Patent GB2636232: BalcoDeck® - UK's only patented non-penetrative balustrade
What it took to engineer the UK's only non-penetrative balustrade and decking system - and why the industry hadn't done it before
What a granted patent actually means.
A UK patent grant is not a reward for a good idea. It is a legal finding that an invention is new, involves an inventive step, and is capable of industrial application. The UK Intellectual Property Office does not grant patents to things that already exist, to things that an engineer skilled in the relevant field would find obvious, or to things that have no practical utility.
Patent GB2636232 was granted to BalcoDeck® in January 2026. Development of the system began in 2022. The patent was filed in early 2024 - and it is worth understanding why that sequence matters: under patent law, publicly disclosing an invention before filing invalidates the claim, as the invention is deemed to have entered the public domain. BalcoDeck® could not be marketed, supplied or publicly described in technical detail until the patent was filed in 2024. Commercial supply began after that filing. The grant followed in January 2026, confirming the IPO's finding that the invention was new, involved an inventive step, and was capable of industrial application.
What that means in plain terms: the IPO examined BalcoDeck®'s engineering, considered everything that had existed before, and concluded that this specific approach - the geometry of the platform, the mechanism of load distribution, the way the system works with a finished membrane surface - had not been done before and would not have been obvious to a structural engineer working from existing knowledge.
In a field where most product development consists of incremental improvement to existing systems, a granted patent in structural building products is substantive evidence of genuine technical novelty.
The novel claim: what the patent actually protects
To understand what is novel in GB2636232, it helps to understand what was not novel - what the prior art looked like before BalcoDeck®.
Non-penetrative approaches to placing weight-bearing structures on flat roofs were not unknown. Rooftop plant, HVAC equipment, and solar arrays have all been placed on flat roofs using ballasted or gravity-fixed support systems for decades. The engineering for those applications - calculating self-weight requirements, managing bearing pressure, accommodating roof falls - is established.
What was genuinely novel was doing this for a balustrade system: a structure that must resist significant horizontal and uplift loads imposed by wind and occupant interaction, at a height of up to 1.1 metres (and sometimes 1.8m when privacy screens are used) above the platform, with the structural forces therefore producing large overturning moments at the base, while maintaining bearing pressure within membrane tolerance limits, while meeting BS 6180 barrier performance requirements, while accommodating drainage falls, while providing a level deck surface for occupants above.
The challenge for a ballasted plant platform is primarily about vertical load. The challenge for a balustrade platform is primarily about overturning moment. Those are fundamentally different structural problems, and the platform geometry that solves one does not solve the other. The BalcoDeck® patent covers the specific structural geometry that solves the overturning moment problem within the membrane tolerance constraint - and that is what had never been done before.
The innovation barriers: why it took until 2024 to file
If the waterproofing problem with penetrative balustrade fixing was so well understood - and it was, architects, specifiers and waterproofing contractors had been aware of it for twenty years - why did it take until 2022 for anyone to begin developing a patentable solution, and until early 2024 to file one? The answer has three parts.
The first is commercial. Every established balustrade company in the UK was selling penetrative systems. Their manufacturing processes, installation training, product libraries and NBS clauses were all built around penetrative fixing. Developing a non-penetrative system from scratch would have required cannibalising an existing revenue stream to create something new with an uncertain market - a calculation that most established players would not make.
The second is technical. The engineering of a non-penetrative balustrade platform is genuinely non-trivial. It requires simultaneous optimisation across structural mechanics, membrane behaviour, drainage geometry and weathering performance. A company without deep manufacturing capability and in-house structural engineering would not have been able to execute it even with the commercial will to try.
The third is cultural. The penetrative approach had been industry standard for so long that it had ceased to be questioned. It appeared in every standard specification clause, every training programme, every installation manual. The assumption that a balustrade must be fixed through the membrane was not stated as an assumption - it was simply the way things were done.
Our founder, Effi Wolff, had thirty years of structural glass and aluminium manufacturing experience when he set out to find a better way in 2022. The two-year development process and the resulting patent are the product of that depth of industry knowledge applied to a problem the industry had stopped trying to solve.
What GB2636232 means for specifiers today
The practical implications of a granted patent for architects and specifiers are straightforward.
BalcoDeck® is the only UK system that can legitimately claim patent protection for a non-penetrative balustrade and decking solution. Any other supplier offering a superficially similar approach should be asked - in writing - whether their system infringes GB2636232 and what their legal position is.
The system's technical claims have been independently examined and found to be genuinely novel and non-obvious. This is substantive third-party validation of the engineering, not marketing language.
The Certificate of Compliance BalcoDeck® provides at installation - covering structural loads, wind loads, fire rating, building regulations compliance and material specifications - is backed by a system whose core engineering has been verified at patent examination. That is a different level of assurance from a standard product certification.
The industry has accepted penetrative balustrade fixing as the default for twenty years. GB2636232 is evidence that the default was wrong - and that the engineering to do better has now been done.
