The market for solid, insulated roofs is growing strongly, yet there is a gulf in performance between all the major systems explains Prefix Systems, the UK’s largest independent specialist for the extended living market.

The combination of product design and materials used makes their own Garden Room roof the stand out product in the sector. It’s structurally robust, thanks to the use of the structural grade of 6082 aluminium alloy and not the inferior general grade of 6063 which is used on other solid roof systems in the market. Furthermore, fixed joints are part of this unique design and are necessary in such structures at the eaves and ridge to accommodate the additional weight loading.

The Garden Room roof was several years in the development with Prefix’s own structural engineer Tim Harris and has been designed as a roofing platform for the future, as the recent contemporary Urban Room roof that shares the same chassis ably shows. There are also further developments planned for early 2016 and in time for the FIT Show.

Beyond material specifications and fixing detail, configurability is as equally important, particularly given the prominence of the replacement conservatory market. A conservatory by design is different to that of a typical extension and therefore insulated, solid roofs need to be equally adaptive. For this reason the Garden Room roof has been designed to cater for valleys, large span box gutters and pitches from 5 to 40 degrees. Even drop valleys, different height ridges and spans up to 6 metres can be incorporated.

Chris Baron, co-director at Prefix Systems commented: ‘Our customers are telling us that most solid, insulated roofs have a limited market by design and indeed many aren’t prefabricated to the required standard. It’s for this very reason we’ve spent considerable resources in developing what is the most structurally sound and configurable roof in the sector.

He continues: ‘Installation companies looking for the most robust and fitter friendly solution should look at Garden Room, it’s our platform for the extended living market for the future.’
