XPS Tile Foam Backer Boards are a type of building material used primarily in the construction of tiled surfaces, especially in areas prone to moisture such as bathrooms, kitchens, and wet rooms. These boards serve as a substrate for tile installation, providing a stable and water-resistant base. Here are some key features and benefits of XPS Tile Foam Backer Boards:

Key Features:

  1. Material Composition:
    • Made from extruded polystyrene (XPS-100%), which is a closed-cell foam.
    • This material is lightweight yet durable, making it easy to handle and install.
  2. Waterproof:
    • XPS foam boards are inherently waterproof, preventing water from penetrating and causing damage to the underlying structures.
    • Ideal for wet areas where moisture resistance is crucial.
  3. Thermal Insulation:
    • Provides excellent thermal insulation properties, helping to improve the energy efficiency of the building.
    • Reduces heat loss, making them suitable for use with underfloor heating systems.
  4. Load Bearing Capacity: 500k/Pa(50tonnes/m2)
    • Designed to support the weight of tiles and other coverings, ensuring a secure and stable tiling surface.
    • Suitable for use on walls, floors, and countertops.
  5. Versatility:
    • Can be cut and shaped easily to fit various installation requirements.
    • Compatible with different types of tile adhesives and finishes.
