Anti’con Rankka Roofing Underlay 60m²

The Anti’con Rankka condensation-protected underlay is the original high-quality condensation underlay for tile and metal roofs. This premium underlay was developed in Finland in the 1980s specifically for demanding Finnish conditions. It is one of the most well-known underlays on the market and is entirely manufactured in Finland.

The Anti’con Rankka underlay consists of a five-layer laminate: the core is made of strong HDPE mesh, providing excellent tensile strength and superior mechanical durability. A separate waterproof polyethylene film with added friction surface is laminated on the top of the mesh to improve work safety. The underside of the mesh has a highly absorbent fiber layer with suction pockets that can capture condensation forming on the underside of the underlay under all conditions. No dripping occurs, and the underside dries quickly when ventilated.

Due to its durability, dimensional stability, and sealing film, Anti’con Rankka can be installed even without sagging. Anti’con Rankka is considered the “king” of roofing underlays.

Made from polypropylene (PP) fabric + polyethylene (PE). The material is recyclable.
