5. Thermal & Acoustic Properties:
Thermal Conductivity (λ): ~0.15 - 0.20 W/(m·K) - Provides basic insulation.
Acoustic Performance: Contributes to sound reduction in wall/ceiling assemblies (STC ratings vary by system design).
6. Environmental & Health:
VOCs: Zero VOC emissions (tested per ISO 16000, AgBB).
Formaldehyde: Free (< Detection Limit - EN 717-1, JIS A 1460, ASTM E1333).
Asbestos & Heavy Metals: Free (tested per relevant international regulations).
Recyclability: Inherently recyclable mineral content.
Sustainable Sourcing: Primary raw materials from abundant natural minerals.
7. Surface & Workability:
Surface Finish: Smooth, low-dust factory finish ("PureGuard Treated" for improved adhesion).
Machinability: Easily cut, routed, drilled, and shaped with standard woodworking tools (minimizes silica dust vs. cement boards).
Adhesion: Excellent substrate for direct application of tiles, renders, plasters, paints, and veneers.
8. Certifications & Compliance (Examples - Specific to Manufacturer):
Fire: EN 13501-1: A1, ASTM E84 Class A, BS 476 Parts 4, 6, 7, 11, UL Certification (System dependent).
Structural: EN 12467, ASTM C1288 / C1325.
