I'm new to this forum, but I can tell you it has been incredibly informative. Has anyone heard of a Massachusetts company called National Vinyl Products in terms of the quality of their replacement windows? They make a brand that goes by the name Trustgard and/or Northwind III. Thanks!
I have used their windows a couple times upon request, but was never really a fan. I have a sample of one of their windows that I use to demonstrate why the lines i carry are better constructed.
