Polycarbonate roofing - the great insulator
Light, tough polycarbonate sheeting for your conservatory roof is a great option. The sheets have almost 200 times the impact strength of glass, and are long-lasting, safe and secure. Polycarbonate sheeting also reduces condensation and diffuses light, and is a great insulator.
You’ll need to consider a number of options for your polycarbonate roofing. We can advise you on this, although the direction your conservatory faces is the main factor. If you are interested in just buying polycarbonate sheets, then these are available for purchase online through our sister company, Truly PVC Supplies, who supply a range of conservatory, window and door parts..

The range benefits from:
- Testing to Class 1 Spread of Flame Protection
- 10 year warranty for light transmission and breakage
- Superb thermal efficiency and strength due to the 5 and 6 wall construction.
Explanation of Glass and Polycarbonate Features
- Self Clean
- Coating that reacts with sunlight to break down dirt on the surface. In addition rain 'sheets' away quickly, rather than forming droplets and leaving unsightly ‘drying spots’.
- Solar Control
- Helps regulate the amount of solar energy that enters a conservatory. Provides a more comfortable and energy efficient conservatory.
- Low E
- Low emissivity cloating applied to the external face of the internal pane helps to reflect heat back into the conservatory.
- Solar Transmission
- The proportion of the Suns energy that is transmitted through the glass or polycarbonate sheet. The lower the percentage the better it is.
- Argon Gas
- Gas filled cavity reduces the transfer of heat through the unit.
- U Value
- A measurement to describe the rate of heat transfer from one side of the unit to the other. The lower the better.
- Solar Heat Reflection
- Percentage of heat from the sun that can be reflected to prevent conservatory from getting uncomfortably warm.
- Light Transmission
- Percentage of light that passes through the double-glazed unit or polycarbonate sheet. A lower figure means reduced glare and less risk of sun damage to furnishings.
