Tile Backer Boards

Thermal substrate insulation board, also known as tile backer boards or hardy boards, is a specialised, lightweight tile backing designed specifically for wet rooms and bathrooms, offering exceptional resistance to rot and water ingress. These tile backer boards are remarkably lightweight and effortless to cut, requiring only a fine-tooth saw, jigsaw, or utility knife, ensuring ease of handling during installation.

Crafted from a Polyfoam core with polymer-modified cement faces reinforced with glass fibres, this board remains dimensionally stable, impervious to rotting or warping, and provides superior moisture resistance. Its added advantage lies in its significant thermal insulation properties, making it an ideal choice for laying floor tiles, especially over underfloor heating mat systems.

In addition to the boards themselves, we carry a comprehensive range of accessories for installing foam board insulation, including screws, washers, and adhesives. If you require assistance or guidance in selecting the right products, please don't hesitate to contact our friendly team at 01473 559 079. We're here to ensure your project is a success.

Our Range

Each one of our boards covers an area of 0.72m² and can be purchased individually or in 3m² packs, 5m² packs, and 10m² packs offering you further savings. Each of our packs come complete with fixings and joining tape. Our backers boards are available in the following thicknesses:

6mm Boards

6mm tile backer boards are essential materials used in construction and renovation projects, particularly in wet areas such as bathrooms, kitchens, and utility rooms. These boards are specifically designed to provide a stable and waterproof base for tile installation, offering several key benefits to ensure durable and long-lasting tiled surfaces.

Key Features and Uses:

• Waterproofing: One of the primary advantages of 6mm boards is their waterproof nature. They are crafted from materials like cementitious composites or extruded polystyrene foam, which resist moisture penetration. This property makes them ideal for areas prone to water exposure, preventing damage to underlying structures.
• Strength and Durability: Despite their lightweight construction, 6mm backer boards are robust and capable of supporting the weight of tiles and adhesive. They provide a stable surface that helps prevent tile cracking and ensures a secure installation over time.
• Insulation Properties: Depending on the material used, some 6mm backer boards offer additional insulation benefits. This can help improve energy efficiency in buildings by reducing heat loss through floors and walls.
• Easy Installation: These boards are designed for ease of installation, often featuring score-and-snap cutting methods that simplify fitting around corners and obstacles. They can be fixed to walls, floors, and even ceilings using suitable adhesive and mechanical fixings.
• Compatibility: 6mm boards are compatible with various tile types, including ceramic, porcelain, and natural stone. They provide a smooth and level surface for tile adhesion, enhancing the overall finish of tiled installations.

Applications:

They are commonly used for:

• Bathroom Renovations: Creating waterproof bases for showers, tub surrounds, and floors.
• Kitchen Installations: Providing stable surfaces for backsplashes and countertops.
• Flooring Projects: Ensuring strength and moisture resistance in tiled floor installations.
• Outdoor Areas: Protecting against weather exposure in outdoor tile applications.

In summary, they are versatile building materials essential for achieving professional-quality tile installations in both residential and commercial settings. Their waterproofing, strength, and ease of use make them indispensable for any project requiring durable and aesthetically pleasing tiled surfaces.

10mm Boards

10mm tile backer boards are crucial components in construction and renovation projects, particularly in areas that require robust support and enhanced insulation properties. These boards serve as a reliable base for tile installations, offering several key benefits that contribute to the durability and longevity of tiled surfaces.

Key Features and Uses:

• Strength and Stability: One of the primary advantages is their increased thickness, providing greater strength and stability compared to thinner options. This thickness ensures a solid foundation for tiles, reducing the risk of flexing or movement over time.
• Waterproofing: Similar to their thinner counterparts, 10mm backer boards are designed to resist moisture and provide a waterproof barrier. This makes them ideal for wet areas such as bathrooms, kitchens, and utility rooms, protecting underlying structures from water damage.
• Insulation Properties: The increased thickness of 10mm backer boards enhances their insulation capabilities, helping to improve energy efficiency by reducing heat loss through walls and floors. This is particularly beneficial in colder climates or areas where temperature regulation is essential.
• Easy Installation: Despite their thickness, they are engineered for straightforward installation. They can be cut to size using standard tools and secured to walls, floors, or ceilings with adhesive and appropriate fixings, ensuring a snug fit around corners and obstacles.
• Compatibility: They are compatible with a wide range of tile types, including ceramic, porcelain, and natural stone. Their smooth and level surface promotes strong tile adhesion and enhances the overall finish of tiled installations.

Applications:

They are commonly used for:

• Shower and Bath Surrounds: Providing a stable and waterproof base for tiled shower walls and bathtub surrounds.
• Kitchen Backsplashes: Ensuring durability and moisture resistance behind kitchen countertops and stoves.
• Flooring Projects: Supporting tiled floors in both residential and commercial applications.
• Outdoor Installations: Protecting against weather exposure in outdoor tile applications, such as patio floors and walls.

In summary, they offer enhanced strength, stability, and insulation properties compared to thinner alternatives, making them ideal for demanding tile installations. Their ability to withstand moisture and provide a reliable base for various tile types ensures durable and aesthetically pleasing results in any construction or renovation project.

20mm Boards

20mm tile backer boards are robust and heavy-duty materials used in construction and renovation projects where maximum strength, durability, and insulation are required. These boards serve as a solid foundation for tile installations, offering several key benefits that ensure long-lasting and resilient tiled surfaces.

Key Features and Uses:

• Strength and Stability: The primary advantage lies in their substantial thickness, which provides exceptional strength and stability. This makes them suitable for supporting heavy tiles and enduring high-traffic areas without flexing or cracking.
• Waterproofing: Like thinner backer boards, 20mm variants are designed to be waterproof, offering superior moisture resistance. This property is essential for protecting underlying structures from water damage in wet areas such as bathrooms, kitchens, and utility rooms.
• Insulation Properties: The increased thickness of 20mm backer boards enhances their insulation capabilities, contributing to energy efficiency by reducing heat loss through floors and walls. This feature is beneficial in maintaining comfortable indoor temperatures and reducing heating costs.
• Soundproofing: In addition to thermal insulation, they also provide soundproofing benefits, helping to reduce noise transmission between rooms and floors. This is particularly advantageous in multi-storey buildings or areas requiring acoustic control.
• Ease of Installation: Despite their thickness, they are designed for ease of installation. They can be cut to size using standard tools and secured to surfaces with adhesive and suitable fixings, ensuring a precise fit around corners and obstacles.

Applications:

They are commonly used for:

• Commercial Installations: Providing robust support for tiled floors, walls, and ceilings in high-traffic areas such as shopping malls, airports, and public facilities.
• Industrial Settings: Ensuring durability and moisture resistance in factories, warehouses, and production facilities.
• Outdoor Applications: Protecting against weather exposure in outdoor tile installations, including patios, walkways, and swimming pool surrounds.

In summary, they offer unparalleled strength, durability, and insulation properties, making them suitable for demanding construction and renovation projects. Their ability to withstand moisture, provide thermal and acoustic insulation, and support various tile types ensures reliable and long-lasting tiled surfaces in diverse applications.
