Window Glazing Options

Performance Conservatory GlazingTypically for the windows, most clients choose from either Standard Clear Toughened Glass or Performance Glass. Performance Glass utilises a Low-E and Solar Control combination coating with an Argon Gas filled cavity. This helps to control the amount of visible light, UV and heat that pass through the glazed unit. A self-cleaning coating is added to all performance glass units.

Performance Glass Unit Construction

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.

Celsius One™

Celsius One Conservatory Roof Glazing
The roof of this beautiful gable conservatory shows off the full effect of the blue tint.

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.

Conservatory Roof Glass Heat Reflection Heat Reflection 78% Celsius One reflects approximately 3 times more solar energy than standard glass.

Celsius Elite is the ultimate in performance. Keeping you cooler in Summer and warmer in Winter.

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.

A stylish conservatory fitted with Celsius Clear glass.

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.
