Larsen Thermal Construction Board is a versatile lightweight building panel, specifically designed for various applications, including laying different types of tiles, applying cement-based screeds, and synthetic renders. It is produced using high-density extruded polystyrene, which offers excellent insulation properties.

The extruded polystyrene core comes with a reinforced cement coating applied at the factory, providing remarkable impact resistance, sound reduction, and fireproof qualities. This makes these boards ideal for use in construction projects. They can be employed in a wide range of locations, including floors, walls, ceilings, and even countertops, and are particularly suitable for wet environments like bathrooms and kitchens, where walls and floors are regularly exposed to moisture.

Key Features:

  • Simple Installation
  • Excellent Insulation
  • Long-lasting
  • Waterproof
  • Effective Sound Reduction

What is overage?

Overage is a safety to ensure you have enough tiles required for your project. Overage also ensures you have extra tiles to cover you in the event of human error during installation, such as breakages, and so that you can store spares for future use should tiles become damaged over time. This is particularly important as tiles can be discontinued, making it a challenge to match if you don’t have spares of the originals.
