Cladding steelwork, lining ventilation ducts, retrofitting load-bearing structures in Extertal. Boards, coatings, mineral-wool systems.
Unlike fire doors or seals, claddings don't form compartments — they preserve components. The steel beam, the duct, the timber stays geometrically stable under fire for the defined duration. In Extertal, this matters most in car parks where a beam collapse means a section collapse.
What we install in Extertal depends on the structure, appearance and construction phase.
Intumescent coating — for visible steelwork, where boards would interfere visually.

Sprayable, for large-area load-bearing structures in industrial halls where appearance is secondary.
