Tile backer board for external use.
Carrier element for fixing ceramic and stone tiling and brick slips to external walls. Provides thermal insulating and waterproofing.
Waterproof, thermally insulating tile backer board for external use. An internal board is available, specified separately.
Features and benefits:
- Lightweight.
- Dimensionally and structurally stable in all weather conditions.
- Resistant to freeze-thaw damage.
- Provides an effective decoupling layer between the tiled surface and the substructure.
- The surface allows heavy weights to be safely and securely fixed to walls.
- Impermeable to water, and acts as a moisture barrier.
- Thermal insulation is unaffected by various temperatures.
- The cementitious surface is resistant to heat and chemicals.
- Can easily be cut in straight lines.
- Provides enhanced tile adhesion.
- Load bearing capacity exceeds 100 kg/m².
- Boards can be aligned horizontally or vertically.
- Does not contain any hazardous substances.
- Manufactured in accordance with ISO 9001 Quality Management Systems and BS EN 5385-2, and CE marked to EN 13164.
Boards should be stored flat and covered with scrim/ reinforcing tape. For fitting instructions onto different types of substrate, consult manufacturer's literature.
