Educational buildings have to stand up to a lot of abuse, and so do their windows. Infinity® products have won many educational replacement projects for the extreme durability of Ultrex® fiberglass. Not only does Ultrex delivers long-term operation and durability; but its strength allows Infinity windows to have narrower profiles and more glass area than most competitive products giving classrooms more natural light.
Infinity products consistently win multifamily projects for their combination of low-maintenance, durability, appearance, and ease of use. Owners and management companies like the durability and low-maintenance of Infinity’s Ultrex fiberglass construction and the support of a large, trusted manufacturer. Occupants and owners like Infinity products for their traditional appearance, easy cleaning features, and effortless operation.
Window replacement in a historical structure can provide a host of unique challenges. Infinity products provide an excellent compromise between historical accuracy and modern convenience. With their narrow profiles and traditional wood-window detailing, Infinity products easily replicate the look of most original wood windows. However, they also provide the owner with a durable, energy-efficient product that offers years of low-maintenance performance.
These facilities often replace windows for reasons unique to the type of use they receive. Infinity has won large projects because of our product’s simple and effortless operation. Low operating force and easy lock engagement make Infinity products easy to operate for individuals in these facilities. Most importantly, residents enjoy year round comfort thanks to ENERGY STAR qualified Infinity Windows.
