The Helios SDH roof duct seal is a universal solution for vent pipe installations through tiled roofs. Featuring a rolled lead edge, it can be easily shaped to fit various roof profiles. The base plate and cover are made of durable galvanised sheet steel, while the flexible plastic bellows include a stepped connector accommodating duct diameters from 75 mm to 110 mm.
This adaptable design ensures compatibility with almost all common roof tiles, making the SDH an ideal choice for secure, weather-resistant roof penetrations in residential and commercial ventilation systems.
