The cutting-edge fiberglass framing systems of Alpen High Performance Products from Energy360 Solutions offer superior performance to conventional fenestration materials in a number of ways: durability, stability and efficiency, making it the optimum material for super-insulating windows and preserving overall performance for the life of a window.

  • Extreme corrosion resistance: fiberglass is the only framing material that particularly resists environmental damage caused by corrosive salt air or high temperatures.
  • Superior insulator even in extreme environments: dimensional stability even in extreme thermal cycling (heat, cold humidity), Alpen fiberglass frames offer the aesthetic of classic wood clad windows but with better insulation.
  • High condensation resistance: the insulating nature of fiberglass prevents condensation and helps keep humidity within a proper range, this limits the growth of molds and mildew and helps keep your home’s interior air quality healthy.
  • Superior strength to weight ratios: making Alpen fiberglass series ideal for large window openings.
  • Practically maintenance free: the inherent strength and nature to distribute impact loads even in sub-zero temperatures, fiberglass frame will not suffer the pockmarked, surface damage that is prone to wood and aluminum windows, and because fiberglass takes paint easily with excellent adhesion, you are not stuck with the color of your windows for a lifetime.
  • Very low coefficient of thermal expansion and contraction: stresses on seals, caulks and joints are minimized, contributing to higher efficiency windows and tight seals that are resistance to air leakage and water penetration.
  • High glass to frame ratio: the strength of our fiberglass frames means more of a viewing area because of the higher glass to frame ratio, compared to wood windows.

    I own a Victorian style home that desperately needed insulation. I hired Energy360 Solutions and they discovered major air leakage through the many nooks and crannies of my attic.

  • Scott Gillis, Woodridge, IL

    My home was uncomfortable. It was so difficult to keep it warm in the winter and there was no sound barrier. We could hear everything that was going on outside. We needed insulation and called Energy360 Solutions. They provided us with a great solution using dense packed Cellulose insulation.

  • The Holzl Family, Mt Prospect, IL

    After 14 years of living in our house, and suffering each winter in our chilly family room built over a crawlspace, we hired Energy360 Solutions to perform an energy audit of our entire house. One of their findings was that we were losing heat out of the wall joists of the crawlspace.

  • Ken & Julie Kittredge, Mt Prospect, IL

    Our first ever energy audit from Energy360 solutions was a very exciting and interactive experience. We learned so much about the energy efficiencies of our home or better said the lack of efficiencies.

  • Mark Hoffmeister, Mt Prospect, IL

    Our home was sealed and insulated in March 2014. The results were immediate. The house air conditioning was improved especially in the upper floors. This cold winter comfort improvement in heating the house was successful.
