Storm windows are a great insulator and a great value for making your home more energy efficient. A high quality storm window with an air infiltration rate of 0.20 or lower, when installed over your existing window, can perform equal to the energy saving performance of many replacement window products, at a fraction of the cost. Exterior storm windows also protect your prime window from the elements, reducing painting and puttying maintenance costs.
When reducing heat loss, eliminating drafts and conserving your original windows are important to you, storm windows are the perfect solution.
Exterior Storm Windows
Our double hung combination triple track storm window has one of the best air infiltration rates in the industry. The double weather-stripped frames and rigid interlocking center bar keeps drafts out and heat in. Includes an operable locking screen. The sash and screen on this window can be removed from the inside for cleaning. Available in white, almond, dark bronze and black.
The sliding storm window also has an exceptional air infiltration rate. At 0.11 cfm/ft, we don’t know of any other sliding storm window made as tight as this one. It comes with a removable half screen and optional full screen. We also use this window in 3-Season Enclosures because of its air tightness, strength, and full screen capability. The sash and screen on the sliding storm window can be removed from the inside for cleaning. Available in white, almond and dark bronze.
The picture window storm window has a master frame that is sealed in place and a sash that can be easily removed from the outside for cleaning. Available in white, almond, dark bronze and black.
Deadlite storm windows are used over existing prime window deadlites, or in situations where the crack space of an existing operable window will be completely covered, virtually eliminating air infiltration. Deadlite storm windows are direct screwed in place to the existing window frame and are not advised in applications where the storm window will be removed on a regular basis. Typical applications for deadlite storm windows are at entry door sidelites and some picture window applications. Available in white, almond, dark bronze and black.
Interior Storm Windows
Interior deadlite storm windows are perhaps the most energy saving and cost effective measure there is. The interior storm panel is installed on the inside of the home, covering the entire opening of the prime window, virtually eliminating air infiltration from in or out.
On homes that already have an exterior storm window, adding an interior storm panel will triple glaze your window, adding an additional insulating dead air space on the inside, making the window draft free and extremely energy efficient.
Interior storm panels are installed with clips or magnetic strips for easy removal. The magnetic panels are perfectly suited for inside installation in homes that have steel windows, typically found in the tudor style homes of the Newton and Brookline areas, or the contemporary style homes of Lexington and Lincoln.
Interior storm panels are available in white, almond and dark bronze.
Our storm windows have the option of being glazed in Low-E, obscure, acrylic, Lexan, or tempered glass.
About Air Infiltration
When a storm window is installed over an existing window, the air space between the two windows becomes ‘dead air’, which acts as an insulating barrier by reducing air infiltration and heat transfer.
Air infiltration is the amount of air leakage in and out of a home through cracks in walls, windows and doors. Although air leakage occurs in many areas of a home, most air leakage occurs through windows.
Storm windows are measured for air infiltration rates and expressed in units of cubic feet per minute per square foot of window area (cfm/ft), usually at a specific pressure that represents a 25 mph wind velocity. The lower the air infiltration rate of a window, the less amount of air traveling through the window, resulting in reduced heat loss and drafts.
At North Star-Bailey Company, our high quality storm products have extremely low air infiltration rates that are among the leaders in the industry today.
