We have been using the Alitherm Aluminium Conservatory Roofing System for a number of years for its appealing soft lines. The Aluminium extrusions have a Polyamide Thermal Break. All roofs are factory assembled before despatch. Any RAL colour is available to choose from. Delivery of these roofs is approximately 4/5 weeks from signed acknowledgement and can be supplied glazed or un-glazed.

25mm or 35mm Polycarbonate Glazing is available with several options namely Clear, Bronze, Opal or Heatsheild, the latter helping greatly with heat retention and deflection of harmful rays.

24mm Toughened Safety Glass Sealed Units are a more common method of Conservatory Roofs and they are available in Clear, Bronze, Grey, Green and Blue. More and more people are having the very popular ‘self’ cleaning glass in Clear or Blue Tinted.

Below is a table defining the benefits of the Celsius Performance Glass.

Heat Reflection: 78% 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 Protection: 94% Reduces the effect of harmful UV rays allowing greater protection of your furniture and fabrics.
Easy Clean The Easy Clean coating reduces the requirement of manual cleaning as it enables water to run off the glass taking most of the dirt and grime with it.
Visible Light Transmission: 38% Celsius Elite softens the impact of natural light through the roof of your conservatory for increased comfort.
