Building Boards | Wall Boards | Backer Boards
Building boards are a fundamental element in both interior and exterior construction projects, offering solutions for walls, floors, and ceilings across various environments. Their multifaceted applications range from providing a sturdy base for tiling in wet areas to enhancing fire resistance in safety-critical spaces.
What is a Building Board?
Building boards are engineered sheet materials used in construction to provide structural support, surface finishing, insulation, fire resistance, or moisture protection. Available in a range of materials like chipboard, OSB (Oriented Strand Board), fibre cement, and gypsum, they’re essential in everything from subfloors and lofts to partition walls and ceiling linings.
Tile Backing Boards
Tile backing boards like the Hardiebacker 500 and Cembacker ensure a moisture-resistant and durable surface, ideal for bathrooms and kitchens. These boards are essential for preventing tile cracks and water damage, ensuring the long-term integrity of the tiled surface.
Fire Protection Boards
The Kemwell FP-900 and MP-1000 series are specialised boards designed to enhance fire safety. With superior fire-resistant properties, these boards are suitable for use in commercial buildings, industrial spaces, and areas where fire safety is paramount. They can be used to protect structural elements, as well as for constructing fire-rated partitions.
Weather Resistant Boards
Products such as the Kemwell WeatherKem and Siniat Weather Defence Board are engineered to withstand the elements, making them perfect for exterior applications. They provide a weatherproof layer in facade systems and are ideal for buildings exposed to harsh weather conditions.
Acoustic and Cement Boards
Quietstone CR Cement Board is tailored for projects requiring soundproofing in addition to durability. These boards are often used in construction projects where noise reduction is a priority, such as in schools, hospitals, and high-traffic areas.
Versatile Solutions
Promat offers versatile solutions like the Masterboard and Supalux, which can be used in a variety of applications due to their excellent fire resistance and stability. These boards can be specified for use in areas that require both fire protection and a strong, stable building substrate.
When selecting a building board, consider the specific needs of your project—whether that's moisture resistance for a bathroom, fire resistance for a commercial space, or durability for an outdoor facade. Evaluate the size and thickness requirements, as well as any additional properties like acoustic insulation or weather resistance, to choose the most appropriate product.
Benefits of Building Boards or Construction Boards
- Structural Strength – Ideal for load-bearing floors, roof decking, and timber frame walls.
- Versatile Applications – Suitable for dry and wet areas depending on board type (e.g., moisture-resistant or fire-rated).
- Thermal & Acoustic Performance – Certain boards enhance insulation and reduce noise transmission.
- Ease of Installation – Available in manageable sizes, often tongue & groove for tight fitting.
- Fire & Moisture Resistance – Choose specific boards for added safety in kitchens, bathrooms, or commercial builds.
- Cost-Effective – Long-lasting, durable boards that reduce future repair or replacement costs.
Applications of Building Backer Board
- Loft Flooring – Use P5 chipboard panels for strong, walkable attic spaces.
- Roof Decking & Timber Frames – OSB boards provide shear strength and stability.
- Wall Linings & Partitions – Fibre cement and gypsum boards offer fire protection and soundproofing.
- Wet Areas (Kitchens/Bathrooms) – Moisture-resistant boards are perfect for areas exposed to humidity.
- Commercial & Industrial Builds – Fire-rated and heavy-duty boards meet higher safety standards.
- Backing for Tiling or Cladding – Render boards provide a firm, moisture-safe surface for finishes.
