Conservatory Conversions


The WARMroof system from Prefix Systems is the most configurable and structurally robust solid, insulated and tiled roof in the UK market, as our exhaustive testing and research has shown. It’s the first off-site constructed ‘warm roof’ of its kind in the sector that has been designed and engineered from scratch. This has ensured that it is the most innovative, desirable, aesthetically pleasing and advanced roof system available for home extensions and conservatory renovation projects.

Our WARMroof system is perfect for conservatory replacement projects as well as new build sunrooms, garden rooms and extensions, due to its innovative and flexible design. It’s also the most configurable and capable in the sector.

Other insulated and tiled roof systems for the home improvement sector have not been designed using the modern and accepted best method of ‘warm roof’ construction. They have chosen the use of ‘cold roof’ construction, which our research has shown can result in the risk of condensation for six months of the year. Structural integrity, warm roof construction, design configurability and ease of installation are the four corner stones of the WARMroof system, which has been designed and engineered by Prefix Systems and is available, along with on-site technical support, from our three separate branches, which serve the entire UK.
