Anti’con Proof Roofing Underlay 60m²

The Anti’con Proof condensation-protected underlay is a durable roofing underlay developed for Finland’s demanding conditions. This high-quality underlay is entirely manufactured in Finland.

Anti’con Proof underlay is made from a five-layer laminate: The core is made of strong HDPE mesh, providing excellent tensile strength and mechanical durability. A separate waterproof polyethylene film is laminated on the top of the mesh. The bottom of the mesh is laminated with an absorbent fiber fabric that captures moisture condensing on the underside of the underlay. No dripping occurs, and the underside dries quickly when ventilated.

Thanks to its durability, dimensional stability, and waterproof layer, Anti’con Proof can be installed even without sagging. It performs reliably regardless of the chosen roofing material. Anti’con Proof is one of the best underlays in terms of price-to-quality ratio.

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