Description

Wallclad+ is an advanced, engineered version of Wallclad, developed for external wall insulation (EWI) systems and facade applications requiring project-specific performance and enhanced design flexibility. It is designed for use behind render, bonded cladding, and adhesive or mechanically fixed facade finishes.

Manufactured from natural volcanic basalt and compliant with EN 13162, Wallclad+ delivers high-performance thermal insulation, acoustic control, and non-combustible fire protection. Its dense and dimensionally stable structure provides a robust substrate for a wide range of facade systems, including render, brick slips, ceramic tiles, and thin masonry units.

Wallclad+ is fully customisable in density and thickness, allowing facade engineers and designers to optimise structural performance, impact resistance, acoustic properties, and fixing requirements to meet specific project demands. This makes it particularly suitable for complex facade designs and high-performance building envelopes.

Wallclad+ is classified as Euroclass A1 (non-combustible) and is suitable for buildings of any height, including high-rise developments, in accordance with UK Building Regulations.

Typical applications

• Rendered external wall insulation (EWI) systems
• Structurally bonded brick slip systems
• Adhesive-fixed facade cladding systems
• Drained EWI facade constructions
• Ventilated EWI facade systems
• Hybrid EWI cladding systems
• New build and refurbishment projects

Advantages

• Non-combustible Euroclass A1 fire performance
• Suitable for buildings of any height, including high-rise
• Customisable density and thickness for project-specific facade requirements
• Designed for EWI and direct facade applications
• Compatible with bonded, rendered, and mechanically fixed facade systems
• High-density, dimensionally stable structure for robust facade support
• High thermal performance, λ = 0.0364 W/mK (project-specific variations available)
• Excellent acoustic performance
