Window Jargon Translation Guide

Imagine yourself walking into a store that only sells black sweaters but the price ranges anywhere from $10 to $200.  They seemingly look the same, but the clerk insists there are major differences between them.  How do you even begin comparing seemingly identical items?  Do you take the easy way out and just find the cheapest one or is further investigation warranted?  While it’s unlikely that you’ll run into this exact scenario, it’s not uncommon to be overwhelmed with the window to choose for your home since many look identical, but can have major differences in quality and price.  Deciphering the distinguishing characteristics between windows means understanding several technical terms.  Here’s the jargon you’re likely to hear when shopping for windows and what each means.

The U-Factor: The U-factor of tells how much heat a window passes from inside your windowhome to the outside.  U-factor ratings typically fall between 0.15 and 1.20.  The lower the U-factor, the better the window is insulated and the lower your energy bills are.

 

 

 

 

 

Solar Heat Gain Coefficient: This rating focuses on the amount of heat that is broughtwindow2 into your house from the outdoors through the outside.  The rating system ranges from 0 to 1.  Lower numbers are better because they show that your home will stay cooler in the summer months because the window is effective in blocking heat from the sun’s rays.

 

 

Visible Transmittance (VT): This rating is intended to disclose how much light shines through a window.  It is measured on a scale from 0 to 1.  The higher the VT number, thewindow3 more sunlight will shine through a window.  Factors that influence a window’s VT include the number of panes, glazing type and any glass coatings.

 

 

 

 

 

 

Air Leakage: This discloses the amount of outdoor air that infiltrates a home through the product.  The most common range is 0.1 and 0.3.  A lower number indicates that the winproduct does a better job at blocking outside air.  This number is not something that manufacturers must disclose.

 

 

 

 

Condensation Resistance: As the name suggests, the purpose of this rating is to reveal the window’s ability to stop condensation from forming.  In this case, a higher number is nbetter and the range can be anything from 1 to 100.  Manufacturers are not required to disclose this number.
