Tekwarm Foiled 400 KPA UFH Board

Introducing the Advanced Tekwarm Foiled 400 KPA UFH Board for Precision Underfloor Heating

The Tekwarm Foiled 400 KPA UFH Board sets a new standard for underfloor heating installation. Crafted from lightweight, 400 KPA grade Expanded Polystyrene (EPS), and featuring a unique TFF (Top Foil Faced) finish, this board is designed for fast, accurate, and efficient underfloor heating pipe installation. The foil overlay remains flat across the board, ensuring the grooves remain unobstructed for pipe placement. This innovative solution is suitable for 12mm diameter underfloor heating pipes, with routing at 150mm centres and radius returns as standard.

Key Features:

  • High Precision and Efficiency: Pre-routed channels ensure accurate pipe installation, enhancing the system's overall thermal performance.
  • Top Foil Faced Finish: The TFF finish boosts thermal reflection, contributing to a more efficient heating system.
  • Eco-Friendly Construction: Manufactured from CFC and HCFC free EPS, aligning with environmental sustainability goals.
  • Versatile Application: Ideal for both new builds and retrofit installations, with a design that lasts the life of the building without thermal performance degradation.

Installation & Application

Tekwarm Foiled 400 KPA UFH Boards facilitate speedy installation over solid ground floors or other substrates in fully supported applications, with a Damp Proof Membrane (DPM) as necessary. The board's design and materials ensure ease of use while maximizing the efficiency of underfloor heating systems.

Environmental Commitment

Reflecting a strong commitment to environmental sustainability, Tekwarm Foiled 400 KPA UFH Boards boast a Global Warming Potential (GWP) of zero and a low Ozone Depletion Potential (ODP), making them a responsible choice for eco-conscious projects.

Benefits of Using Tekwarm Routed Insulation Boards for Underfloor Heating

Routed insulation boards are specialized panels designed for use in underfloor heating systems, featuring pre-cut channels for the easy installation of heating pipes or cables. Their design and material composition offer several benefits for both the efficiency of the heating system and the installation process. Below are the benefits of using routed insulation boards in underfloor heating systems, followed by guidance on their appropriate usage and finishing the floor after installation.

  1. Improved Thermal Efficiency: Routed insulation boards are made from materials with high thermal resistance, which significantly reduces heat loss downwards. This ensures that more heat is directed upwards into the room, improving the efficiency of the underfloor heating system and potentially lowering energy costs.

  2. Easy and Quick Pipe Installation: The pre-cut channels in the insulation boards are designed to precisely fit heating pipes or cables, making the installation process quicker and easier. This reduces the risk of installation errors and saves time for professionals and DIY installers alike.

  3. Enhanced Structural Integrity: These boards provide a solid base for the heating system, supporting the weight of the floor finish and the foot traffic above. This can help in preventing cracks or damage to the heating elements and the floor covering.

  4. Uniform Heat Distribution: The arrangement of the pipes or cables in the pre-cut channels helps in achieving a uniform distribution of heat across the floor surface, eliminating cold spots and ensuring a comfortable indoor environment.

  5. Versatility: Routed insulation boards can be used with various types of underfloor heating systems (water-based or electric) and are compatible with many types of floor finishes, offering flexibility in design and use.

  6. Noise Reduction: These boards can also offer acoustic benefits by dampening sounds, contributing to a quieter indoor environment, which is particularly beneficial in multi-story buildings.

When to Use Routed Insulation Boards

Routed insulation boards should be considered in the following scenarios:

  • New Construction or Major Renovations: When accessibility to the subfloor is not an issue, and there's an opportunity to optimise energy efficiency from the outset.
  • Rooms with High Heat Loss: Such as basements or rooms with large windows, where additional insulation can significantly improve thermal efficiency.
  • When Uniform Heating is a Priority: In spaces where eliminating cold spots is essential for comfort and energy efficiency.

Finishing the Floor After Installing Underfloor Heating

After the underfloor heating system has been installed with routed insulation boards, the finishing process typically involves the following steps:

  1. Secure the Heating Elements: Ensure that heating pipes or cables are securely fixed within the routed channels to prevent movement during the floor finishing process.

  2. Conduct a System Test: Before laying the final floor covering, it's crucial to test the heating system to ensure it operates correctly.

  3. Apply a Levelling Compound (if necessary): For certain types of floor finishes, applying a self-levelling compound or screed over the insulation boards and heating elements creates a smooth, level surface.

  4. Install the Floor Finish: Depending on the chosen material (tiles, laminate, wood, etc.), the floor finish is then laid on top of the insulation boards. It's important to select a floor finish that is compatible with underfloor heating, ensuring it can withstand the heat output and allow efficient heat transfer.

  5. Final System Check: Once the floor finish is installed, perform another test of the heating system to ensure everything functions as expected after the complete installation.
