Kamisei Co., Ltd.

Our Cool Spec heatproof Sanshu roofing tiles maintain comfort with a heat-proof coating on the back of tile.

We mainly manufacture Sanshu roofing tiles. We also perform roof construction, install solar panels, and develop and sell roofing materials. We have commercialized Cool Spec heatproof Sanshu roofing tiles. They reduce attic temperatures in summer by means of a heatproof coating on the back of the tile.

  • Business Outline

    Our main line of business is the manufacture of Sanshu ceramic roofing tiles. We have an established reputation in this industry as a manufacturer of high-quality roofing tiles. We are also engaged in roofing construction work, solar panel installation, the development and sale of roofing materials and solar panel materials, and so on. We can make comprehensive proposals as a roof specialist. We are promoting sales of our unique Cool Spec heatproof Sanshu roofing tile technology. Rear coating and low-reflection technology are adopted for this product, unlike conventional reflection-type products. This technology exhibits heat-proofing performance without impairing the surface design.

  • Product Strength

    We particularly recommend our Cool Spec heatproof Sanshu roofing tiles. The heatproof coating on the back of the tiles successfully reduces attic temperatures in summer by as much as 12°C compared with a decorative slate roof. This coating agent was developed in collaboration with Aisin Chemical, which is Japan’s top manufacturer of heatproof coating agents. The basic principle of this heatproof tile was acquired in a demonstration research project for innovation in disaster recovery technology. This was adopted by the Chubu Bureau of Economy, Trade and Industry in FY 2008 and 2009. We are totally committed to developing products for our customers’ needs.

  • Company Strength

    We have a lineup of innovative new products and also the ability to develop products meeting customer requests. We have been engaged in various public-offering type industry-university research and development projects since about 10 years ago. Our partner public organizations for joint research are the National Institute of Advanced Industrial Science and Technology, Aichi Prefecture, and Ibaraki Prefecture. Our partner universities for joint research are the Nagoya Institute of Technology, Toyohashi University of Technology, Meijo University, and Chubu University. We also export our products through trading firms and can take care of the vanning ourselves. With our company’s flexible power we provide the utmost support to our customers.

  • Company Structure

    We have a section in charge of overseas clients in the general affairs department. We are already exporting through trading firms and doing the vanning ourselves, so we have an organization and staff with practical business abilities. In this sense, we have an advantage over other companies in the same trade. The section in charge of overseas clients attends to new clients under the direction of the president. We can meet various requests from clients in Japan and overseas through the trading firms and forwarders we are familiar with.
