How do Onduline sheets perform in terms of insulation?
Onduline sheets offer good thermal properties, making them suitable for various climate conditions. Here are the key performance metrics:
- Thermal Conductivity (λ):
- According to the NF X 10-021 standard and L.N.E Test report DMAT/1707916, the thermal conductivity of Onduline sheets is 0.099 W/m·°C. - Thermal Insulation Tests by SIRIM QAS INTERNATIONAL SDN BHD:
- Thermal Conductivity: 0.03 W/m·K.
- Resistance of Heat Transmission (R Value): 0.19 m²·K/W.
- Thermal Transmittance (U Value): 5.32 W/m²·K. Test method: ISO 8990:1994.
While Onduline sheets demonstrate good thermal protection, it's important to note that they are not comparable to dedicated insulation materials like stone wool, EPS, XPS, or PIR. Onduline sheets are primarily roofing materials. However, they do offer superior thermal performance when compared to other roofing products.
