I would like to install triple glazed fiberglass insulated casement windows. I also need to install four triple glazed fiberglass sliders/patio doors for a lake view and deck access. I would like to go with Accurate Dorwin of Winnipeg, Canada, but only their windows are EPA Energy Star certified, not their sliders. Please provide a list of manufacturers including Canadian, who manufacture EPA Energy Star certified triple glazed fiberglass insulated sliders/patio doors? Thank You!! JOE jpoland4@cox.net
