Why Homeowners Love Our New Windows

Fiberglass windows are our specialty because they are the best choice for style, energy-efficiency, and value — at a great price. Compared to the standard vinyl, fiberglass replacement windows will last longer and remain trouble-free for years to come.

Fiberglass has an amazing strength-to-weight ratio, which is why it’s the material of choice for boats, bridges, guard rails, and ladders. It’s highly durable, doesn’t leak or corrode, resists rot, and resists expanding and contracting in temperature swings. You would never ride in a boat made of vinyl or climb a ladder made of vinyl, so why is it a good idea to build new windows out of vinyl? These are the main reasons we prefer fiberglass windows over vinyl:

  • Fiberglass windows are slimmer than bulky vinyl alternatives which means a LARGER VISIBLE GLASS AREA!
  • Vinyl windows often fog up after only a few years
  • Fiberglass offers a wider variety of style choices
  • Vinyl windows often lose their air-tight seal and leak cold air into your home
  • Vinyl windows are often made cheaply and can easily become stuck or difficult to operate

We recommend fiberglass windows to almost everyone who asks us about new window replacement – and we’d love to tell you more about the cutting-edge advantages of fiberglass.
