We chose Nordik windows for the large panes and small frames profile - we wanted to maximize the window panes. The insulation properties also sold us. The windows were ordered and installed in a timely fashion, according to plan. The Installation Team: VINCE, JEN, and CHRIS were friendly, (with us and our dog), courteous, and took great care to get the job done properly and professionally. They also did a great job cleaning up the mess, even working outdoors in the rain to tidy up. The windows are beautiful, open and close easily and provide noticeable insulation against outdoor noise.
