Whilst glass has probably always been most people’s preferred choice for roof glazing, its weight, fragile nature and poor heat insulation/reflection properties used to make it somewhat impractical.

Now all that has changed. K2 has developed a unique range of performance glass specifically engineered for use in conservatory roofs. Known as Celsius, this glass has a unique micro-coating which enables it to deflect excessive heat from the sun away from the conservatory and to reflect heat from inside the home back into the property. In this way, Celsius keeps conservatories warm in winter and cool in summer, helping to create a room for all seasons.

Further benefits include increased sound insulation, a subtle blue tint to minimise glare and a special easy clean coating which reduces the need for manual cleaning. Plus, with Celsius, you enjoy a clear view through the roof and benefit from the feeling of light and space that a glass roof brings.
