Heat Loss and Gain for Windows

We offer high-quality, energy-efficient window installation for our customers. All our products are well-equipped to cut down on heat transfer in and out of your home. This isn’t just a bold statement; it’s a scientific fact. Here’s how our windows can help your home remain comfortable no matter what the temperature is outside.

How it Works

Sunlight is the biggest cause of heat transfer, and it’s exactly what your window is trying to counter. During the summer, infrared and UV rays are conducted through the glass, frame and other parts of your home. During the winter, heat from inside your home escapes outside through your windows.

There are two measurements of heat transfer: U-factor and the solar heat gain coefficient (SHGC). U-factor measures the rate of non-solar heat conduction to determine how much heat is absorbed, while the SHGC determines how much solar radiation that pushes through. Keep this in mind when shopping for your next double-hung, casement, sliding or bay window.

How We Help

Finding the right window requires checking these ratings. With lower scores, the product can cut down your energy bill by a significant amount. That’s what makes our products top of the line. They have been approved by ENERGY STAR® and have low ratings in both U-factor and SHGC.

This is largely thanks to our Fibrex® frames and specialized glass packages. Fibrex is made of recycled wood fiber and composite material, making it highly insulative. Our High-Performance™ Low-E4® windows are over 50% more effective than regular windows at reducing heat transfer. Together, they make all our products energy-efficient. That’s why our sliding and custom windows have stood the test of time in many homes over two decades.
