Vermiculite Insulation Board is a rigid, high-performance insulation panel manufactured from exfoliated vermiculite, inorganic binders, and reinforcing fibers. It is engineered to provide exceptional fire resistance, thermal insulation, and acoustic damping in a single, easy-to-install product. Ideal for commercial, industrial, and high-specification residential projects, it ensures safety, compliance, and energy efficiency.

• Unmatched Fire Protection: Classified as a non-combustible material (typically A1 or similar, subject to local standards). It acts as a formidable fire barrier, containing flames and limiting smoke spread, thereby protecting structural integrity and increasing safe evacuation time.

• Excellent Thermal Insulation: Low thermal conductivity significantly reduces heat transfer. Contributes to improved building energy performance, lower HVAC operational costs, and enhanced occupant comfort.

• Superior Acoustic Performance: Effectively dampens sound transmission, reducing noise pollution between rooms, floors, and from external sources. Perfect for partition walls, ceilings, and floors in multi-unit dwellings or offices.

• Rigid & Durable: High compressive strength allows it to withstand loads without sagging or crumbling. Maintains its dimensional stability and performance over time under various environmental conditions.

• Moisture Resistant: Inorganic composition makes it resistant to mold, mildew, and rot. It will not sustain vermin, ensuring long-term hygiene and material integrity.

• Easy to Fabricate & Install: Can be easily cut, drilled, and shaped on-site using standard woodworking tools. Available in a range of thicknesses and sizes to suit various framing systems and applications.

• Chemically Inert & Environmentally Friendly: Contains no CFCs, HCFCs, or formaldehyde. Made from abundant natural minerals, contributing to greener building specifications.

• Fire-Rated Walls & Partitions: Core insulation in walls requiring certified fire resistance (e.g., stairwells, service shafts, compartmentation walls).

• Fire-Resisting Ceilings & Soffits: Provides fire protection and thermal insulation in suspended ceiling systems.

• Structural Fire Protection: Encasement of steel beams and columns to meet fire rating requirements.

• High-Temperature Insulation: Used as a protective board behind and around stoves, fireplaces, and boilers.

• Acoustic Walls & Floors: In party walls, home theaters, recording studios, and floor/ceiling assemblies where sound reduction is critical.

• Industrial & Marine Applications: Insulation for ovens, furnaces, and in shipbuilding for fire integrity.
