uPVC Bow and Bay Windows

We install uPVC bow and bay windows across Blandford, Poole, Bournemouth, Canford Cliffs, Sandbanks, Westbourne, Wimborne, Shaftesbury, Gillingham, Sherborne, Dorchester, Yeovil, and surrounding areas.

Our uPVC bow and bay windows are perfect for homeowners who want to make a feature out of their windows. The curved shape of bow windows and the contemporary, angular style of bay windows are both excellent for letting in natural light. Their multi-faceted design means they make the most of the available sunlight, even as it changes position.

Bay windows are better suited to modern homes and are particularly ideal for creating window seats or storage space. Bow windows are excellent for complementing more traditional or period properties. This means that whether you have a country cottage or new-build townhouse, our uPVC bow and bay windows can work for you.
