Air Leakage

Here at The Window Man we pride ourselves on being the Educational Window Company. We start the educational process by talking about the three Window Evils.

1 Air Infiltration 60%
2 Radiant Heat 30%
2 Conduction/Convection 10%

Today we're going to talk about air infiltration, also called or air leakage.

Air leakage is unwanted amounts of outside air entering the house through cracks and small openings. A leaky house allows moisture, dust and allergens into your home, making it unhealthy. As air pressure changes in your home, these same leaks also allow heated or cooled air to escape. These air leaks waste energy dollars! Air infiltration causes cold drafts and temperature differences within a room, which frequently causes the thermostat to be set higher or lower, so that the average temperature is at the desired level. The Window Man takes pride in only selling windows that far exceed industry standards to reduce the air infiltration into your home.

Air leakage may come from gaps and cracks around the windows and doors in your home and can account for 50% of your heating costs. By reducing air infiltration, you can use lower thermostat settings and your comfort level significantly increases.

A good analogy is to think of going outside on a cold, windy day wearing an expensive, good quality winter coat all decked out with thermal fleece and water repellent, but if you don’t zip it up, you get little of the benefits you paid for.

Choose a window that has been tested and AAMA certified for air infiltration. If a manufacturer elects to have its product tested, it cannot have more than 0.3 cfm/ft2 of air leakage per linear foot of crack space.

Vinyl is the most popular material windows are made from, but vinyl moves! Vinyl expands and contracts 10 times more then other window materials and windows are tested at normal room temperatures. Our experience shows that vinyl windows need to be tested at “.10” cfm or less, which is 3 times better than a passing grade so they don’t become drafty in the winter when they shrink.

Optium's SC7650 Series

The Window Man is pleased to carry Optimum's steel vertical sliding windows. Optimum's SC7650 Series carry either an MEA and or Underwriters Laboratories, Inc. (UL) label for fire resistance rating of 45 minutes, in accordance with the standards for Fire Tests of Window Assemblies, ANSI/ UL9 (NFPA 257, ASTM El63).

Sliding sash panels have EPDM gaskets throughout the entire perimeter (unless otherwise noted).

All units are reasonably free from scratches and blemishes and have the following:

* Zinc Coating (ASTM A525 Z200) on both surfaces, applied by a continuous hot dipped process (The Sendzimir System), followed by a "skin pass" (smoothing) procedure which eliminates roughness.
* Primer consisting of epoxy-ureic paint, applied at a thickness of 5 microns on both surfaces.>
* Baked polyester powder coating, (baked at 180-200 degrees C for 18-20 minutes) with an average thickness of 80 microns.

Windows are factory glazed with obscure or clear 1/4" wire glass. Lites have a minimum of 24 gauge wire with a maximum mesh size of one square inch as per Underwriters Laboratories requirements. Individual lites of glass shall not exceed a daylite dimension of 895 square inches each. Glass complies with ANSI Z97.l and ASTM C1036.

Frame are formed from 20 gauge steel sections, with corners which are mechanically assembled and reinforced. Sash members are 20 gauge formed sections which are coped and assembled. Corner joints are fully scaled to prevent leakage. Horizontal muntins, when required, consist of two sections of 20 gauge forming an "H" Section.
