ULTREX FIBERGLASS WINDOW PERFORMANCE

Cold, heat, and time – no worries

Ultrex resists the ravages of cold, heat, time and pressure to provide the most worry-free windows and doors available today. While vinyl can distort in extreme heat or streak and crack in the fluctuating temperatures, Infinity products offer the highest level of performance and are virtually maintenance-free.

In Denver, Low thermal expansion means a stronger seal

Ultrex has an extremely low thermal expansion rate, which keeps the window stable and weathertight, reducing the risk of seal failures and air leakage into your home.

Tired of windows that are difficult to operate?

The low expansion of Ultrex means Infinity Windows resist sticking, swelling, and warping, providing easy operation for the life of the window.

Tired of high-maintenance windows?

The low expansion of Ultrex means Infinity’s patented finish stays looking like new and is virtually maintenance free. It resists discoloring, warping, rotting, corrosion, denting, rust and doesn’t require sanding, scraping, or painting.

 

 

For window replacement, the difference is in the details

Vinyl windows can arrive with messy welded corners, and bulky profiles that reduce your view. Infinity windows arrive with clean mechanically-bonded corners, traditional details, and narrow profiles to maximize your view.

 

Replacement Window durability – Built for a lifetime for the Denver climate

Marvin Ultrex Replacement Windows are as strong as low carbon steel and 8x stronger than vinyl. It’s so tough we have to use diamond-edge blades just to cut it to size. The strength of Ultrex translates into superior stability, long-term ease of operation, low-maintenance, and superior performance.

At Gravina’s Window Center of Littleton we strive to make every project we undertake easy and enjoyable for our customer. We pride ourselves on the honesty and integrity of every member of our family, from our crews all the way up to our owners.
