Napco Windows Reviews 2026
Explore Napco windows reviews from consumers and industry insiders. At one time, Napco manufactured both residential windows and siding that was sold to builders, supply stores and consumers under their own brand name. The company was eventually purchased by Ply Gem. Ply Gem still sells the siding products under the name Napco Siding By Ply Gem (found on the Ply Gem website), but their window division has been essentially stripped of any branding. Ply Gem itself sells a number of different window lines, the names of the Series depends on the part of the country in which you live.

Napco Windows vs. 7D
I am having windows replaced thru a local grant program. They are to replace my vinyl replacement double hung windows with LowE, Napco or approved equal, with tilt in draft free seal, heavy duty locks, two panels of glass.
They have chosen 7D windows which the top and bottom grids are not in line with each other. Where can I get more information to compare what they are installing and the NAPCO documented in quote? I greatly appreciate your help!

Debby, Napco windows are now owned by Ply Gem, a strong company in the window industry. Napco has always been more of a wholesale / retail window and siding company. Ply Gem is a strong company in the window industry.
7D is a wholesale window manufacturer that I have heard very little about. Here is a thread that discusses a bit about 7D windows.

If this were my place, I'd go with the company with the highest profile and that would be Ply Gem / Napco.
Honestly, are these your only choices? Napco and 7D are not exactly the strongest companies in the industry in general. I could name 50 brands that I would recommend over your current choices. I don't mean to complicate the issue for you, but it might be worth asking whether other options are available.
