High Density PIR Underfloor Heating Insulation Board Floor Insulation System Solution

Product Overview

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.

Core Advantages

• 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.

Key Performance Parameters

Typical Applications

• 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.
