The primary benefits of choosing polycarbonate are:
Polycarbonate is also available with optional ‘Heat-Guard’ which further reduces solar heat gain by 50%.
Polycarbonate is available in both 25mm and 35mm thicknesses.
U Value (w/m2k)
Light transmission – the percentage of light passing through the polycarbonate sheet.
Solar transmission – the percentage of the energy generated by the sun that passes through the polycarbonate sheet. The lower the value the better.
U-value – The ability of the polycarbonate sheet to retain heat within the conservatory. The lower the U-value the more efficient it is at retain heat.
Shading Efficiency – the lower the percentage means that more shade will be generated.
In recent years, almost half of all new conservatories were fitted with a glass roof. Our wide range of roof glass options give you the freedom to opt for extra thermal insulation or UV protection.
Typically for the roof, most clients choose from the following glass options:
All of these glass types are supplied for roofs as self-cleaning.
We can supply other glass types, please contact us for further details.
Celsius Performance Glass sealed units are constructed using various layers/components, as illustrated below.
Please note that these are for illustration purposes only, and not exact thickness scales.
Colours are not indicative of actual glass colouring.
Celsius One has become the new benchmark in performance glass for conservatories.
With its blue tint and combined performance, it both enhances the look of your installation and ensures that you can use it for much longer and greater comfort than if you had opted for either a standard clear glass or other blue glass. Because it isn’t all in the colour.
If you really want to make a difference in the way you use your conservatory opt for Celsius One.
|Heat Reflection 78%||Celsius One reflects approximately 3 times more solar energy than standard glass.|
|U-value 1.0||U-value measures internal heat loss, the lower the number, the greater the insulation.|
|UV Protection 94%||Reduces the effect of harmful UV rays allowing greater protection of your furniture and fabrics.|
|Visible Light Transmission 38%||Celsius One softens the impact of natural light through the roof of your conservatory, for increased comfort.|
The ultimate in performance glass, Celsius Elite brings the best performance glazing you can get for your conservatory.
Visually it has the strongest blue in the range, which serves to enhance colours from your garden without darkening the room.
Externally the tint is more visible, giving a warm, cosy feel to your installation when looking in.
Elite is the best option for conservatories that are south facing and in exposed locations, to ensure you can use the room in increased comfort.
|Heat Reflection78%||Celsius Elite reflects approximately 3 times more solar energy than standard glass.|
|U-value 0.9||U-value measures internal heat loss, the lower the number, the greater the insulation.|
|UV Protection94%||Reduces the effect of harmful UV rays allowing greater protection of your furniture and fabrics.|
|Visible Light Transmission34%||Celsius Elite softens the impact of natural light through
the roof of your conservatory, for increased comfort.
Recommended for the conservatory frames, Celsius Clear is the perfect alternative to standard clear glass.
With a neutral tint that will not stop the light coming through, it will however provide much better protection that standard glass and is highly recommended if you are going to use either ELITE or ONE in your roof to ensure your conservatory performs.
If your conservatory is North facing you might consider using Celsius Clear in your roof to allow a good level of light to come through in winter.

The figures shown above are for guide purposes only. Slight variations may occur due to glass specification, time of year, manufacturing tolerance, point of manufacture and type of instrumentation used.
Visible Light Transmittance – This is the percentage of visible light directly transmitted through the glass.
Solar Factor – This is the percentage of total solar energy (or heat from the sun) able to pass through the glass.
U-Value – This is used to measure internal heat loss during cooler periods. The lower the number, the greater the insulation.
UV Transmission – Sun damaging UV rays are dramatically reduced, allowing greater protection of your furniture and fabrics.
Our conservatory roof glass is supplied as standard with a dual action self-cleaning coating which breaks down dirt and washes it away. Water does not form into droplets therefore you can see clearly through your windows (even when it’s raining).
Better still, when the water evaporates it doesn’t leave behind any dirty marks so that your windows and roof stays cleaner for longer.
The self-cleaning coating is fused into the window and lasts the lifetime of the glass unlike ‘spray-on’ coatings which wear off after a period of time.
