Exterior solutions that deliver comfort and durability

As urbanisation increases*, insulating against external sound sources, such as people and traffic, is more important than ever. And with fire safety and energy requirements tightening, it’s equally important to ensure a safe, thermally efficient building envelope.

Our exterior solutions for masonry, timber, and steel frame construction deliver thermal performance to reduce unwanted heat loss from the building, and acoustic performance to alleviate unwanted external noise. We also offer non-combustible insulation for walls, and products with moisture resistance, to improve safety and durability.

Insulation for External Walls

In an external wall, insulation is required for thermal performance to reduce unwanted heat loss from the building, and acoustic performance to alleviate any unwanted external noise.

Insulation can be used in a variety of external wall applications, such as masonry cavity walls, external block walls or rainscreen façade systems.

Thermal and acoustic performance

Good thermal and acoustic performance are essential for maintaining a comfortable indoor environment.

Knauf Insulation’s solutions for walls deliver thermal performance in full and partial-fill masonry cavities, timber frames, and rainscreen façades. Our mineral wool insulation is flexible, allowing it to adapt to minor imperfections in the substrate and fully fill the space. This helps to reduce air gaps and maximise thermal performance.

Mineral wool is also the most effective insulant for reducing sound transmission and reverberation, resulting in a more peaceful indoor environment.
