Tips to Think About, Ideas to Ponder before Buying

Window frames are available in a variety of materials, including aluminum, wood, vinyl, and fiberglass.
When purchasing windows you can get single pane, double pane or triple pane. Triple is the "ONLY" window the Department of Energy allows in it R-5 Volume Window Program with a U Value of .22 or less.
If purchasing more than one pane you will be offered the opportunity of filling the void between the panes with either argon, krypton or the new zeon gas to increase energy efficiency.
Multi pane windows require a “spacer” which holds the panes together and is critical to keeping the gas in and moisture out. There are several different types of varying quality and often you can upgrade to a better one. Thermal Plastic is best.
Always ask the company providing you a quote about disposing of the old windows.
Vinyl window frames can be mechanically fastened, i.e. screwed together at the corners, or welded. Always use welded master framed windows.
Manufacturer's Warranties are very important, READ THEM.
Never try doing this project ourself, buying the best window made in America means nothing if it is not installed by an experienced factory trained installer.
When replacing all the windows in a two story home, installation should start with the furthest window from the door the men are using and the last window installed is closest to that door the men are using. Always working there way out of the home.
