Pass-throughs are required when installing VILPE roof fans and exhaust ventilation pipes. They prevent water from flowing into openings made in the underlay and the roofing material, thereby ensuring that it remains watertight. Our product selection includes high-quality and easy-to-install pass-throughs for all kinds of roofing materials, colours and pitches. Pass-throughs should be installed with VILPE Underlay 2K Seals to ensure they are 100 % waterproof. The pass-throughs are designed with ease of installation in mind, so these products are suitable for DIY installation conducted by one person without the need for specialist knowledge.
