Evaluating a Window’s Performance in 3 Easy Steps:
STEP 1: Examine the thermal performance of the ENTIRE window
U Factor: Thermal Insulation The U Factor indicates how easily heat will flow through the window, whereas R Factor indicates the opposite, how well the window will resist heat flow. The lower the U Factor, the better a window insulates.
Solar Heat Gain Coefficient (SHGC): The amount of solar radiation admitted through a window. The lower a window’s SHGC, the less solar heat is transmitted into the house and the easier it is to keep your house cool in summer. On the other hand, in northern climates, a higher SHGC can provide beneficial passive solar heating in the winter. Signature offers a variety of high performance Low E glass packages with varying SHGC ratings to suit your needs, based on your climate.
Visible Transmittance (VT): Measures the percentage of visible light that is admitted through the window. High performance glass packages have been designed to enhance a window’s thermal performance by blocking ultraviolet and infrared light, while maximizing visible light transmission. Clear glass itself blocks about 20% of visible light.
STEP 2: Check the structural performance of the ENTIRE window
Signature windows are tested to standards set forth by the American Architectural Manufacturer’s Association (AAMA) for structural performance. Air infiltration, water penetration, and structural wind loads are three commonly referenced tests.
What Is Air Infiltration? The amount of air that passes through the seals of a window’s operating sashes per minute, per square foot of window. Using a typical vinyl window would be like having a hole in the wall of your home, leaking 9.68 balloons worth of air per minute!
Signature windows are over 10 times more air tight than typical vinyl windows.
STEP 3: Verify the thermal performance of the glass
Super Spacer® Signature Windows:
Use advanced Super Spacer® as a standard to create insulated glass with a warm edge around the perimeter. The edge of the glass is typically the coldest spot on the window and can be prone to condensation. Other windows utilize glass panes with rectangular aluminum that conducts the heat away from the inner pane of glass, resulting in a cold edge. Super Spacer is a non-metallic, structural foam spacer. Super Spacer® blocks heat escape, dramatically reduces condensation, and offsets the effects of temperature changes that prevent stress cracks. This “Health Smart® Spacer” significantly reduces the opportunity for mold and mildew to form on the window.
Microshield: Signature’s MicroShield triple antimicrobial weather– stripping maintains a weather tight fit between the sashes and frame. It keeps mold and mildew at bay, and is especially helpful for people with allergies and asthma. This completes the package for a truly “Health Smart®” window.
