This is a cushion-type membrane structure that combines ETFE film with a thickness of 500 microns and a non-combustible membrane material. By continuously installing 318 cushion units measuring 3m x 9m, we constructed a membrane roof space of 6,500 square meters. This project had two major themes that needed to be addressed: [fire resistance of the roof] and [thermal insulation of the roof]. For [fire resistance of the roof], we solved the issue by sandwiching a non-combustible membrane between the ETFE cushion types. ⇒ World first For [thermal insulation of the roof], we addressed the issue by creating an air layer in the cushion type and applying special printing to the ETFE. ⇒ World first The combination of ETFE cushions and non-combustible membranes requires very high technology in all processes of design, manufacturing, and construction. *We also have a collection of case studies for other projects.

The membrane structure roof has high light transmittance, is difficult to penetrate ultraviolet rays, and has the property of reflecting heat, making it less likely to accumulate heat. During the hot summer months, metal roofs absorb heat when exposed to sunlight, forcing people to endure the heat underneath the roof, but the membrane structure is different! An experiment comparing the temperature under a metal roof and under a membrane structure at a certain station platform showed that the temperature was 2 to 3 degrees lower under the membrane structure than under the metal roof. I experienced it myself, and even a difference of 2 to 3 degrees felt significantly cooler! For more details, please refer to the catalog or feel free to contact us.

A cushion-type membrane structure that combines ETFE and a non-combustible membrane material of 500 microns. By continuously installing 318 cushion units measuring 3m x 9m, we constructed a membrane roof space of 6,500 square meters. In this project, there were two major themes to address: roof fire resistance and roof insulation. The issue of roof fire resistance was resolved by sandwiching a non-combustible membrane between the ETFE cushions. The roof insulation issue was addressed by creating an air layer in the cushion type and applying special printing to the ETFE. In particular, the combination of ETFE cushions and non-combustible membranes requires very high technical skills in all processes of design, manufacturing, and construction. Our company verified and established its performance through membrane analysis programs, experiments on various details, and full-scale mock-ups. We also developed the air supply system and maintenance plan. *Details of this project are published in the June 25, 2020 issue of Nikkei Architecture. Please take a look.

This is a dedicated net for preventing ceiling detachment and falling, designed for specific ceilings, made from flame-retardant high-strength fiber materials. The design fully complies with the technical standards outlined in the Ministry of Land, Infrastructure, Transport and Tourism's explanatory document regarding measures against ceiling detachment. During the Great East Japan Earthquake, many ceilings fell, causing significant damage. Additionally, ceilings in swimming pools have frequently fallen, resulting in harm. In August 2013, the Ministry of Land, Infrastructure, Transport and Tourism announced Notification No. 771 concerning specific ceilings (suspended ceilings with a height of 6 meters or more, a horizontal projection area of 200 square meters or more, and a unit area mass of 2 kg/square meter or more), which will be enforced from April 2014. As a result, safe structural methods for ceilings that meet structural strength requirements will be mandated for specific ceilings. Similar requirements will also apply to existing buildings' specific ceilings during renovations. This ceiling detachment and falling prevention fail-safe net is recognized as a safe structural method for existing buildings' specific ceilings.
