Proformance Manufacturing, Inc. manufactures Premium Windows and Patio Doors in Lone Rock, Wisconsin. We proudly introduce the new EcoStar fiberglass window line.
The new EcoStar fiberglass window line by Proformance Manufacturing is without a doubt "Built with Future Generations in Mind." One hundred percent of the materials that go into our new EcoStar windows come from within a 500 mile radius of our Lone Rock manufacturing plant. Adding to the ecological benefit, fiberglass is a renewable material.
Durability, coupled with a close resemblance to wood, makes fiberglass an attractive higher-end alternative to vinyl and a comparable alternative to wood. Furthermore, fiberglass windows can be used in all climates, from frigid to hot and humid. Fiberglass windows will maintain their rigidity even during extreme temperature changes.
Fiberglass windows are maintenance free; resisting rotting, warping, and cracking, and are more energy efficient than aluminum and stronger than vinyl.
EcoStar windows are available in:
Double Hung
Horizontal Slider
Casement
