The Secondary disaster occurred frequently during the earthquake with Smokeproof hanging wall
In commercial buildings and office buildings etc. exceeding a certain size, installation of fire prevention equipment called "smokeproof wall" is mandatory. It is a partition hanging 50cm from the ceiling to prevent diffusion of smoke and toxic gas in the event of a fire and most of them were made of glass to maintain aesthetic looks. However, during the 2007 Chuetsu-coast earthquake and the 2011 East Japan Great earthquake, the glass fell and scattered over people, equipment, fixtures and products and caused many secondary disasters. As a result, the need for highly transparent and resin-made incombustible sheets that can maintain aesthetic appeal with an emphasis on safety has increased.
High transparency born by fusion of glass fiber and polyvinyl chloride
We have developed a non-flammable and highly transparent sheet by using 100% glass fiber as the base fabric and transparent special resin polyvinyl chloride as the resin and created fusion effect with these proprietary technology of the Wavelock Group.
While maintaining the characteristics of the resin, it achieves high light transmittance of 90% and transparency. By using this as a smokeproof wall, it became possible to increase the safety at the time of the disaster while maintaining aesthetic appearance.
In addition, it is easier to transport and install due to its lightness of about 1/10 of the glass, and so we expect demand will increase related to this product.
Wavelock Group's “high transparency incombustible sheet”
Wavelock Group's high transparency incombustible sheet is a proprietary product characterized by incombustibility, lightweight, no breaking, and no scattering. Since it is lightweight, there is no need for reinforcement work of the ceiling upon installment and it is easy to adjust space layout changes as well as the time of new construction. We expect a wide range of demand to increase. In addition, we have acquired certification of non-combustible material from the Ministry of Land and Transportation and it can be used as a partition for special buildings subject to interior restrictions.
