What is a Casement Window?

The Casement is the part of the window that opens. Casement windows are a type of window that is attached to the window frame which opens and has hinges attach at the top, bottom or to the side. Casement windows are probably the most popular type of window in the UK and have been in production for a long time. The reason casement windows are one of the most popular types of windows is because they are very reliable, durable and energy efficient.

Fully sealed for insulation

Fixed pane windows obviously offer the best level of insulation and energy efficiency, but casement windows aren’t far behind. All casement windows are fully sealed as the window sash presses against the frame to create an airtight seal when closed. This helps prevent cold air getting in and warm air getting out, improving the energy efficiency of a home and reducing heat loss which should save you money on energy bills.

Simple to use

They are very easy to open and close also due to their configuration they can even be installed alongside automatic openers.

Unobstructed views

Casement windows give an unobstructed view when open and when closed, they also allow a lot of light into any room.

Ventilation options

Unlike their double hung windows counterpart, casement windows are open top to bottom and can be opened all the way out for maximum ventilation. However, they can also be angled slightly to catch breezes, helping to circulate air around the house.
