Aluminium cover sheet –
KAPA®tech
KAPA®tech is a light and rigid fire-retardant sandwich panel consisting of PUR foam core and aluminium cover sheets. The material’s fire classification in accordance with the EN 13501-1 standard is class B, s2, d0. Being weather- and moisture-resistant, the material is suitable for indoor and outdoor use and as an insulation material. It has a protective film on both sides. It has been approved for use in ships (MED approval) and in the train manufacturing and construction industries. We deliver KAPA®tech as composite sheets.
