Configurations & Features of Storm Windows

• 

  Measure Twice, Install Once

  To make sure your windows fit properly, measure each one separately, even if you think they're the same size. Although some windows might appear to be the same size, measuring each one individually ensures you get a proper fit every single time.

  Basement Storm Window Sizes

  Storm windows that go in the basement only have one pane, which is secured with thumb latches on the frame's exterior so you can remove it quickly. Some signs of excellent basement storm windows include pre-drilled holes for easy installation, weatherstripping for better protection from the outside elements, a stabilizer bar for extra strength, and a screen to keep bugs out if the pane is removed.
• 

  Two-Track

  With this configuration, the storm window has a screen on the bottom portion and outer pane of glass on the top portion, both of which don't slide up or down. The inside pane (located in the inside track) can be raised for fresh air. This type of storm window pairs with double hung windows. To ensure a good purchase, look for a two track window with adjustable ventilation stops on the inside track, removable glass and screen, pre-drilled holes, and quality weatherstripping.
• 

  Two-Track Slider

  The only change with this window is it opens horizontally instead of vertically, and pairs with slider windows instead of double hung windows. As well as looking for the previous features, make sure your two-tracker slider window has a stabilizer bar for extra strength.
• 

  Triple-Track

  This type of storm window features individual tracks for each pane and half-screen so each sash can move independently, allowing you to pass items through the open window. For increased cross-ventilation, the screen and both panes of glass can be moved to the top. Triple-track windows pair with double hung windows, and you should look for windows that have a removable glass and screen, pre-drilled holes, quality weatherstripping, and a stabilizer bar.
• 

  Colour Options

  Storm windows are usually available in brown, white, and mill (a silvery aluminum colour), but some manufacturers also make almond-coloured storm windows. Find the right colour to complement your home's décor.
• 

  Security

  Look for things like reinforced screens, extra durability, multi-point locks, and panel clips that can help your storm windows withstand forced entry attempts. This can help keep you safer without having to install bars on the windows.
• 

  Low-E Glass

  Low-Emissive (Low-E) glass has been treated with an invisible metal or metallic oxide coating, which provides superior energy efficiency by reflecting heat but still allowing light to pass through.
• 

  Utility Windows

  Even though storm windows for sheds (called utility windows) might not be as important as the ones on the house, it's still important to choose quality windows with strong, airtight corners. Look for corner joints that overlap for better insulation, and skip windows where the corners are mitered.
