Noise Reducing
Our Secondary double glazing installations are capable of reducing noise by up to 80% (over 50dB). That’s enough to quieten the busiest railway line or rumbling road – helping you to create a peaceful and stress free environment in your home.
Thermally Efficient
By adding an insulating layer of air and a second barrier to the elements, you can greatly reduce thermal energy waste. In fact, our environmentally friendly secondary double glazing can help you reduce draughts and cut heat loss by up to 65%.
Beautifully Crafted
Our secondary glazing is so popular because it’s highly functional and looks stunning. It merges seamlessly with most window styles, features slim and discreet aluminium profiles for minimal sight lines, easy access to primary glazing and secure night ventilation.
Safe & Secure
Secondary double glazing offers a number of security advantages over single windows. They are extremely difficult to open from the outside and provide an additional barrier. In addition, our frames are made from a tough aluminium and securely fixed in order to resist forced entry.
