Roof insulation is a crucial step in preserving warmth and reducing heating costs in your home. The roof is the primary source of heat loss, accounting for 30-35% of heat dissipation. Hence, insulating the roof demands special attention.
To achieve effective insulation, it’s important to select the appropriate brand and thickness of polystyrene. The insulation thickness should align with the updated norms of DBN V.2.6-31:2021. According to the new standards, the minimum thermal resistance of combined coverings bordering external air should be R = 7.0 m²·K/W for the I temperature zone and 6.0 m²·K/W for the II temperature zone.
For instance, using Eurobud EPS 100 with a thermal conductivity index of 0.036 W/mK, achieving the minimum thermal resistance as per the current norms for the I temperature zone requires a thickness of 26 cm. Therefore, the insulation thickness for roofing should be no less than 25-35 cm.
In neighboring European countries, the minimum permissible thermal resistance values for roofing are even higher. We are gradually adopting European insulation practices, so it’s anticipated that this standard will continue to rise in Ukraine. Consider this factor now when selecting the insulation thickness!
We recommend using the following brands and thicknesses of EPS polystyrene for roof insulation:
🔹 Sloped roofs: EPS 80 – EPS 120 with a thickness of 25-35 cm
🔹 Roof sandwich panels: EPS 80 – EPS 120 with a thickness of 25-35 cm
🔹 Roof SIP panels: EPS 80 – EPS 120 with a thickness of 25-35 cm
🔹 Flat roofs with moderate load: EPS 100 – EPS 150 with a thickness of 25-35 cm
🔹 Flat roofs with high load: EPS 150 – EPS 250 with a thickness of 25-35 cm
