Tough Colorado Climate?
Scorching summer heat or freezing winter temperatures – wherever you live, whatever the climate, Infinity from Marvin replacement windows are outstanding performers.
Our Infinity windows and doors are made of fiberglass and are suited for Colorado's weather. We hear all the time about homeowners who have vinyl windows in their home and they are leaking and sagging in under 10 years. So vinyl windows may be cheaper to start, but in the long run, you most likely will have to service and replace them again. This costs you more so you might as well invest in a better window from the start.
Infinity windows can cut heating and cooling costs by 11 to 37 percent.* This is why we don't sell 50 lines of windows. We trust fiberglass in Colorado, plain and simple. We have the track record to prove it too. As one of the oldest fiberglass window dealers in the country, we have had the opportunity to see how durable fiberglass is in our climate. Unlike vinyl or wood, with Infinity you only have to replace your windows once, saving you more money in the long run.
