you'll avoid the finger-pointing that invariably occurs when a problem arises and each party tries to absolve itself from responsibility.
- Choose a company that's been in business for at least 10 years, with a solid reputation and a history of standing behind its customers. Remember, a warranty is only as good as the company behind it.
