01205 311144We offer a wide variety of window styles to suit any architectural style and taste. This includes classic casement windows, flush sash, sliding sash, tilt & turn and French windows. Contact us to find the perfect fit for your project.
The material the window frames come in will depend on the style you choose. All of our window styles are available in uPVC, and our casement, flush sash and tilt & turn windows can also be made with aluminium.
No matter what style you choose, all our windows are designed with energy efficiency in mind. Features like double glazing and thermal break technology help to minimise heat loss, keeping homes comfortable and reduce heating and cooling costs.
Absolutely! Security is a top priority. Our windows incorporate multi-point locking systems and robust hardware to protect against potential intruders.
Of course – we offer a range of customisation options including colours, finishes and hardware. You can even choose decorative glass!
Choosing between uPVC and aluminium windows depends on your priorities. Aluminium windows boast a sleek, modern aesthetic with slim sightlines that maximise natural light, making them a popular choice for contemporary homes. However, uPVC is a more budget-friendly option which still delivers excellent thermal efficiency, keeping your energy bills low. Both materials are exceptionally durable and weather-resistant, ensuring long-lasting performance for your house windows!
Contact UsSecurity is paramount at Boston Trade Frames, and that applies to all our windows, regardless of material. Both our uPVC windows and aluminium windows incorporate multi-point locking systems, engaging multiple locking points within the frame for superior strength. We use industry-leading hardware known for its strength including Fab & Fix, APCES and Winkhaus.
