Isover launches new non-combustible insulation

Isover has launched a new stone wool insulation, Polterm Max Plus, for rainscreen cladding and over-cladding applications.

Polterm Max Plus is a non-combustible 1200 x 600mm stone mineral wool slab, which delivers excellent thermal and acoustic performance, while achieving the best attainable A1 Euroclass fire classification according to EN 13501-1.

With a thermal conductivity of 0.035W/mK, Isover’s new range will help reduce heat loss within a building; the slabs can be tightly butted together, while the inner face accommodates substrate irregularities, to maximise the thermal performance.

In addition to its thermal performance, Polterm Max Plus will also improve the acoustic performance of the external envelope, reducing the airborne noise from aircraft, vehicles, trains and weather.

Polterm Max Plus contains a water repellent additive to protect against moisture ingress during installation.

The black glass veil on the external facing side of the insulation contributes to the aesthetics of the installation, as it prevents unwanted sightings of the insulation from behind a ventilated rainscreen façade system.

Stuart Dumbarton, Head of Product Management at Isover, commented: “The launch of Polterm Max Plus demonstrates our commitment to continually improving our product offer with solutions that add value for our customers.

“Polterm Max Plus can be used in conjunction with our Steel Frame Infill Batt, which is designed to fully fill the steel frame stud and provide additional thermal and acoustic performance.”

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