Vibration-damping soundproof tape: The soundproofing mechanism of Zetoro NV-αII.

[Sample available now!] Make walls thinner. Easy installation by simply sticking and sandwiching it with gypsum board for noise reduction! Lightweight, reducing the burden on workers.

Iida's unique vibration-damping soundproofing technology, which does not rely on traditional "thick and heavy" soundproofing methods, creates a quiet and comfortable living space. Easily tackle noise issues with simple installation by just sticking and sandwiching it onto gypsum boards! Its lightweight nature also helps reduce the burden on workers. Iida Sangyo's vibration-damping material, 'Zetro NV-αII', is a 0.5mm thick wall vibration-damping tape that "converts vibrations into heat to block sound." By simply sticking it between double layers of gypsum board, the TLD-45 wall is upgraded to TLD-50. It improves the coincidence phenomenon around 2kHz by 5dB. [Features] - Easy installation by just sticking and sandwiching onto gypsum boards - Adhesive tape eliminates the need for glue - Reduces installation time by approximately 70% compared to our standard - Lightweight, reducing the burden on workers *For more details, please refer to the PDF document or feel free to contact us.

[Sample available!] By simply applying it to the underside of a metal roof, you can reduce rain noise. With about 30% coverage relative to the roof width, the effect is outstanding!

Product Name: Zetoro NV-αII 【Features】 ✓ Just apply 30% of the roof material width! ✓ Reduces indoor and outdoor rain noise by 10dB ✓ Industry’s thinnest! Despite being only 0.55mm thick, it effectively mitigates rain noise ✓ Can be applied without hardening even in winter conditions ✓ Easy to cut with scissors or a cutter Metal roofs excel in durability, design, and workability, but their soundproofing performance is insufficient. The vibration-damping tape solves rain noise issues. The vibration-damping tape applied to the metal roof converts the vibrational energy from falling raindrops into thermal energy, suppressing the generation of rain noise. The roofs of residences with the vibration-damping tape reduce noise not only indoors but also outdoors. Zetoro NV-αII, which reduces rain noise by applying just 30% of the roof material width, can be used in cover construction during new builds or renovations.

[Sample Giveaway!] Just 0.5mm. Simply sandwich it between drywall to enhance the soundproofing performance of your walls.

【Features】 ■ With a thickness of 0.5mm, it does not require significant design changes. ■ Improves the coincidence phenomenon around 2kHz by 5dB. ■ Lighter than soundproof sheets, reducing work burden. ■ Can reduce installation time by 70% compared to soundproof sheets. The wall vibration control tape utilizes Iida's unique "vibration control soundproofing technology" that does not rely on thickness or weight. It is mainly adopted in multi-family housing. For more details, please check the Iida Industry website at the link below. You can request and confirm the following items on the website: - Sample requests are welcome. Please feel free to contact us. - A series of installation videos showing how to apply it to gypsum boards. - The mechanism of vibration control soundproofing and soundproofing performance regarding partition walls. - Auditory confirmation of the effects on partition walls.

【Sample available!】Just stick it on Galvalume steel sheets. The industry's thinnest at 0.55mm for roof noise reduction.

**Features** - The industry's thinnest!! A tape with a thickness of 0.55mm solves rain noise issues. - Reduces indoor and outdoor rain noise by 10dB. - Only needs to be applied to 30% of the roof material's width. - Stays flexible and adheres well even in winter conditions. - Easy to cut with scissors or a cutter. For more details, please check the link to the Iida Sangyo website below. You can request and confirm the following items on the website: - Sample requests are welcome. Please feel free to contact us. - View videos measuring rain noise at a rainfall rate of 100mm/h. - View installation videos. - Free download of technical materials (effects when applying drainage hardware, performance comparison with insulation boards, durability, etc.). Past adoption examples: - Insulation boards became unusable when stored outdoors due to rain. With this product, indoor storage is possible without taking up much space. - Soundproof sheets were too heavy and difficult to install, so I wanted something easier to work with. - Now I can propose a combination of Galvalume roofs with vibration-damping tape to clients concerned about rain noise.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

Last month, we held a spring safety conference hosted by our company. We have compiled the details and atmosphere of the day into a PDF. We would appreciate it if you could take a moment to read it.
