Patented Structural Cassette System

Fortra – the only truly complete,  patented cassette system for orangeries and sunrooms.

Orangery Solutions adopts a more responsible approach to structural integrity, encompassing the entire structure not just the flat roof.

For any orangery or sunroom build to be successful and durable it is imperative that the foundations and core structure have a solid internal core.  For this reason Fortra was created.

New orangeries can be left vulnerable when built using inferior products as they can have far reaching and expensive consequences in the long term resulting in wall cracks with the potential to weaken the entire structure.

Our patented system combines the latest timber engineering technology with galvanised structural steel to provide a fortified final structure from foundation level upwards. Supplied as a complete kit means Orangery Solutions can guarantee the entire structure.

With many years professional building experience Orangery Solutions has developed an original, proven system for premium properties, that will last. No other product on the market can provide the same resistance, guarantees or reassurance when a lateral force is applied.

Importantly, unlike other orangery supply companies WE DO NOT use disclaimers, as we take responsibility for the side walls and roofing system in all our orangeries and sun rooms.
