Marmox Board Ultra
Marmox Board Ultra
Marmox Board Ultra is an advanced light weight structural insulation board engineered for combined waterproofing, thermal insulation, and direct tiling applications.
Technical Property | Official Certified Value | Engineering Benefit |
Structural Core Construction | High-density EPS/XPS core with polymer-cement & fiberglass mesh coating | High compressive strength combined with ultra-lightweight structural performance |
Waterproof & Rot Resistance | 100% Impermeable to water, moisture, and capillary action | Completely prevents water ingress, mold growth, and structural decay in wet zones |
Thermal Insulation Performance | Ultra-low Thermal Conductivity ($\lambda$-value) | Minimizes thermal bridging, reduces energy loss, and optimizes underfloor heating |
Tile Adhesion Surface | Polymer-cementitious textured coating (Tile-Ready) | Provides an exceptional mechanical lock and bond strength with standard tile adhesives |
Marmox Board Ultra
Dual Waterproof & Thermal Insulation: Combines 100% water tightness with high thermal insulation values in a single board.
Direct Tile-Ready Surface: Eliminates the need for wet plastering or rendering, allowing tiles to be fixed directly to the board.
Lightweight & Easy to Cut: Significantly reduces dead loads on structures and can be easily cut using a standard utility knife.
High Load & Impact Resistance: Engineered to withstand structural loads and impact on floor and wall applications.
Wet Rooms & Walk-In Showers: Waterproof wall and floor lining substrate for residential and commercial bathrooms.
Internal & External Thermal Wall Insulation: Reduces heating and cooling costs while providing a stable cladding base.
Underfloor Heating Base Board: Directs heat upward into the room and prevents thermal loss into the subfloor.
Architectural Elements & Bath Surrounds: Ideal for fabricating curved walls, vanity units, bath surrounds, and spa benches.
Substrate Preparation: Ensure the base floor or wall surface is clean, dry, level, and structurally sound.
Board Fixing: Install Marmox Board Ultra using flexible cementitious tile adhesive on solid walls/floors, or mechanically using Marmox anchors/washers on timber or metal stud frames.
Joint Sealing: Seal all board joints and corner interfaces using Marmox Waterproofing Tape and sealant to form a continuous watertight barrier.
Tiling & Finishing: Apply flexible tile adhesive directly onto the Marmox Board Ultra surface and install ceramic, porcelain, or natural stone tiles.
