Alumil SF 85 SUPREME Folding System – Premium Folding Doors with Kooltherm Barrier

The Alumil SF 85 SUPREME folding system is the reference in the aluminium folding systems segment, combining the 85 mm construction depth with the 40 mm Kooltherm thermal barrier — an insulating material with conductivity λ ≈ 0.022 W/mK, significantly superior to standard polyamide (λ ≈ 0.25 W/mK). This combination ensures Uf from 1.0 W/m²K for a folding system, performance at the level of many fixed window systems. PAS24 anti-burglary certification — the most demanding British standard for oscillating and folding systems — guarantees protection even in the 8-panel variant, where each joint represents a potential vulnerable point. The system adapts to openings from 1 m to 7 m width, with 2 to 8 panels configurable to the left, right or with 90° corner pivot, allowing simultaneous opening of two perpendicular facades — the defining architectural solution for bars, restaurants, hotels, car showrooms and luxury villas. Neofort BIZ designs and installs SF 85 SUPREME with complete structural calculation and production warranty.
