Product Information
The Superfoil SF19 Plus boasts impressive tensile properties, with a length of 606/580N/50mm and width of 514/526N/50mm. This ensures the material can withstand significant stress without tearing or losing its shape. Furthermore, it offers excellent resistance to water penetration (W1) and has a water vapour resistance of 1200MNs/g. This makes it an ideal choice for areas that are prone to moisture or dampness. The product also has a resistance to tearing, with a length of 275N and width of 305N, ensuring it remains intact and functional even under challenging conditions.
This insulation material also has a high thermal resistance, with a 1.63 R value. This means it is highly effective at preventing heat transfer, helping to keep your space warm in the winter and cool in the summer. The Superfoil SF19 Plus also has a fire rating of Class E (behind plasterboard), adding an extra layer of safety to your building project.
