HANNO, the waterproofing specialist from Laatzen, was accepted into the RAL Gütegemeinschaft Fugendichtungskomponenten und Systeme e.V. in September 2016. Under the motto "RAL beats standard", the RAL Quality Association is committed to the highest standards for waterproofing products.

At the beginning of Bau 2017 in Munich, Mr. Bernd Stache, board member of the quality association, handed over to HANNO's managing director Günter Krohn, the award certificate for a RAL quality mark for the first product from the HANNO® building products range.

The fully self-adhesive, patented Hanno®-foil tape DUO Easy 240 has been successfully installed worldwide for more than 4 years and meets the requirements of the quality association.

Further HANNO® products are planned for certification by the quality association.
