Solarseal products are made in Atlantic Canada by Extreme Windows and Entrance Systems to withstand the extremes of our coastal climate. Homeowners and contractors alike chose Solarseal for the difference in quality the name brings. Differences like our larger insulating air spaces (11/16” or 7/8”) in our double-glazed sealed units. Like metal installation brackets that ensure structural integrity with the building frame. Like a variety of brickmold, casing and drywall return options in our Heritage Series. Or our economical, all-in-one Premium Integrated Series with built in brickmolds and drywall returns. Discover the Solarseal difference.
