About Celsius Glass Roof Conservatories
More consumers are becoming increasingly aware of the benefits of glass roofing compared with polycarbonate. Aside from aesthetics, Glass tends to have a much longer life span compared to other roofing products and coupled with the ease of maintenance, it is now a preferred option by many discerning consumers.
The Celsius range was one of the first glazing options on the market to offer the unique combination of heat reflection AND thermal insulation, but Celsius has even more benefits.
Rainfall and traffic noise are dramatically reduced when compared to 25mm polycarbonate. The argon gas filled units reduce the noise even further as well as offering greater insulation properties.
With our Celsius One and Celsius Elite products, destructive UV rays are reduced by up to 88%, thus offering protection for furniture and fabrics from sun damage. Additionally Celsius Clear, with its neutral tinted appearance for side frames and certain roof installations, makes the Celsius range the complete performance glazing solution.
Please note: Celsius One has replaced our previous Celsius Blue product, and Celsius Elite has replaced Celsius Plus.

Easy Clean Conservatory Glass Roof
The Easy Clean System comes as standard across the entire Celsius range.
What is the Easy Clean System?
A system for converting ordinary glass into ‘Non-Stick’, Easy to Clean Glass.
What does it mean for my conservatory?
- Stays cleaner longer because it keeps dirt and other contaminates from bonding to it.
- Is easier to maintain because it requires less cleaning. It will reduce cleaning by as much as 70% over standard glass.*
- Does not support adhesion or growth of bacteria, for a more hygienic environment.
- Protects the surface from organic and inorganic contamination.
- Resists staining from hard water deposits whilst maintaining a pristine appearance.
- Eliminates the need for harsh or abrasive cleaning products.
The picture to the left shows a single pane of glass, which has been treated on the left hand side only with our Easy Clean coating.
Easy Clean beads water droplets for the first few weeks following installation, proof of the product having been applied. The blue tint of Celsius One and Celsius Elite glass also emphasises the natural colours of the sky.
*For units installed prior to April 2012, the reduction is as much as 50% over standard glass.
