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.
Available Options
Available coatings and colours
Simple Polyester
Nominal coating thickness: 25 μm ± 5 μm
It is the most widely used and cost-effective coating option for metal facings. It is suitable for both exterior and interior surfaces and is typically used in building applications in inland areas under normal environmental conditions, i.e. non-corrosive atmospheres with low levels of air pollution. It provides adequate protection for outdoor exposure conditions (RC3) and long-term aesthetic performance.
Durable PVC Plastisol
Nominal coating thickness: 200 μm
It stands out for its exceptional durability and is ideal for demanding environments. It offers high wear resistance and long-term colour retention, even after prolonged exposure to UV radiation and adverse weather conditions. It provides adequate protection for outdoor exposure conditions (RC5) and long-term aesthetic performance.
High Hygiene PVC
Nominal coating thickness: 120 μm
It is classified as a food-safe coating, offering excellent antibacterial protection. It is suitable for indoor applications requiring high hygiene standards, making it ideal for surfaces that may come into contact with food.
High Performance PVDF
Nominal coating thickness: 50 μm
It is ideal for high-specification architectural projects where aesthetics are of primary importance. It offers high wear resistance and long-term colour retention, even after prolonged exposure to UV radiation and adverse weather conditions. It provides adequate protection for outdoor exposure conditions (RC4) and long-term aesthetic performance.

Fixing / fastening options
They are fixed to the supporting structure using the standard method of visible fixing.
Designed for roofs with a minimum slope of 10%.
Fixings are recommended at the crowns rather than in the valleys.
End-lapping (overlap) is not recommended.
However, if required by project specifications, the overlap length must be from 350 mm to 450 mm and must match the profile pitch.
The panels are supplied without overlap. The removal of the inner facing section and the polyurethane (PUR) foam core is carried out on site.
The panel joint design, combined with sealing materials, helps achieve:
- Minimisation of thermal bridges
- Prevention of air and moisture ingress
- Reduced installation time
- Limited need for additional accessories
