What are double glazed casement windows?

Double glazing is an energy-efficient way to insulate your home. It is made up of two layers of glass with a small gap between them which are sealed together, forming a barrier that helps reduce heat loss and noise pollution. Double glazed windows come in various styles and can be used to enhance the aesthetics of your property. In this article, we will explore the different types of double glazing, so you can make an informed choice when considering new windows.

Casement windows are the most common type of double glazing and are typically hinged at the side. The frames can be made from either UPVC, wood or aluminium and the windows usually open outward. They are available in a variety of finishes and styles, such as flush casement, inward-opening and outward-opening. Double glazed casement windows provide excellent energy efficiency, as well as extra security because they can be locked shut. 

What are tilt and turn windows?

Tilt and turn windows are double glazed windows which have two separate mechanisms for operation. They can be opened inwards or outwards and the handle can be turned for ventilation, or tilted for egress. These versatile windows are great for both ventilation and safety, as they can be easily opened to allow fresh air in, and also securely closed if necessary. Due to their unconventional design, tilt and turn windows provide an interesting architectural feature to your home, so they are perfect for those looking to add a unique touch.

Double glazed vertical sliding windows are a great option if you want to update your windows while keeping the traditional sash window design. 

What are double glazed sash windows?

The traditional look of these windows makes them a popular choice for those looking to add period charm to their homes.
