Which are Better: Casement or Double-Hung Windows?

There are two main types of sash windows, casement windows and double-hung windows, each have their own advantages and disadvantages. If you are looking to decide between the two, you will need to weigh up the pros and cons before deciding which is best for your space.

What is a Casement Window?

A casement window is a type of sash window that has hinges on the side, where it attaches to the frame. They may open inward or outward, but usually it is outward.

Pros of Casement Windows
Different glazing options
Good ventilation
Many different design options
Can fit to many types of frame

Cons of casement windows
Not suitable for use with air conditioning units
Casement windows are not suitable for storm windows
No potential for adding screens
Some casement window frames will not be strong enough for larger size windows

What is a Double Hung Sash Window?

A double hung sash window is a design with 2 separate sashes, those being the top and bottom window. Both of these slide up and down. If it is a single hung sash window then the top window will be in a fixed position, and only the bottom window will move.

Pros of Double Hung Windows
Easily ventilation and ability to control air flow
Suit traditional and contemporary buildings
Simple to clean inside and outside of the glass
Suitable for air conditioning units and other additions
Wide variety of colours and designs

Cons of Double Hung Windows
