Our company, a substrate manufacturer, has recently started handling "louvers"! We can install them on existing substrates or take care of the substrate work for you. Louvers can reduce the hassle of compliance with regulations and strength calculations compared to panel ceilings. They contribute not only to design but also to the lightweight nature of the ceiling and the reduction of a sense of pressure. We also offer seismic power louvers. By applying the "Strong Method" to the substrate, it is possible to further enhance seismic performance. 【Features】 ■ Choose from 10 shapes × films ■ Contributes to lightweight ceilings and reduces a sense of pressure (can be used on walls as well as ceilings) ■ We can introduce cooperating companies for construction ■ Further enhance seismic performance with double construction with the substrate *For more details, please download the PDF or contact us.

"Aerilight" is a non-combustible lightweight ceiling material manufactured by Panasonic, designed for facilities with a focus on lightweight construction, ease of installation, and disaster resilience, making it suitable for seismic reinforcement work. The number of furring strips has been reduced to one-third of that required for seismic ceilings. This eliminates the need for seismic braces in the ceiling framework, reducing the risk of interference with ducts and equipment in the ceiling space. The original brackets pre-installed on the back of the board enable efficient construction. 【Features】 - Significantly lighter than conventional ceiling materials, achieving a mass of 560g per square meter. - Impact upon falling is significantly reduced compared to standard decorative gypsum boards. - Maintains surface rigidity despite being only 4mm thick. - Efficient construction is achieved with original brackets pre-installed on the back of the board. - Being lightweight allows for easy temporary fixing with magnets. *For more details, please refer to the PDF document or feel free to contact us. *"Aerilight" is a product of Panasonic Corporation.
