Ultrex Fiberglass – What could be stronger?

Infinity from Marvin logoULTREX® FIBERGLASS IS 8X STRONGER THAN VINYL!
You’re doing your homework— comparing replacement window features and benefits. When you’re done, you’ll find that Infinity® from Marvin replacement windows are the only choice for the home you love. The advantages are clear—strength, durability, low maintenance, ease of operation, and classic beauty.

Don’t worry. Ultrex can take whatever your family and mother nature dish out because it’s pultruded fiberglass, a material used in products where strength and durability are required. In fact, it’s such a solid, long-lasting material that it’s trusted for use in bridge construction.

Made with strong cables of glass that are saturated with specially compounded resins, Ultrex is durable, non-corrosive, has low thermal conductivity, and is virtually maintenance-free. The superior strength of Ultrex fiberglass allows the window frame profile to be narrower than those with frames made of vinyl or wood, giving you more visible glass area. And no matter how extreme the temperatures get in your region of the country, Ultrex stays square and true.
