Infinity all-Ultrex fiberglass windows can immediately cut home energy. Test results show that energy used to heat or cool your Littleton area home can be lost through poorly insulated doors and windows. Littleton, CO and surrounding area homes with unsatisfactory and drafty insulation often suffer from unnecessarily high utility bills. The combination of poorly fitted frames, inefficient glass and porous wood or vinyl frame materials combine to waste the money you spend to keep your home safe and comfortable.

Infinity replacement windows look like traditional wood, but are a more dependable option in comparison to traditional wooden windows. Specially designed Ultrex® fiberglass technology makes these windows energy efficient and tough, so they will open and close like they should every single time. Infinity windows remain weather tight and stable in all climates. The risk of air leakage is reduced thanks to the low thermal expansion rate of fiberglass. Available in a variety of standard types, shapes, and sizes, Infinity windows are also customizable to meet the needs of any space in your home. They incorporate the details of traditional wood windows without the maintenance, so you will be satisfied that you upgraded to Infinity windows from Gravina's Window Center.
