[Announcement of Product Page Addition] Case Study of Bi-Solate Stage Equipment Floating Floor Installation <Document>

We have added a product page regarding the "Vaisolate Stage Equipment Floating Floor Construction Case" conducted by Tokyo Vitec. This document introduces the Vaisolate floating floor construction case (stage equipment floating floor specifications) through illustrations and photographs. To improve the vibration impact of stage equipment in a theater in Nagoya, the wet floating floor method with Vaisolate specifications was adopted. Since the stage equipment exerts high loads on the center and rotating rail sections, a Celldamper (urethane vibration isolation material) was added to the load-bearing areas. The specifications were selected to achieve a natural frequency of 10Hz with Vaisolate. You can find more details in the related products and catalogs below.

[Announcement of Product Page Addition] Measures Against Subway Vibration in High-End Condominium in Daikanyama [Case Study]

We have added a product page regarding the case study of "Subway Vibration Mitigation for Luxury Condominiums in Daikanyama" conducted by Tokyo Vitec. Due to the proximity of the Tokyu Toyoko Line's underground tunnel to the condominium, there were concerns about the impact of train vibrations. Before construction, we investigated ground vibrations and predicted the vibration and noise environment of the B1 floor living spaces based on that data, planning the installation of vibration-damping materials on the underground exterior walls. To confirm the vibration isolation performance of the vibration-damping material Viburan, we conducted verification measurements for vibration and noise, and found that there was no audible sound from the subway's running solid noise, and no perceptible vibrations, resulting in excellent outcomes. You can find more details from the related products and catalogs below.

A case where vibration and noise measurements were conducted in a preliminary survey to consider the prediction and countermeasures for vibration and noise.

[Notice of Additional Product Page] Vibration Control Measures for Facilities Constructed Above Subway Tunnels (Case Study)

We have added a product page regarding the "vibration control measures for facilities constructed above subway tunnels" conducted by Tokyo Vitec. To consider the prediction and countermeasures for vibration and noise at the planned construction site, where the effects of vibration and noise (solid sound) were taken into account, we conducted preliminary vibration and noise measurements. The vibration insulation effect of the subway by Viblan was excellent, and the noise perceived by hearing was at a very low level, barely noticeable. You can find more details in the related products and catalogs below.

[Notice of Product Page Addition] Vibration Isolation Measures for Wet Floating Floors Using a Combination of Vibra and Other Vibration-Damping Materials <Document>

We have added a product page regarding the materials for "vibration isolation measures for wet floating floors using a combination of Vibra and other vibration isolation materials" conducted by Tokyo Vitec. This document introduces vibration isolation measures for wet floating floors using a combination of Vibra and other vibration isolation materials. One method to display the insulation performance of vibration isolation materials in terms of vibration isolation performance is to evaluate it based on the natural frequency of the vibration isolation material. The natural frequency of the vibration isolation materials we are introducing is approximately 20Hz, which can be considered a good material in terms of vibration performance. You can find more details from the related products and catalogs below.

[Notice of Product Page Addition] Road Traffic Vibration Countermeasure Bibran <Case Study>

We have added a product page regarding the case study of the "Road Traffic Vibration Countermeasure Vibra" conducted by Tokyo Vitec. In an old building facing a road with heavy traffic from large vehicles, a ground vibration survey revealed that the vibration levels increase significantly when large vehicles pass by. In the new building, to block road traffic vibrations, Vibra was installed on the underground exterior walls. To evaluate its performance, vibration measurements were conducted upon the completion of the new building, yielding favorable results. You can find more details in the related products and catalogs below.
