uPVC Sliding Sash Windows in Bromley and Dartford, to Maidstone and Sevenoaks

uPVC sliding sash windows perfectly combine modern uPVC technology with traditional aesthetics. When you want your home to be warm and secure without compromising on its heritage character, our high-performance uPVC sash windows are an excellent choice. Designed to replicate the Victorian window style, they feature a range of period detailing including mechanical joints, run through sash horns, traditional furniture, and your choice of astragal bar configurations. Due to their replica appearance, they are commonly approved for use on heritage properties and in conservation areas. You can choose from over 150+ RAL colours and a variety of woodgrain finishes, so whether you’re looking to add a traditional aesthetic to a new home, or retain the character of a listed property, we can design the perfect sliding sash window for you.

Sliding sash windows have a smooth vertical sliding opening action and they also tilt inwards, making both cleaning and ventilation incredibly simple. With multi-chambered frames and our innovative double glazing, your home will benefit from A+ energy ratings, keeping heating bills low. Unlike timber, our modern uPVC is essentially maintenance-free, easily suiting the busy modern lifestyle. For a modern spin on the elegant style, our industry-leading uPVC sliding sash windows will continue to look and perform like new for at least 35 years.
