Underlayment with UV and alkali stability
This underlay is a high-quality solution for protecting roof structures. With its diffusion-tight and water-repellent properties, it offers robust protection against the elements. The material is specially designed to resist UV radiation and alkaline conditions, ensuring a long lifetime. In addition, the underlay is designed to be trample-proof, contributing to a safe working environment during installation. Its air and vapour tightness ensures that condensation and moisture do not penetrate, effectively protecting your roof. The flexibility of the product allows it to be installed both parallel and perpendicular to the roof pitch and is suitable for trusses up to 1500 mm apart. Make sure the roof pitch is at least 14° for best results.
