360° Gutter of the Klimahaus

Every year, half a million international visitors to the Klimahaus Bremerhaven learn about the Earth’s various climate zones. How extreme weather conditions can affect a building’s envelope became an unintended issue for the operator of this scientific exhibition center: The salty North Sea air had compromised the functionality of the roof membrane. As a result, water seeped in through the surrounding aluminum-lined gutter and into the insulation, causing damage even in the exhibition halls. The building owner, Bremerhavener Entwicklungsgesellschaft Alter-/Neuer Hafen mbH & Co. KG (BEAN for short), therefore commissioned DADEGO Dachdecker-Genossenschaft Bremen eG to immediately repair the walkable gutter. The requirement was for a weather-resistant product that adheres to the metal substrate and provides long-term protection for the building structure. The building owner, the installer, and liquid polymer manufacturer Triflex consulted on a suitable solution and determined that the fabric-reinforced waterproofing system Triflex ProDetail met the specified requirements.
