Proven window quality

When researching which replacement window is best for you, many factors lead up to making that final decision.  Lucky for you we have tested Infinity windows in Colorado.  We know from installing Infinity windows for 17 years that they are simply the best window for your home.

Longer life expectancy

Infinity’s fiberglass windows have a 38% longer useful life expectancy than vinyl.

Low E insulating glass coatings

Extremely thin coatings of special low emissivity (Low E) metallic material are applied to glass panes to boost their energy efficiency and block out UV rays. Since glass choice plays a big factor in window and door efficiency, your local Infinity partner can provide recommendations on the best selection for your home.

Resale value

When selling your home, new windows and doors provide an average 73% return on investment — which ranks higher than most interior renovations.

Lifetime warranty

Even though Infinity products are Built for life®, we proudly offer a Limited Lifetime Warranty to give you peace of mind. It’s our pledge to you that we will stand behind our products for as long as you own your home. Because some decisions, like replacing your windows, should only be made once.

An investment that pays
