What Are Single-Hung Windows?

Single-hung windows are window constructions with a fixed top sash and a movable bottom sash that slides from the bottom. To open the window, the two sashes overlap, therefore maximizing the space around the window. This window style is normally installed in bedrooms and areas that receive high traffic, such as patio areas. Since the top sash remains stationary, a single hung window is suitable for spaces where the upper sash is located high up and mostly out of reach.

Providing timeless style and practicability, single-hung windows in Ottawa offer excellent ventilation and allow more natural light to enter your house. And because the top sash remains closed, these windows are energy efficient. Their operation is also effortless as all you need to do is slide the bottom sash to open and close the window.

The single-hung windows we provide to customers across Ottawa are adequately sealed and are waterproof. They are also secured with a multi-locking system to ensure the excellent security of your home. These windows are designed to serve you for a long time without fading, rusting, or cracking.

Frequently Asked Questions

Why should I choose a single window?


Since only the bottom sash moves and the other remains fixed, single-hung windows are ideal for homeowners looking for an affordable window in both replacement and repair.

Can I clean single-hung windows from the outside?


Yes. Since the bottom sash tilts in, you can clean both the exterior and interior surfaces inside your house. However, you would have to clean the outer surface of the top sash from the outside since it does not move.

How do single hung windows function?


In single windows, the bottom sash slides up to close and open the window while the upper sash remains fixed.

What is the difference between a double-hung window and a single-hung window?


The difference between these two window styles melts down to the number of sashes that move. While in single hung windows only the bottom sash moves, in double-hung windows both upper and lower sashes are operable.

Is a single-hung window more energy-efficient than a double-hung window?


Yes. This is because the window has a completely sealed and stationary sash, unlike in a double-hung window where all sashes move. The small spaces left between the sashes and frame when the window is closed could allow heat to escape in double-hung windows.
