(Headquarters: Zentsuji City, Kagawa Prefecture; President: Noboru Miyake; "Nanao Industry") and KURARAY KURAFLEX Co., Ltd. (Headquarters: Kita-ku, Osaka; President: Takashi Nakajima; "KURARAY KURAFLEX") today announced the joint development of YUKAPUCT,*1 a floor panel system with excellent soundproofing and shock absorption properties (joint patent pending). Sumisho Tekko Hanbai will handle sales.
The YUKAPUCT system will be on exhibit in the Kuraray booth (AC5341 in the East 6 hall) at the ARCHITECTURE + CONSTRUCTION MATERIALS 2011 to be held at Tokyo Big Sight from March 8 through 11, 2011.
Noise from upstairs rooms is an issue for residents of both detached houses and apartment complexes and is mainly due to discrepancies in residents' schedules; reflecting changing lifestyles. Particularly among those wishing to purchase a two-family house, there is increasing concern about reliable soundproofing with regard to upstairs floors. Furthermore, due to the recent increase in the popularity of wooden floors over carpeting or tatami mats, noise from upstairs has become more noticeable. There is thus a pressing need to develop flooring with superior soundproofing.
In addition, along with the further aging of society, there has been an uptick in reported cases of elderly people accidentally falling at home and breaking bones or becoming unconscious. Wooden floors are slicker and harder than floors that are carpeted or covered with tatami mats and are therefore more likely to lead to physical damage in the event of a fall.
Addressing these issues, Sumisho Tekko Hanbai, which works toward the development of advanced structures for floors, turned to KURARAY KURAFLEX's FELIBENDY,*2 a special nonwoven fabric made through steam jet technology using high-speed steam heating that possesses such properties as shock and sound absorption, long-term durability and heat insulation. A proprietary technology developed by KURARAY KURAFLEX, steam jet technology is seeing an expansion in applications. In planning a multifunctional floor structure, Sumisho Tekko Hanbai looked into combining FELIBENDY with Nanao Industry asphalt vibration-damping and sound-insulation material*3 and suggested that the two companies undertake joint development.
