I purchased Newpro windows for all my downstairs windows June 2009, It made a significant improvement in keeping my house cool during the summer. With the Winter approaching, I already notice how well heat is being kept in downstairs rooms. Cold air leaking through my upstairs windows are now much more noticeable. I now intend to have Newpro replace the windows on the second floor. The Newpro windows are very easy to open and close. Workers on first job were competent and worked efficiently.
