Polterm Max Plus is a non-combustible stone wool insulation providing thermal and acoustic performance within ventilated rainscreen cladding and overcladding systems.

Polterm Max Plus is a 1200 x 600mm stone wool slab with a black glass veil on the external side.Certified by the British Board of Agrément (BBA), the resilient slabs will provide thermal and acoustic insulation within ventilated rainscreen cladding and overcladding systems. The stone wool insulation is non-combustible, achieving the best attainable A1 Euroclass fire classification according to EN 13501-1.

The range contains a water repellent additive to protect against moisture ingress. The black glass veil contributes to the aesthetics of the installation, as it prevents any ‘show through’ of the insulation from behind the ventilated rainscreen cladding system.

Polterm Max Plus is manufactured to Quality Management Standard BS EN ISO 9001 and in accordance with the CE marking requirements under the Construction Products Regulation and to product standard EN 13162
