Optima TFC+ is a high-performance through-fix cassette rainscreen cladding system developed by Sotech. Designed as a cost-effective alternative to secret-fix systems, it delivers a clean, contemporary façade appearance with visible fixings discreetly recessed into vertical joints.

It is suitable for high-rise and complex buildings, having passed BS 8414-2:2015 fire testing and achieved BR 135 classification, confirming its compliance with UK fire regulations. Optima TFC+ is also CWCT tested for weather resistance and structural integrity.

The system supports a variety of non-combustible metal finishes, including aluminium, zinc, copper, and stainless steel, and is available in panel thicknesses from 2mm to 4mm. Its drained and ventilated design promotes moisture management and thermal performance, while advanced manufacturing ensures precision detailing.

Optima TFC+ is widely used in modern architecture for its safety, durability, and design flexibility.
