ISOVER Polterm Max Plus
ISOVER Polterm Max Plus non-combustible 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 a Euroclass A1 Reaction to Fire classification, according to BS EN 13501-1.
When specifying the exterior of the building, it's important to ensure that the facade looks perfect, but that underneath needs to be an insulation product that you know works best for your project.
With ISOVER Polterm Max Plus, it's one big plus after another as this insulation solution boasts a range of features which make it ideal for rainscreen and masonry façades.
The stone wool insulation offers both thermal and acoustic benefits, whilst also being BBA certified (19/5672) and achieves a Euroclass A1 Reaction to Fire classification (according to EN 13501-1).
Polterm Max Plus also contains a water repellent additive to limit water absorption. What stands out though is the black glass veil, contributing to the aesthetics of the installation, as it prevents any ‘show through’ of the insulation from behind the façade system.
With a thermal conductivity o 0.035 W/m.K, Polterm Max Plus will help reduce heat loss within the building envelope and decrease energy costs*. Slabs can be tightly butted together and the inner face will accomodate substrate irregularities to maximise thermal performance in situ.

Celotex products should not be used in the external walls of buildings over 18 metres in height (England and Wales) or 11 metres in height (Scotland). Recent changes to Building Regulations mean that only non-combustible insulation or insulation of limited combustibility can be used in buildings of that height.
