Our Construction Materials Business is diversified: processing, sales and installation of heat-insulating glass wool for houses; processing and installation of high heat-insulating pair glass for high-rise buildings, etc.; processing and assembly of sash glass for houses; installation of architectural film; interior finish work for large-sized buildings; and design, manufacture and installation of aseismic ceilings.
With regard to the glass installation for high-rise buildings, we have installed the pair glass in the Chubu Centrair International Airport and Tokai Campus of the Nihon Fukushi University. Also, we delivered residential sash glass to major house manufacturers and construction companies. Our quick delivery and fine service taking advantage of our distribution network are highly evaluated by the customers.
In recent years, we have further expanded the business into interior work for large buildings, providing outstanding interior spaces which employ aseismic ceilings with decorative ceiling materials and the plasterboard molding unit "PRZO" for emphasizing the effect of indirect lighting.

Interior work / large building ceiling construction

Interior work

  • Decorative ceiling construction with plaster board molding unit "PRZO"
  • The plaster board molding unit "PRZO" enables us to create various kinds of interiors that can bring about beautiful and functional indoor spaces, including those allowing indirect lighting to be used extensively, providing soundproofing and acoustic effects (for movie theaters, etc.), or enabling energy saving and office automation.

Seismic ceiling construction

  • Construction of earthquake-resistant ceilings
  • A new earthquake-proof glass-wool ceiling made by ATS method has been installed in 105 facilities nationwide. The facilities that have adopted it include the general gymnasiums, schools, and other public facilities, where it is highly regarded for reliable quality and excellent construction technique.

ATS method makeup glass wool new antiseismic system ceiling

To protect irreplaceable lives from earthquakes

■Features of ATS construction method
[1] With the light and soft glass wool veneer used on the ceiling board, the ceiling members are very light (3.6 kg/㎡ or less).
[2] The new ATS-based antiseismic system ceiling enables the ATS main bar to prevent the ceiling board from rising.
[3] The ATS crossbar also has a wide H-shape on the back side, and the main bar back is engaged with the cross bar back and directly fixed with screws, so it is overwhelmingly stronger than conventional fixing methods using angle plate, etc.
[4] In addition, as the ATS crossbar is fixed with screws with the ceiling board uplift prevention frame at the center of the grid, falling of the crossbar can be prevented, and the surface rigidity of the grid has been dramatically increased. It is a new type of antiseismic system ceiling.
■Features of “Luxalon® 300C Swim” antiseismic system ceiling
[1] Despite being made of metal, this ceiling weighs as little as 5.4 kg/㎡.
[2] The ceiling is excellent in heat and noise insulation.
[3] The rigid stringer structure does not allow ceiling members to come off.
[4] The colored aluminum provides excellent appearance, allowing for other applications than swimming pools.
