6mm Swisspearl Construction HD Board - Fibre-Cement Building Board - 1200mm x 2500mm

6mm Swisspearl Construction HD Board is a strong, durable, high-density, fibre-cement building board designed for demanding applications in both interior and exterior environments. Manufactured with a raw, untreated finish and a natural grey tone, it offers a clean, cementitious aesthetic suitable for modern architectural designs.

Note: formerly known as Cembrit HD

CHARACTERISTICS

• Homogeneous fibre-cement with a cementitious appearance
• Performs reliably in extreme climates; resistant to rot and fungal growth
• Non-combustible with excellent fire behaviour values
• Impact-resistant, dimensionally stable, and long-lasting
• Can be left untreated or coated with diffusion-open masonry or concrete paint
• Low-maintenance surface that does not require repainting over time
• Classified as non-combustible, typically under Euroclass A2-s1, d0 depending on installation and substrate

APPLICATION

Ideal for use in:

• High-performance cladding systems
• Interior wall linings in moisture-prone or high-traffic areas
• Substrates for ventilated façades
• Design-led architectural features requiring a raw, industrial look

INSTALLATION

Substructure Compatibility

• Aluminium or Steel Subframe: Use rivets or facade screws depending on substrate type.
• Timber Subframe: Use Swisspearl Wing Screws; no pre-drilling required.

Fixing Method

• Fixed Point: Secures the panel and prevents movement.
• Sliding Points: Allow for thermal expansion; placed in pre-drilled holes with larger diameter.

Fastener Distances:

• Minimum 20mm from panel edge
• Minimum 60mm from corner
• Spacing depends on wind load and panel size.
  

Panel Layout & Jointing

• Maintain open joints for rear ventilation
• Use vertical battens for support
• Allow for building dilatation and movement
• Ensure ventilation cavity behind panels (min. 20mm)
• Use diamond-tipped tools or fibre-cement blades
• Seal cut edges if exposed to moisture
• Avoid damaging the panel surface during handling
