Fortra – strong to the core.
We offer the only truly complete, patented cassette system for orangeries and sunrooms, adopting a more responsible approach to structural integrity and quality guarantees that encompasses the entire structure and not just the flat roof.
We have focused our attention on the entire structure and not just the flat roof combining the latest timber engineering technology with galvanised steel which gives complete peace of mind in terms of the stability of the finished orangery project.
Manufactured in-house we supply a complete kit that comes with solid guarantees which eliminates concerns over common longer term problems such as wall cracks and subsidence.
No other product on the market can provide the same resistance, guarantees or reassurance when a lateral force is applied and we substantiate this with certificates of guarantee.
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.
