Progressive Fiberglass

THE WAVE OF THE FUTURE IS HERE TODAY...
PROGRESSIVE FIBERGLASS WINDOWS & DOORS

What make windows different from one another if they all use the same glass?
The FRAMES!

Compared to windows built with other frames, Fiberglass Windows:

• Are stronger and stiffer
• Don’t transfer heat or cold
• Don’t twist, warp or bow
• Are not affected by chemicals, salt or acid rain
• Have the least amount of expansion and contraction 
  (Most similar to the glass, so no gaps or leaks for air or noise)
• Are virtually maintenance free
  

Fiberglass is the most energy-efficient, durable window framing material available today.
