I wanted to let you know how pleased we are with the Green Mountain Zero Draft "Indow" storm windows. By removing the ugly and inefficient aluminum storm windows from the outside of our 1820 cape we restored the original look of the home. The "Indows" have greatly improved the warmth of the house this winter and reduced drafts. We are even more excited in how much it has reduced or almost eliminated the traffic noise on the country road which passes close to our home. The house is also cleaner as road dust no longer seeps in! Pierre, Thanks for your great service, professional measuring, and outstanding service. It was a pleasure dealing with you
