Polyurethane Foam Core (PUR) (EN 13165)
Category: F
Density: 35 to 42 kg/m³
Its mechanical strength makes it ideal for structural materials, as it can withstand building loads. It is lightweight, which facilitates panel installation.
Thermal conductivity (λ): 0.021 to 0.023 W/mK
The low thermal conductivity offers superior insulation, minimizing heat loss and enhancing the overall energy efficiency of structures.
Closed-cell structure: 90%
The high proportion of closed cells ensures low moisture absorption and enhanced resistance to corrosion and wear, making it ideal for humid environments or areas exposed to severe weather conditions.
Sound insulation: Due to its density, it also offers good acoustic insulation performance.
Durability: Service life of 30 years
Environmental friendliness: CFC and HCFC free
It does not contain substances hazardous to health and is manufactured using materials that comply with environmental standards.

Connection / fixing options
DETAILS
CLOSE
These boards are not load-bearing or self-supporting structural elements, but fully supported insulation elements. They do not carry loads and cannot resist loads (bending, shear). Although their compressive strength under a uniformly distributed load reaches 150 kN/m², their bending strength does not exceed 15 kN/m².
They are fixed to the load-bearing elements either with adhesive (glue) or with anchors (plastic or metal).
In all cases, at the joint between boards, the use of a sealing material is recommended (typically low-expansion polyurethane foam) to seal the construction.
Applications
DETAILS
CLOSE
They are used for energy upgrades to buildings, contributing substantially to energy savings.
They reduce heat losses and help cut CO₂ emissions, improving the environmental performance of the building envelope.
One of their key applications is floor insulation for cold rooms, where stable thermal performance and high compressive strength are required.
