ComfortWorld Windows                    
                                    Save Energy and the Environment

Did you know that inefficient windows can lose up to 40% of a home’s heating in the summer and up to 50% of cooling in the winter? These are facts you just can’t afford to ignore.

Because over 75% of your window is glass, the glass is the most important component for energy conservation.  The overall efficiency of the glass is dependent on the sum of the parts:  the glass, the space between the glass and the spacer system. With Window World we build every window using the best, most reliable and energy efficient glass materials available. 

Glass with Low-E & Argon Gas (Optional, yet highly recommended)

Maximize the energy efficiency of your windows with the addition of Low-E and Argon Gas. This option is the perfect long-term solution for reducing those ever-increasing utility bills and for increasing your home’s year-round comfort level. Our super energy efficient glass is designed to keep your rooms warmer in the winter and cooler in the summer while protecting your carpet, furniture and window coverings from harmful UV rays.

Intercept™ Warm Edge Spacer System

Window World windows come standard with PPG’s patented Intercept™ Warm Edge Spacer System. This spacer features a unique, one-piece, U-channel design that creates an effective thermal barrier to help reduce conducted heat loss through the window and to create a stronger, more gas retentive barrier over conventional spacer designs.

It all adds up.

1. Low-E glass improves the energy performance of your window by 24%, over standard insulated glass
   
2. Argon Gas, which is a better insulator than normal air, adds another 6%
   
3. Intercept™ Warm Edge Spacer System, adds another 5%.
