my home is a brick cape cod ,three blocks from the coast. when my wife and i were considering new windows the good house keeping recomendation had a lot to do with our choice for replacements.also my sister in law had just purchased them for her house after much research.i had them installed two years ago and feel that it was the best money ive spent on my house yet. they are very quiet[im in a flight zone and close to an interstate highway], and we are often hammered by north winds from the chesapeake bay.the installers were quick ,courteous, and professional.the only thing i would recommend to them ,is that they should use wooden blocks on the interior casings to avoid hammer dents on wood work. we do feel good about the purchace, and even better about the cheaper utility bills. thanks progressive windows you did a great job,and thanks richard for explaining everything in detail.
