Marmox Multiboard Insulation Boards - All Thicknesses - 1250mm x 600mm

Marmox Multiboard - The tried and trusted construction material that combines water resistance, insulation, and structural strength into a reliable, BBA certified board. Lightweight and easy to cut with minimal dust, it is ideal for tiling, plastering and rendering, both indoors and outdoors.

These boards are made from extruded polystyrene foam (XPS), which is reinforced with a fibreglass mesh and then embedded in a cement polymer mortar, covering both sides.

Key Features

• FULLY WATERPROOF
  No water at all can be absorbed into the core and Multi Board won't warp or degrade in wet areas
• HIGH INSULATION
  10mm and thicker boards are CE-marked, rigid, insulation boards with thermal conductivities between 0.033 to 0.036W/mK
• TILE, PLASTER OR RENDER
  Can be covered with multiple different finishes. BBA certified to accept tiles, plaster or render
• LIGHTWEIGHT & EASY TO CUT
  Significantly lighter than most alternative boards, such as cement-based boards or plasterboard, allowing for easy installation
• LOADING CAPACITY EXCEEDS 100kg/m2
  Marmox Multiboards fixed to a masonry wall, with a continuous bed of tile adhesive, can achieve loading capacity exceeding 100kg/m²
• NO TANKING MEMBRANE REQUIRED
  The XPS core of Multi Board is entirely waterproof and requires no additional tanking membrane in wet areas. All joints should be sealed with Marmox waterproof tape
• EFFECTIVE DECOUPLING
  The combination of the rigid outer shell and the XPS core, which absorbs lateral movement, makes Multiboard an effective decoupling layer
• IDEAL FOR UNDERFLOOR HEATING
  Marmox Multiboards are widely used with underfloor heating systems. They can be laid over the subfloor, providing both insulation and a stable surface for the heating elements. They help to distribute heat evenly across the floor, enhancing the efficiency of the heating system
• MARMOX LIFETIME GUARANTEE
  The Marmox product range comes with a Lifetime Guarantee for total peace of mind
