Purchasing new doors and windows for a building can put a big dent in the bottom line. Ensuring that you purchase the most appropriate doors and windows for your needs is vital to keeping the long term costs minimized.
One way that you can ensure you purchase the right products is to understand all of the terms used in the window and door industry. Features such as kerfs and moisture barriers may leave you with a puzzled look on your face. However, these terms aren't as complicated as they seem.
Casement windowA casement window is a style of window common in historic buildings. Unlike the windows of today, casement windows are hinged on the side, which enables them to swing either inward, outward or both.
High security doorsA high security door is a door that looks like any door but is made with steel or other heavy, hard to penetrate materials. Some high security doors have special reinforcements near the locks and edges of the doors.
KerfA kerf is the area in which weather stripping is applied inside a door or window. This area is usually cut out of the door frame with a router or saw.
Heat loss caused by infiltrationHeat loss caused by infiltration is the way indoor climates are affected by changes in insulation. This includes drafty doors and windows, opening doors and windows and cracks in frames and sashes of windows and doors.
Low-emissivity coatings (Low-E)The terms low-emissivity coatings or Low-E coatings refer to special coatings applied to windows to help block heat from entering a room through the window. This can improve the energy efficiency of a building because heat transfer is minimized.
Moisture barrier, vapor barrierA moisture barrier, or vapor barrier, is created by inserting a material such as polyurethane sheeting into a window or door to help stop moisture from moving from one space to another.
US Department of Energy website offers information on vapor barriers. You can even find information on installing moisture barriers on this website.
