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.

Our Technical Services team are here to guide you through every step of the process.

Benefits of our external wall solutions

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.

Gypsum for External Walls

In an external wall, the choice of system is critical to achieving the right balance between structural integrity, thermal efficiency, and long-term durability. Knauf offers a comprehensive range of solutions designed to meet the demanding performance requirements of external wall construction, whether for new builds or renovation projects.

External wall systems must address multiple performance criteria simultaneously — from moisture management and fire resistance to airtightness and energy compliance. Knauf's portfolio includes solutions for a wide range of external wall applications, such as steel frame systems, external thermal insulation composite systems (ETICS), steel frame constructions, and cavity wall assemblies.

System solutions

Specification can be complex, particularly for high-rise buildings. Our system solutions help to simplify the specification process.

Fire safety and durability

Fire safety and weather resistance are important for occupant wellbeing and the longevity of your building.

All of Knauf Insulation’s mineral wool slab, roll, and blowing wool products have the highest Euroclass A1 (non-combustible) or A2 (limited combustibility) reaction to fire classifications according to EN 13501-1.

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.

For external full-fill masonry cavity walls, we also offer a glass mineral blowing wool insulation, which is injected directly into the cavity through pre-drilled holes.
