Alpine 80 series vinyl windows
Our initial whole house installation of Alpine 80 series retrofit windows was in 2009. We were happy how they kept our home warmer in the winter and cooler in the summer. Three years later, we noticed spots within the dual panes. Since then, of the 17 windows, (33 panes of glass) that were installed, 12 have been needed to be replaced and I will be making our 4th claim shortly to have an additional 5 panes replaced. We were told the batch of windows we received were a bad design and no problem getting them replaced. Glad to hear that however, I should not need to replace windows every few years. Not pleased.
