Elevate the efficiency and comfort of your underfloor heating system with Tekwarm UFH Gridboard PIR. This cutting-edge solution features lightweight PIR insulation for superior thermal properties, coupled with a laminated grided layer designed for accurate underfloor heating pipe placement.

We also have a EPS Gridboard available. 

Key Features

  • Superior Thermal Insulation: With a Lambda (λ) value of 0.022 W/mK, the PIR gridboard offers exceptional thermal insulation, reducing energy costs and improving the efficiency of underfloor heating systems.
  • Enhanced Fire Safety: Achieves Euroclass F fire performance, contributing to the overall safety of your property.
  • Precision Pipe Placement: The grided polypropylene laminated layer ensures accurate placement of underfloor heating pipes, enhancing the system's effectiveness.
  • Strong Compressive Strength: Offers compressive strengths of 120 kPa for thicknesses under 50mm and 140 kPa for thicknesses between 50-100mm, ensuring durability under floor loads.
  • Eco-Friendly Material: Manufactured from CFC and HCFC-free PIR, featuring a low ozone depletion potential (ODP) and zero global warming potential (GWP), making it an environmentally responsible choice.
  • Easy Installation: Square edges and a lapped detail for defined joint sealing simplify installation, making it suitable for both professional and DIY projects.
  • Versatile Application: Ideal for new builds and retrofit installations alike, its adaptability makes it suitable for a wide range of property types and project scopes.
  • Long-Lasting Durability: Designed to last for the life of the building without any loss in thermal performance and resistant to rot, mould, and fungi.
  • Seamless Integration: Can be installed over concrete slabs or other substrates with a suitable Damp Proof Membrane (DPM), providing flexibility in application.
  • Optimised for Water-based Systems: Specifically designed for water underfloor heating systems, ensuring that your heating setup operates at peak efficiency.

Why use a gridboard for underfloor heating?

Gridboards optimise underfloor heating by ensuring precise pipe placement for even heat distribution. The PIR insulation specifically helps direct heat upwards, enhancing room comfort efficiently.

Is PIR gridboard suitable for water or electric underfloor heating systems?

PIR gridboard is tailored for water-based underfloor heating systems, given its excellent thermal insulation and pipe retention capabilities.

Can screed be applied directly over the gridboard?

Yes, screed can be directly applied over Tekwarm UFH Gridboard PIR, making it a solid substrate for flowing screed applications due to its structure and sealing features.

What thickness is recommended for my project?

Thickness selection depends on insulation requirements and space. Thinner boards (25mm) are used for less elevation, while thicker boards (up to 100mm) provide higher insulation values.

What advantages does the laminated gridded layer offer?

The laminated gridded layer aids in systematic pipe placement and enhances pipe clip retention, ensuring uniform heat distribution and secure pipe positioning.

Can Tekwarm Gridboard be used for retrofitting existing floors?

Absolutely, it's suitable for retrofit projects, offering an efficient way to enhance underfloor heating insulation with minimal disruption.

How durable is Tekwarm Gridboard?

Tekwarm Gridboard is designed for longevity, resistant to rot, mould, and fungi, maintaining its thermal performance for the building's life.

Is the PIR insulation environmentally friendly?

Yes, Tekwarm's PIR insulation is sustainable, with zero GWP, low ODP, and 100% recyclability.

When should I choose PIR gridboard, and when should I choose EPS gridboard?

Opt for PIR gridboard for higher thermal performance requirements and when minimal installation height is crucial. Choose EPS gridboard for more budget-sensitive projects where a balance between cost and insulation performance is needed.
