Volker Brock, Managing Director of sealant specialist HANNO (Laatzen), is a new member of the board of the German Sealants Industry Association (IVD). Brock wants to do even more to promote the interests of the industry. "We have to look at the building as a whole. What use are all the measures if the joint is not tight and we have to accept heat losses of up to 25 per cent," says Brock, explaining the importance of joint seals. The sealing and insulation specialist HANNO supports fabricators and dealers with its innovative solutions and services and has been committed to sustainable construction for years.
