Serving Michigan With Over 30 Years Experience
Fiber glass windows have the highest R-value (resistance to heat loss) of all framing materials — better than wood, better than vinyl, better than aluminum. Fiber glass windows and doors also gives you superior durability because of the superior dimensional stability and inherent strength of pultruded fiber glass. Comfort Line FIBERFRAME Windows & Doors provide superior window and door options for both residential and commercial applications.
WE INVITE YOU TO VERIFY THE SUPERIORITY OF FIBER GLASS AS A FRAMING MATERIAL,
through third-party sources created to help consumers select the best efficiencies in windows and doors. While you’re visiting these sites, also check out your best glazing choices. Together, fiber glass and the right glazing choice, make an unbeatable combination. You will also learn by visiting these sites and studying their research information that fiber glass frames will not warp, shrink, swell, rot or corrode. Because of their strength, fiber glass frames such as COMFORT LINE’S FIBERFRAME products, can hold larger expanses of glass.

Quotes Taken From Various Sources About Fiberglass Window Frames

 
"Fiberglass has the highest "R" Value of all window frames."
     -US Department of Energy (DOE)
 
"Fiberglass is the most energy efficient material of all the traditional materials that windows are made from."
     -US Department of Energy (DOE
 
"The Lumber of the Future"
     -Popular Science, June 1995
 
"Fiberglass has high tensile strength - four times that of steel - so it won't warp or twist."
     -Popular Science, June 1995
 
"Fiberglass is the ideal material from which to make window frames.  I consider Fiberglass Windows to be the State of the Art Windows."
    -Michael McCabe, PhD, ASHRAE - Research Scientist
 
"Fiberglass windows are highly resistant to ultraviolet radiation, which over time can cause PVC (vinyl) to break down and disintergrate."
     -Michael McCabe, PhD, ASHRAE - Research Scientist
 
"Fiberglass has the strength and durability of metal."
     -InLine Fiberglass Limited
 
"All vinyl becomes brittle in extreme cold, expands and softens in extreme heat; wood -rot prone, high maintenance;" and "fiberglass --good insulator, rot proof, low maintenance, withstands heat, cold, moisture and can be painted."
     -The Reader's Digest Do it Yourself Manual
 
"Another advantage of  fiberglass frame material is that expands with temperature change at almost the same rate as the window glass.  This results in a consistently airtight fit no matter the season or time of day."
