Double-Hung Windows in Simcoe County & the GTA

Double-hung windows are popular because both sashes can move vertically inside the frame. That makes it easy to control airflow without requiring exterior clearance for an outward-opening sash.

The key difference with a double-hung window is that both sashes are operable. The lower sash can be raised and the upper sash can be lowered, giving you more control than a single-hung design.

Because the sashes stay within the frame while moving, double-hung windows are useful in locations where an outward-opening casement or awning window could interfere with a walkway, patio, deck or landscaping.

Energy performance is not determined by the words “double-hung” alone. The selected glass package, frame construction, weatherstripping and installation quality all affect how the finished window performs.

For Ontario homes, it is worth confirming the exact glazing and performance data for the configuration being quoted rather than relying on generic claims that may not apply to every window.

Both styles use vertically sliding sashes, but the number of operable sashes changes how you ventilate and clean the window.

Their vertical operation makes double-hung windows especially practical in areas where exterior clearance is limited.

A good double-hung replacement starts with the opening, the room and how you plan to use the window. MK Windows & Doors helps homeowners compare compatible configurations before the unit is ordered.

Accurate measurements and proper installation help both sashes operate correctly and help the window seal as intended.
