Increase thermal and acoustic performance with cladding and facade insulation

Insulation is an essential part of any cladding and facade system, adding a layer of support to help improve the building’s thermal performance and acoustic comfort. Particularly when dealing with tall, multistorey buildings, your choice of insulation is important – and we’re here to help, with Isover Polterm Max Plus stone wool insulation and GypLyner Xternal System offering a tested solution with a SpecSure warranty for complete certainty.

Take a closer look at the benefits of cladding and facade insulation

Using our stone wool slab facade insulation can help to reduce heat loss within the building envelope, supporting you in achieving the required U-value of an installation. When installed as part of rainscreen and masonry cladding, it also offers advantages in terms of acoustic and fire performance. Let’s look at the core elements.

Thermal insulation

The small pockets within the mineral wool structure trap air, which is a poor conductor of heat, and significantly reduces heat transfer, making mineral wool an effective thermal insulator. Used as part a system to provide thermal insulation, mineral wool can help to improve thermal efficiency and reduce overall energy costs.

Acoustic performance

As part of rainscreen and masonry cladding, Isover Polterm Max Plus has been tested for acoustic performance as part of the GypLyner Xternal system, and can help to improve the acoustic performance of the external envelope, reducing unwanted external noise from sources such as weather, roads, air traffic and rail.

Reaction to fire

The Polterm Max Plus stone wool insulation within our facade and cladding systems is non-combustible, achieving the best attainable European Reaction to Fire Classification of A1 – non-combustible when tested in accordance with EN 13501-1. This insulation is suitable for use in rainscreen cladding systems, and timber or steel frame constructions.

Our cladding insulation can help to create a more comfortable environment inside through thermal and acoustic benefits.

Isover Polterm Max Plus

A stone wool slab covered with a black glass veil on one side, Polterm Max Plus is a BBA-certified solution for thermal and acoustic applications within ventilated rainscreen cladding and overcladding systems.

With a water-repellent additive to limit water absorption, and the aesthetic benefits of the glass veil preventing show-through of the insulation itself, Polterm Max Plus is installed using standard insulation retaining fittings.

BBA Certified

Certified by the British Board of Agrément (BBA Certificate No. 19/5672), the product provides thermal and acoustic insulation within ventilated rainscreen cladding and masonry cladding systems.
