Casement Windows for homes across Dorset

There’s something quite ironic about casement windows. On the one hand, their clean appearance is understated and simplistic. On the other, they are one of the most versatile styles of window on the market. For this reason, no matter what age, size or style your current property is, we guarantee there’s a casement window available that will enhance its current look without being unsympathetic to the original characteristics. However, if you are more concerned with improving home performance instead of appearance, casements are more than capable of helping you out here too. Efficient, low maintenance and loaded with great security features, whatever your reasons for wanting new windows, casements from Poole Joinery are up to the task. We also offer other window styles such as flush sash windows and tilt & turn windows.

Extremely Efficient Casement Windows

Enjoy a warmer home for less with naturally insulating uPVC & thermally broken aluminium casements

uPVC: The profiles we use for our uPVC casement windows are exclusively sourced from uPVC specialists Deceuninck. These high-performance profiles make full use of uPVC's naturally insulating qualities, trapping copious amounts of heat inside your home. By keeping the heat in, your home environment will be noticeably cosier.

Aluminium: Our aluminium windows employ a different kind of thermal technology, although they achieve a similar result. Their frames are fitted with polyamide thermal breaks. These significantly reduce heat transfer by negating the conductive qualities of aluminium. As you can rely on your windows to retain more heat, you can spend less fuelling your central heating system to warm up your home too.

Casement Windows with Robust Security

Keep you, your family and your belongings safe

Both our uPVC & aluminium casement windows are secured around the frame by multi-point locks. They can also utilise internal glazing and side-security brackets for additional security. Regardless of which casement window material you require, Secured by Design (SBD) accreditation is attainable, so your home will be properly reinforced against intrusion. It's important to feel safe and sound in your home and with our casement windows, you can feel exactly that. Your home will always be secure, allowing you to relax in complete peace of mind throughout the whole day.

Highly Customisable Casement Windows

Achieve the perfect appearance for your home

In terms of design, you can decide whether you’d like sculptured or chamfered frames. Sculptured frames feature soft sculptured lines, creating a look that is often found on country cottages and other traditionally styled properties. To further complement a traditional aesthetic, Georgian bars are also available. The lines on chamfered frames are much sharper and more clearly defined, for an appearance that lends itself to more modern looking homes. There’s also a selection of window furniture to choose from so you can personalise them your way. Additionally, Poole Joinery can tailor the size of our casement windows to fit smaller and larger apertures and those in between.

Durable and Easy to Clean Casement Windows

Long-lasting windows with the minimal amount of hassle

Due to their exposure to the weather, it’s essential for windows to be durably built. Fortunately, our uPVC & aluminium casements are exactly that. UV rays can cause cheaper uPVC frames to discolour over time but ours will hold their colour. Also, our aluminium casements resist corrosion & rust, and they are immensely strong. Both have been tested to withstand heavy storms and freezing temperatures so extreme weather conditions are not a problem. Both materials are equally easy to clean too, so there is no need to worry about excessive upkeep either!
