PVC Casement Windows

Versatile, attractive uPVC casement windows

Casement windows are the most popular type of window for the British homeowner – their popularity being in a large part due their flexible configuration options. Alpine Glass are able to install windows in virtually any configuration to suit all installation spaces, with fixed side or top lights to accommodate multiple style and performance requirements. With slim sight lines and a choice of either sculptured or chamfered profiles (with various colour configurations) they are also made to look good in any home.

Designed with efficiency and security in mind

Like our other uPVC windows, casements from Alpine Glass are also extremely energy efficient, being constructed from an efficient multi chambered design which significantly reduces heat loss, external noise, and greatly improves thermal retention. Our casement windows are able to achieve a WER (Window Energy Rating) of ‘A’, which more than exceeds current building regulations which require new housing to be fitted with ‘C’ rated windows.

To help keep your home secure, Alpine’s casement windows can be fitted with highly secure locking systems. Their multi chambered construction also allows for them to be fitted with additional steel reinforcement should it be required, giving you ultimate peace of mind when it comes to your home’s security.

For the more traditional style of home, Alpine Glass are also able to manufacture and supply a stunning range of timber casement windows.
