Our Vertical Sliders are the perfect solution to any period property that should, and rightly so, maintain its traditional look. In keeping with the properties original features and character we also provide versatility of a sliding sash window thats low maintenance, rattle-free modern construction and highly energy efficient. The construction of our uPVC sliding sash windows compared to the more traditional timber box sash window differs most in the means of holding the sliding sashes in position. Instead of weights, pulleys and a cord, we build in a sophisticated set of spring and spiral balancers that maintain the sash retention. The design of these retainers enables the window to carry sash weights far greater than wooden frames offer. Its our pleasure to bring a beautiful period property back to its former glory that can be enjoyed for many years to come.
