High Density PIR Underfloor Heating Insulation Board Floor Insulation System Solution

The High-Density PIR Underfloor Heating Insulation Board is a high-performance substrate specifically developed for modern underfloor heating systems. Utilizing premium Polyisocyanurate (PIR) as the core material, it is manufactured through precision processes into reinforced panels with a density of ≥45kg/m³. It combines exceptional compressive strength with long-lasting thermal insulation performance.

Its unique closed-cell structure not only effectively blocks heat loss to the subfloor, enhancing the thermal efficiency of the heating system, but also provides a solid and level base for the floor finishing, preventing deformation or cracking under long-term load.

• Exceptional Load-Bearing Capacity
  With a high-density structure (≥45kg/m³) and compressive strength (≥300 kPa), it reliably supports the combined load from heating pipes, concrete screed, and floor finishes, ensuring long-term stability without deformation.
• High Energy Efficiency, Minimal Heat Loss
  The ultra-low thermal conductivity (≤0.023 W/(m*K)) effectively blocks downward heat transfer, concentrating thermal energy within the heated space, significantly improving warm-up times and reducing energy consumption.
• Superior Moisture & Dimensional Stability
  High closed-cell content (≥95%) effectively resists moisture ingress, preventing performance degradation due to dampness. Maintains dimensional stability under temperature fluctuations, avoiding floor loosening from expansion/contraction.
• Environmentally Safe & Easy Installation
  Complies with indoor building material environmental standards, odor-free. Lightweight panels are easy to cut, and tongue-and-groove or butt joint designs enable efficient installation, speeding up construction progress.

• Insulation base layer for wet/dry underfloor heating systems in residential and commercial buildings.
• Raised floor insulation requiring high standards of flatness and load-bearing capacity.
• Applications with moisture concerns in low-temperature radiant heating systems (e.g., ground floors, basements).
• Green building projects with high requirements for energy efficiency and living comfort.

• Professional UFH Solution
  Our product formulation and structure are optimized for the specific needs of underfloor heating, providing a complete solution from substrate insulation to load-bearing support.
• Durability for System Longevity
  High density and compressive strength ensure the stability of the floor system over the long term, avoiding repair costs due to base layer failure.
• Comprehensive Heating Efficiency
  Excellent insulation properties can help reduce UFH system energy consumption by up to 30%, shorten pre-heating time, and deliver a more comfortable and economical heating experience.
