Imperial Windows feature fusion welded joints on all frame and sashes corners. Imperial series use 3/4″ inch insulating glass units. Dual pane insulating glass units greatly increase energy efficiency. Strong vinyl construction transfers as little as 5% of outside energy, keeping you cool in the summer and warm in the winter. Auto locking window locks come standard on all Imperial Vinyl Windows. They lock securely in one motion.
