The GuardianTM roof

The lightweight, insulated GuardianTM roof system was designed and developed over a ten year period and with one purpose – to replace the typical glass or polycarbonate roof that is most commonly used in the construction of domestic UK conservatories.

The main focus was on the dynamics and performance, however the overall weight of the replacement roof, which needed to be installed onto the existing conservatory windows, doors and frames was always a big priority. During the research and development period extensive tests were carried out both for compliance and approval to some very rigorous structural and thermal standards. The result is not only a brilliant product but a very practical solution, one which has become one of the biggest home improvement products for a decade.

The roof system is often installed as a replacement for an existing glass or polycarbonate roof but more and more new conservatories are being fitted with a GuardianTM roof as standard. It’s easy to see why; the home owner is getting a full-blown extension for the price of a conservatory. If there is such a thing as a ‘no-brainer’ this is it.

A bit about us?
