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

Energy Efficiency

Connecticut is known for having very hard winters and hot summers. If you make the excellent decision to have your replacement windows installed by Advanced Window Systems, LLC, you will save lots of money on your energy bill. Over our 40 years of installing windows in Connecticut, we have conducted the research and found the places that lose energy are the frame, glass, and edges. These areas are where the drafts will come through. We have added multiple panes of glass with Low-e coating and argon gas. We fill the frame with foam and also add weatherstripping to the edges. These additional steps set our windows apart to ensure that your windows are totally sealed. 

Advanced Window Systems, LLC offers the best energy-efficient windows for your Connecticut home. The seal on our replacement vinyl windows has a .02 air leak rating. This rating puts us above the competitors! We add extra panes of glass, multiple seals, and strong vinyl to every window to maximize energy efficiency so that you are worry-free!
