Aluminium Windows



At Bill Butters Windows, we offer a wide range of elegant aluminium windows in Sherborne, Dorchester, Yeovil, Gillingham, Shaftesbury, Crewkerne and surrounding Dorset areas. Our aluminium windows are built using innovative technology to boost thermal efficiency and create slim sightlines. Choose from our versatile range of windows to upgrade the functionality and aesthetics of your property.

We supply and install Alitherm windows that are available in various styles for you to choose from, including casement, sliding sash, parallel casement, tilt and turn, reversible and pivot windows. Our casement windows inherit the timber aesthetics and provide the durability and functionality of aluminium windows. Whether you own a period or a contemporary property, our windows can complement every style and appeal.

We use premium grade aluminium for our windows and doors. Aluminium is an inherently robust and durable material that does not absorb moisture, so your new windows will be free from moulds, leaks, cracks and rot all year round. With just a simple wipe down, your windows will look fresh as the day they were installed.

With various customisations, your slim and sleek aluminium windows will thoroughly ventilate your property. Our commercial project managers can benefit from our comprehensive range of aluminium windows designed to provide consistent airflow throughout multi storey commercial buildings.

We offer Alitherm profiles that utilise innovative polyamide thermal break technology to strengthen the barrier between the chilly air outside and warm air inside. With these thermally efficient double glazed windows, you can reduce your energy consumption and save money on electricity bills.

We offer market leading aluminium profiles such as Alitherm Heritage 300, 600, 700, and 800 series. With multiple customisation options like colours, textures, finishes and accessories, you can enjoy complete creative freedom over the design and performance of your aluminium windows.
