Ply Gem Windows & Doors

Windows orinally installed by Gienow windows and doors 10 years ago. Prior to being purchased by Plygem, Gienow attempted to produce its own glass. The issues I had at 10 years were all with Gienow produced glass. Plygem honoured the Gienow warranty but I had to pay for labour. Six window replacements were done over the period of a year. No condensation to speak of but rather a ghost like plume. Challenge to take a warranty photo that would show in a photo. Strong and knowlegeable service department! Plygem uses Cardinal glass sourced in the U.S. Checkout the Cardinal website. Awesome outfit.
