uPVC Bay Windows in Bromley and Dartford, to Maidstone and Sevenoaks

Bay windows are commonly found on heritage properties, but their elegance and character can effortlessly suit any home. With 150+ RAL colours and a range of authentic wood effects, as well as being able to incorporate either casement, sliding sash or heritage window styles, our uPVC bay windows will be bespoke to your home. Bay windows tend to use three windowpanes, however, for larger spaces we can install more panes to perfectly fit your home. They curve outwards from the exterior wall to create a large window sill or seating area, giving the illusion of an extended living area. With slender uPVC frames, they provide wider views of the outside whilst letting in an abundance of natural light, creating a bright and airy feel to your home’s interior.

Our high-performance uPVC bay windows are fabricated using modern uPVC and state-of-the-art manufacturing techniques. With multi-chambered frames and either advanced double glazing or comfort glass, your property will benefit from A energy ratings and low U-values. The uPVC frames are coated in a protective coating which makes them weather-resistant, low maintenance and resilient against fading and corrosion. All our classic uPVC bay windows are fitted with multi-point locking systems as standard and they are rigorously tested to ensure that they will protect your property against even the most sustained attempts at forced entry.
