External wall solutions

We offer an extensive variety of exterior products, including our Knauf ThroughWall system and Knauf AQUAPANEL® Outdoor Cement Boards.

Choose our BBA-accredited ThroughWall exterior infill panel system for optimum quality. This 'through the wall' exterior system offers a full system performance warranty, comprising Knauf components including plasterboards and steel framing sections. Designed to meet high building performance standards, our Knauf ThroughWall system allows for the addition of exterior finishes such as rainscreen cladding or masonry, and it meets exacting standards for structural, fire, thermal and acoustic performance.

Flexible by design, Knauf AQUAPANEL® Cement Board Outdoor is a robust render carrier for external walls and soffits. Knauf AQUAPANEL® Cement Boards are ideal for HRMO (High-Rise Multi-Occupancy), education and healthcare projects where safety, durability and regulatory compliance are critical.

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

Knauf ThroughWall is a one-brand solution that provides the integral parts of a non-loadbearing infill exterior wall system. It comprises Knauf Plasterboards, Knauf Steel Framing Sections, Knauf Insulation products, and Knauf Windliner.

The Knauf Steel Framing System options included in ThroughWall offer a simple construction method which creates a weathertight external envelope with rapid build speeds. This allows internal work to start sooner, fast-tracking the overall construction programme. 

In cladding and masonry façades, our Rocksilk® RainScreen Cavity Systems include cavity barriers and fixings, paired with our non-combustible*** insulation for walls, that is suitable for any building of any height.

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. Supafil® 34 is injected directly into the cavity through pre-drilled holes and has a thermal conductivity of 0.034 W/mK at the recommended density of 25kg/m³.

Meanwhile, Knauf ThroughWall exterior wall systems can be specified to suit your project, ensuring that both the required level and type of sound insulation are accounted for.
