Integrity® windows and doors are manufactured with Ultrex® pultruded fiberglass, which is a material that has revolutionized the fiberglass products category. Ultrex® is durable, stable, low maintenance, energy efficient, and cost effective. It will outperform roll-form aluminum, vinyl, and all types of composites in virtually every performance category. It is eight times stronger than vinyl and three times stronger than wood/vinyl composites. This means that as a house settles, Integrity® windows will resist sagging and stay true to its shape. Integrity products are built to last.
Whether building a new house or remodeling your existing home, Integrity® windows offer many options for new construction and replacement applications. Integrity® windows are now offering special sizes and exterior installation accessories, which will make the installation process much easier and cost-effective. The 10 business day delivery period will ensure you will have the windows you ordered, when you are ready for them.
