What is a casement window?

Casement windows are hinged on one side so they open fully outwards. Our range of Casement Windows have multi-locking points, premium security features and come in a wide choice of colours and finishes. They suit most property styles and are a popular choice for replacement windows.

This window type has an opening sash which is within the insulated frame, so they are exceptionally thermally efficient without the need for expensive glazing. Casement windows are often installed in conservation areas, or in heritage or period properties, due to the wide range of colours and options on offer, without any compromise on style.

Here are just some benefits of installing a casement window from Trade Frames UK:

Casement windows
    • Thermally efficient: Up to an A+ energy rating system, keeping the cool air out and the warm air in and helping you to save money on your heating bills. Our windows can achieve a 1.3 u value, which measures the rate at which heat is lost through a window – the lower the u value the more energy-efficient the window.


    • Triple or double glazed: Modern double glazing is incredibly thermally efficient, but for even greater performance, triple glazing is available.


    • Acoustically efficient: High specification frames and glazing helps to keep outside noise outside.


    • Superior security features: Up to 8 multi-locking points, centre locking, stainless steel construction and hinge guards protect against unwelcome intruders.
