For ultimate re-assurance we produce Certificate of Authenticity that allows the homeowner to register the glass in their conservatory installation direct with Celsius - your certificate should be supplied to you by your Installer. (Only available for installations purchased after January 2011.)

Ensure that you have received genuine high performance Celsius glass by registering your product online.

By entering the supplied reference numbers (circled in red on the image) into our Register Your Glass page, your information is checked against our order database, and if we have any concerns about the authenticity of your glass, we'll contact you.
