The replacement conservatory roof sector is booming, but installers must consider installing the Retro-Fix posts from Prefix Systems, given the potential catastrophic events of a structural failure. With tired polycarbonate glazed roofs being replaced with glass or solid, tiled roofs, the additional load bearing must be assessed.

There’s a duty of care to consumers and so the sales, survey and installation process must consider the implications of a heavier roof. To put this into perspective, new glass roofs are typically four times as heavier than a polycarbonate roof and the latest tiled roofs are at least double the weight of a glass roof.

Now celebrating over a decade in the market, Retro-Fix posts have been designed and engineered by Prefix Systems specifically for the conservatory replacement market and they were the first and still the only company with such a development. Customers can liaise with all four Prefix branches, serving the entire UK with any structural queries relating to a replacement project, with the benefit of gaining expert technical guidance on structural requirements.

It's a simple process as whatever the roof configuration, Prefix can offer guidance on the use of Retro-Fix posts. Where they are specified on a project, it’s important to note that they are designed to blend in with the new structure, which makes it a big plus with the consumer from a finished design perspective.

Chris Baron of Prefix Systems commented: ‘With around 3 million conservatories in need of upgrade or repair, we must assess the structural implications of installing a heavier roof in all projects. We’ve got over 10 years’ experience in this and a unique, structurally proven product in the form of Retro-Fix, so why not use our expertise on your next replacement job?’
