14 Jun Sotech reveal advanced hook on secret-fix rainscreen system, Optima FC+
An evolution of the Hook-on Secret Fix Rainscreen solution
Sotech has today unveiled an evolution of its original hook on secret fix rainscreen solution, Optima FC. Featuring an innovative slide and lock adjustment mechanism, carrier rail hooks can now be locked in position on site by installers, rather than in the factory, leading to significantly reduced lead times for all parties.
Named “Optima FC+”, the improved system is an evolution of Optima FC – a hook-on secret fix rainscreen system.
“The industry has evolved a lot over the past three years”, said Charlie McLaughlin, Specification Manager at Sotech, “It’s important our customers and the people who eventually use the buildings understand that we not only provide fire-tested systems but that we provide high quality systems at the right price and in the right timeframe.
“The introduction of the slide and lock adjustment mechanism has given the original FC hook on system an incredible time-saving benefit and it reflects Sotech’s unwavering commitment to safety, performance and efficiency. We’re really pleased with the turn out of the new FC+ system and look forward to seeing it on buildings this year. Customers still have the option to order pre-assembled rails.”
Is FC+ tested?
FC+ has been successfully fire tested to BS8414. Classified to BR135, Optima FC+ is safe to use on high rise buildings in conjunction with Euroclass A1 and A2 – s1, d0 fire rated materials. Sotech has always been at the forefront of testing in the rainscreen facade industry, fire testing since 2006. For more information on how Sotech can help with large scale fire tests click here.
CWCT Tested and certified at Vinci Technology Centre.
“Our motivation was to provide true A1 and A2 rainscreen systems in the slickest timeframe possible”, said Graham Todd, Director at Sotech, “Providing safe, reliable fire-rated systems is our priority. Ensuring they are produced cost effectively and can be installed quickly is of huge importance to our customers and our place as leaders in the market. With FC+ rolling into production, we’re turning our attention to upgrading the original TFC in the same way.”
In addition to the new slide and lock mechanism, Sotech now uses mechanical fixings for mid-point support and panel stiffening, removing the need for glue and making the system truly A1 or A2, as required.
Sotech has always prided itself on its history of testing.
“Our testing covers 99% of all jobs”, added Graham, “We choose our build ups carefully to achieve a constant. Where customers want to test systems for specific projects, we’re happy to help and can test build ups to BS8414”.
What is hook on rainscreen?
Hook on rainscreen facade is a fully draining, back ventilated façade. This provides a significant advantage as panels can be installed top down or bottom up and can be removed individually, without disrupting other panels.
The secret fix rainscreen solution is also better ventilated than most rainscreen solutions and serves its primary function of stopping the force of wind-driven water movement incredibly effectively.
The system has the flexibility to be used in a portrait or landscape orientation and carry a multitude of panel material thicknesses on the same universal carrier rail.
Optima FC+ is an evolution of Optima FC, Sotech’s original and best-selling secret fix hook on rainscreen solution for largescale projects in the UK.
How does FC+ work?
With the new moving hook system in FC+, the ‘hooks’ are kept separate and sent loose to site. The hooks can then be added to the rails on site and moved easily up and down a specially created channel before being locked securely in place with the turn of a bolt. This more user-friendly approach can save weeks in the design and manufacturing stage, removing the need for ‘more permanent’ drilling and screwing and it also minimises mistakes as the hooks are positioned on site, by installers.
Whilst the option is available to have the hooks pre-loaded in the factory it is the customer’s choice if they wish to do so.

Is FC+ in use currently?
FC+ is currently being installed at Kelaty House at Wembley. Installers Conneely Facades chose FC+ over the original FC because of the tight turnaround times involved in the large scale project.
Because of the size of the project, Sotech completed testing in house on large testing rigs to ensure all parties were happy with the installation process and performance.
