Ultraframe Classic roof

If the most important feature of your conservatory is going to be light, a glass or polycarbonate roof system is just what you need. 

For glass roofs the standard specification used is Pilkington Sunshade Blue with self-cleaning and low e coatings. Combining the solar control coating with our energy efficient glass units provides unbeatable thermal insulation, a U-value of 1.0W/m2K, reflecting heat back into the room and reducing heat loss more effectively than traditional low-emissivity glass products. The result? You can have the best of both worlds, our double-glazed units provide - solar control coating on the outer face to keep cooler in warmer summer months, and the thermal retention properties of the low ā€˜eā€™ coating on the inner pane to keep the room warm in the winter.

An alternative to glass is polycarbonate panels, available in a wide range of colours and thicknesses to suit your budget and conservatory colour, polycarbonate can be treated to offer excellent solar protection and thermal properties, with a U-value of 1.7 W/m2K to 1.3 W/m2K dependant on the thickness and colour. One of the ways in which the thermal properties of the polycarbonate can be increased is by using a layer of foil inserts inside the polycarbonate panels which will increase the solar rejection therefore lowering the u-value. However, this is at the cost of light transmission, while Pilkington Sunshade blue glass is 80% and polycarbonate varies from 8% to 51% depending on the colour chosen.
