Casement Windows in a Range of Styles and Colours to Suit All Homes

Our uPVC casement window is our best-selling window style for good reason. It’s a complete system available in both bevelled and fully featured, making it a versatile choice for any home. As with all our products, they’re manufactured from 100% lead-free material. We offer a wide range of casement window styles in a variety of colours. With plenty of accessories to choose from as well, they’re sure to suit any property.

Just like the rest of our product line, our casement windows can be fully customised to meet your specific needs and preferences. From different colour options and mock horns to hardware and soundproofing, you’ll find yourself spoilt for choice with Emerald. Although we specialise primarily in uPVC, we also offer wooden casement windows. Made from hardwood, they’re a durable and long-lasting addition to any home. Whatever you’re looking for, we can help!

We know that security is paramount, so our casement windows comply with enhanced security standards and are also BBA and BSI accredited. In addition, all our casement windows have unique 14-point locking systems. They’ll help keep outside noise where it belongs—outside. The ‘A’ energy rating means the casement windows will help you stay cooler in summer and warmer in winter.

Customer Reviews

Very pleased with my new windows and doors. They look great! William and George did a brilliant job fitting them. Very clean and tidy workers . A great experience from start to finish. Will recommend this company to others.

Grace Grattan

Emerald recently completed a two day job for us. The quality of the windows & door fitted are first rate. Their communications were very good prior to the work, & they rang ahead on the day they were due to start to confirm what was due to be carried out.

They made the procedure from start to finish a smooth one. We would fully recommend them for future use.

Ian Longdon

We had our windows and doors replaced with Emerald Home Improvements. Absolutely first rate service, they worked all day without stopping and made a first class job. I am very happy with the company and the work. This is a very efficient, well run company and I highly recommend them. I have since ordered guttering and fascias. Thank you to everyone at Emerald and especially to Steve and Scott.
