Energy-Efficient Double-Slider Windows in Toronto & GTA

Good ventilation doesn’t have to mean giving up energy efficiency. When locked, NorthShield double-slider windows create an airtight seal, while their multi-chamber vinyl construction is designed to support insulation and strength.

You can also add triple-pane glass and Low-E coatings, while NorthShield’s Super Spacer technology helps reduce condensation and improve overall energy efficiency.
