CLERA WINDOWS + DOORS · VINYL WINDOWS GUIDE
A double-hung window is a window with two sashes — an upper and a lower — that both slide vertically within the frame. This allows you to open either the top, the bottom, or both at the same time for flexible ventilation control.
Double-hung windows are a classic style that suits a wide range of home designs, from traditional to contemporary. They are commonly used in bedrooms and living areas where exterior access and cleaning ease are priorities.
Compared to casement windows, double-hung windows offer slightly less airtightness because the sash slides rather than compresses against the frame. However, modern weatherstripping and multi-point locks have significantly improved their energy performance. The right choice depends on your priorities — casements for maximum energy performance, double-hung for versatility and classic aesthetics.
Why Clera? Clera double-hung windows feature tilt-in sashes with easy-glide hardware and are available in a range of frame colours and glass packages.
