What Makes Our Vinyl Replacement Windows the Best Choice For Your Groton, Connecticut Home?

Energy Efficiency

In the past 40 years of installing windows in Groton, CT, we have done research to find the problem areas of your windows which lose the most energy. Drafts and heat are likely to sneak in through the glass, frames, and edges of the windows. Our several panes of glass along with Low-e coating and argon gas prevent these drafts. Our installers fill the frame with foam and weather-strip the edges. With these measures, your windows are totally sealed. Groton, CT has its fair share of sweltering summers and freezing winters. The choice to replace your windows with Advanced Window Systems, LLC will result in a much lower energy bill.
