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: [Roof Fire Resistance] and [Roof Insulation]. For [Roof Fire Resistance], we solved the issue by sandwiching a non-combustible membrane between the ETFE cushion types. ⇒ World first For [Roof Insulation], 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.

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: fire resistance of the roof and thermal insulation of the roof. The fire resistance was resolved by sandwiching a non-combustible membrane between the ETFE cushions. The thermal insulation 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 technology in all processes of design, manufacturing, and construction. Our company verified and established its performance through membrane analysis programs, experiments on various details, and validation with full-scale mock-ups. Additionally, 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 the fall or drop of ceilings specifically designed for certain 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 ceiling drop prevention measures. 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 are structurally sound will be required for specific ceilings. Similar requirements will also be imposed on existing buildings' specific ceilings during renovations or expansions. This ceiling drop prevention fail-safe net is recognized as a safe structural method for specific ceilings in existing buildings.
