Marmox Multiboard Tile Backer Board (600x1200mm)

Marmox Multiboard 600 x 1200mm (All Thicknesses)

Waterproof | Insulating | Load-Bearing | Tile Backer Board> for Internal Use

The Marmox Multiboard (600 x 1200mm) is a high-performance tile backer board designed for internal use on walls, floors, and ceilings. Suitable for both domestic and commercial settings, this board offers an unbeatable combination of waterproofing, thermal insulation, and mechanical strength. It provides an effective decoupling layer between tiles and substructures, helping to prevent cracks caused by substrate movement while supporting heavy tile installations.

Key Benefits:

• Lightweight: Easy to handle and install, reducing labor time.
• Waterproof: Impermeable to water, acting as a moisture barrier, making it suitable for wet areas like bathrooms and kitchens.
• Thermal Insulation: Provides excellent thermal resistance (R-values from 0.11 to 1.67 m²K/W, depending on thickness), unaffected by temperature variations, including freezing conditions.
• Chemical and Heat Resistance: The cementitious surface is resistant to heat and chemicals in the sheathing of electric underfloor heating systems, ensuring safe use.
• Easy to Cut: Can be cut in straight lines with standard tools for precise fitting.
• Enhanced Tile Adhesion: Provides a strong base for tiling or plaster finishing, serving as an alternative to laminated thermal plasterboard.
• High Load Capacity: Supports over 100 kg/m² on walls and 40 tonnes/m² on floors, depending on adhesive and substrate.
• Flexible Orientation: Boards can be aligned horizontally or vertically to suit project needs.
• Safe and Sustainable: Contains no hazardous substances, with zero ozone-depleting potential (ODP) and a low global warming potential (GWP) of 0.29.
• Certified Quality: Manufactured to ISO 9001 Quality Management Systems, BS EN 5385-2, and CE marked to EN 13164.
• Sound Insulation: Offers impact sound reduction of 21 dB (to BS EN 140-8).

Applications:

• Wet rooms, bathrooms, and kitchens
• Underfloor heating systems
• Insulated internal walls and ceilings
• Over timber, concrete, plywood, chipboard or OSB substrates
• Construction of bathroom furniture and shelving (with thicker boards)
• As an alternative to thermal plasterboard (can be plastered or tiled over)

Storage and Installation

• Storage: Store boards flat and cover joints with scrim/reinforcing tape to ensure stability.
• Installation: Consult manufacturer’s literature for detailed fitting instructions specific to different substrates (e.g., concrete, plywood, plasterboard, timber/metal frames). Boards can be fixed with adhesive or mechanically, depending on the substrate and application.

Fixing Options Based on Substrate:

Marmox Multiboard can be securely applied using adhesive, mechanical fixings, or both depending on the surface. It is suitable for:

• Concrete floors
• Timber/metal frames (at 300, 400, or 600 mm centres)
• Plywood or OSB flooring
• Plastered or uneven block walls
• Raised access flooring
