The cost effective rainscreen solution requires discreet colour match wafer head fixings in the vertical panel recesses. Superior manufacturing techniques ensure accuracy of panel’s size and form leaving even recesses and cruciform of pristine appearance.
Optima TFC has been developed as an economical alternative to a complete secret fix rainscreen.
Whilst being the most economical rainscreen solution, requiring discreet fixings in the vertical panel recess, the engineering of the system retains the benefits of a drained and ventilated façade. Superior manufacturing techniques ensure there will be no build-up of metal thicknesses at the cruciform joint.
The system has been independently tested and certified to meet CWCT rigorous specification for rainscreen cladding.
This drained and ventilated system consists of a baffle-jointed series of panels that creates a weather shield in front of a primary structure.
Optima TFC is engineered to seamlessly integrate with all other building façade elements such as windows, doors and louvres. All fixings used in the systems are stainless steel.
Sotech has completed fire testing on Optima TFC at BRE, Watford. Optima TFC has been tested to BS8414-2 and is compliant to BR135:2013.
Optima TFC has been successfully tested to BS8414 and classified to BR135. Please expand the tabs below for full details and report downloads.

Sotech were engaged by Charles Henshaw to produce over 1600 square meters of rainscreen cladding for Statoil’s (the Norwegian oil and gas major) new 60,000 square foot HQ located on the Prime Four Business Park at Kingswell, just west of Aberdeen. The new Statoil House has been built to Statoil’s specifications by UK building and civil engineering company Sir Robert McAlpine under a contract with park developers Drum Property Group.
The Sotech Optima FC system was selected for the project due to the precise coordination between panel and substructure that presents a pristine appearance without the use of visible fixings. TFC was also selected as accurate installation is both simple and speedy. In addition to the traditional systems, Sotech designed bespoke window and cill panels, which were designed to add depth to the façade.
Accurate installation is both simple and speedy as there is no precise coordination between panel and substructure as there would be with a hook on system.
Consistency of colour, the cassette recesses are formed from the face of the material.
Inspection or damaged panel removal is possible by loosening adjacent panels.
NHBC and LPCB accredited including a red book entry.
Shows 20mm standard joint between panels. Joint size can vary but 15mm minimum.
A fully independently tested and accredited system to CWCT standards.
Easy installation, refer to installation guide for wall type build up
Panels can be fixed to a simple top hat or timber baton of minimum 38mm depth to create ventilation with a cladding zone as shallow as 90mm.
System allows ventilation zone to be minimum stipulated by CWCT.
Panels are fixed using wafer head, self-tapping stanless steel screws through pre-punched holes.
Consult Sotech regarding structural restrictions, and constraints relating to panel size, fastener type frequency of fixings.
Easy installation, refer to installation guide for wall type build up
Suitable for all types of wall constructions either new build or refurbishment
A fully adjustable system.
Varying lengths of hands free brackets together with angles and tee profiles allows adjustability in all planes to line and level cladding zones from 110mm above insulation thickness to a maximum of 320mm.
Panels are fixed using wafer head, self-tapping stainless steel screws through pre-punched holes.
Ventilation zone behind panels often has to exceed CWCT minimum requirements to accommodate structural rails.
Consult Sotech regarding structural restrictions, and constraints relating to panel size, fastener type frequency of fixings.
Sotech’s commitment to authentic engineering capability has been witnessed over several years in the testing of products as they are being developed.
From the earliest designs of the Sotech Optima solid aluminium cassette rainscreen system, Optima TFC, tested at BRE, Garston for wind serviceability and safety, air permeability and water penetration for Erie Basin, Manchester project.
