INSULATION AND ACCESSORIES
Importantly, we never compromise when it comes to the quality of our products. Specifically, our specialized insulation features a high-grade aluminium coating and a built-in vapour barrier. Furthermore, this reflective insulation effectively distributes heat into your room. Consequently, you prevent energy losses into the floor and save on heating costs.Key Benefits for Your Flooring
In addition, our underlay provides essential moisture-barrier protection, which is vital for all concrete sub-floors in Ireland. Because it protects laminates against moisture damage, your floor remains durable for many years. Moreover, the material delivers excellent heat transfer from the underfloor heating system directly to the surface.Installation and Noise Reduction
Specifically, this insulation is also very effective when your project requires floor levelling. Therefore, it creates a perfectly smooth base for your final floor finish. Finally, the unique structure of the material reduces noise significantly, creating a quieter and more comfortable home environment.
Underfloor Heating Insulation Boards
Importantly, choosing the right underfloor heating insulation boards is the most critical step for energy efficiency. Furthermore, high-quality insulation prevents heat from escaping into the ground. Consequently, your rooms warm up faster while your electricity bills stay much lower.

Premium Insulation Details
Specifically, our specialized underlay materials offer a unique blend of protection and performance. Because we use EXPEL + PETM materials, these boards provide the following benefits:
Material properties
- Reflects 90% heat – keeps warmth in the room.
- 100% waterproof – protects against damp.
- Non-toxic – safe for all home environments.
- Fungus resistant – prevents mould growth.
- Impact sound reduction: 18 dB
- Thermal insulation: 0.120 m²K/W
Versatile Usage
In addition, you can use these underfloor heating insulation boards in many different areas. Specifically, they are perfect for:
- Walls and Floors
- Garage doors and Roofs
- Camper vans and Mobile homes
Moreover, you can use them under laminate panels, carpet, or wooden floors. They act as the perfect underlay material for any renovation project.
Insulation Tile Backer Board



Termofol Board Technology
Specifically, our Tile Backer Boards consist of high-density XPS foam with a glass-fibre reinforced coating. Therefore, they are completely resistant to water and humidity. Consequently, these boards are ideal for wet-room areas, bathrooms, and kitchens. Furthermore, they support tiles, mosaic, and natural stone perfectly.
Technical Specification (6 mm)
- Thermal conductivity: λ = 0.033 W/(m·K)
- XPS foam density: 32 kg/m³
- Fire resistance class: E (hardly flammable)
- Compressive strength: ≥ 300 kPa
- Water absorption: < 0.2%
Finally, the XPS TERMOFOL board offers high pressure and crush resistance. Because the core uses closed-cell extruded polystyrene, it provides strong thermal performance. Additionally, the outer polymer mass ensures high impact resistance and easy installation. If you need help choosing, please contact our experts.

Importantly, choosing the right insulation is the most critical step for energy efficiency. Furthermore, high-quality boards prevent heat from escaping into the ground. Consequently, your rooms warm up faster while your electricity bills stay much lower.
Premium Insulation Properties
Specifically, our specialized underlay materials offer a unique blend of protection. Because we use EXPEL + PETM materials, these boards provide amazing benefits. For instance, they reflect 90% of heat and are completely waterproof. Moreover, the material is non-toxic, tear-proof, and highly resistant to fungus or bacteria.
Versatile Usage Applications
In addition, you can use these underfloor heating insulation boards in many different areas. For example, they are perfect for walls, floors, garage doors, and camper vans. Therefore, they act as the perfect underlay material under laminate panels, carpets, or concrete.
Insulation Tile Backer Board
Similarly, our Tile Backer Boards consist of high-density XPS foam with a glass-fibre reinforced coating. Therefore, they are completely resistant to water and humidity. Consequently, these boards are ideal for wet-room areas, bathrooms, and kitchens.
Termofol Board Technology
Furthermore, they support tiles, mosaic, and natural stone perfectly. As a result, they allow quick, easy, and creative construction with reduced drying times. Interestingly, their thermal insulation performance remains completely unaffected by wet conditions.
Technical Specifications
Specifically, the 6 mm thick board offers an excellent thermal conductivity of λ = 0.033 W/(m·K). Additionally, the XPS foam density is precisely 32 kg/m³. Finally, the outer polymer mass ensures high impact resistance and incredibly easy installation for any professional or DIYer.

Furthermore, this reflective layer effectively distributes heat into your room. Consequently, you prevent energy losses into the floor and save on heating costs.
Key Benefits for Your Flooring
In addition, our underlay provides essential moisture-barrier protection, which is vital for all concrete sub-floors in Ireland. Because it guards laminates against moisture damage, your floor remains durable for many years. Moreover, the material delivers excellent heat transfer from the underfloor heating system directly to the surface.
Installation and Noise Reduction
Of course, this insulation is also very effective when your project requires floor levelling. Therefore, it creates a perfectly smooth base for your final floor finish. Ultimately, the unique structure of the material reduces noise significantly, creating a quieter and more comfortable home environment.
