CURVED DOORS - END OF PRODUCTION
Please note that due to a refocusing of business priorities and expansion of our balustrade business we no longer manufacture curved sliding doors (the Curvaglide® range).
We continue to offer support to previous buyers of our doors, and all documentation and installation guides are available in the pages linked here.
For our existing Curved Door clients, should you need to contact us, please call 01342 410411, or email enquiries@balconette.co.uk quoting your order details, and we will be back in touch.

What Does U Value Mean?

U Value Explained

A U value is a measure of heat loss in a building element such as a window, door, wall, floor or roof. It measures how well parts of a building transfer heat. The lower the U value the better the thermal performance of that element, meaning it loses less heat. The units are measured in thermal conductivity and designated in Watts per square metre required to change one degree centigrade (or Kelvin). In simple terms try to imagine it as how much heat you lose to the outside of your door/window. The higher the number the more energy you are losing.
