About HANNO
Hanno Werk GmbH & Co. KG is a manufacturer of products for sealing, insulating and damping in construction and industry. The product portfolio comprises impregnated joint sealing tapes and multifunctional tapes (Hannoband), foil tapes for joints and building connections, seals made of PE foam, cellular rubber and EPDM, as well as systems for airborne sound, thermal and structure-borne sound insulation based on PU foams, melamine resin foam, heavy layers (PEVA) and nonwovens. In addition, PU filter foams for air and moisture filtration as well as composite and impregnated foams for cargo protection are produced. The company processes polyurethane, polyethylene and melamine resin foams, EPDM, chloroprene and MS polymer sealants. Application consulting and planning of sealing connections according to the 3-level model complement the offering; for this purpose, HANNO publishes practical guides such as the "Little Assembly Helper" for the installation of windows and exterior doors. The company is based in Hanover-Laatz
