Sauerland Spanplatte, with an experience of more than six decades, is exporting to 90 countries, and has been an active supplier to the Asian door industry since 2008. The company introduced the eco-friendly timber infill. In 2018, over 8 lakh doors were made in India alone using the tubular boards technology. Unfortunately, door construction in Asian countries is yet to involve as the conventional door sets being produced provide protection against outsiders, but external sound still penetrates through. This is of great concern, especially to homeowners living in high-rise apartments and townships, where privacy is greatly desired, and needs to be addressed by builders and architects.
Sauerland has scaled the technology for the Asian door industry and introduced fire protection cum acoustic doors with cores in several configurations and options with up to 44 dBs sound reduction. Sauerland cores when used in a main door provide sound reduction of 34dB and act as a fire containment, without using any inorganic material like Gypsum board, Cement board, Calcium Silicate or Fiberglass, to achieve the 60 minutes fire rating as per BS 476: Part 22: 1987 or as per IS 3614 Part 2 (1992). The door-sets are provided with perimeter seals and drop seals for achieving insulation against external noise.
Since Sauerland cores have a very low formaldehyde level of E1, they are safe for internal use in residential buildings. In fact, door manufacturers in Asia can now offer builders and architects a triple acting door-set, which is sound-proof, and provides fire protection of 60 minutes along with smoke containment technology.
