To follow the "movement" of the flooring, no lifting, cracking, or buckling! No need for underlayment or carpentry! An adhesive that is easy to apply, has good disassembly properties, and is user-friendly for workers!

Product Name: IB Bond 【Features】 ✓ Elastic adhesion prevents cracking and lifting ✓ No need for plywood or calking ✓ Easy to apply even in cold weather ✓ Can absorb unevenness with a dedicated notched trowel ✓ Excellent dismantling properties, ideal for floor replacement Unlike conventional adhesives (urethane-based adhesives) that rigidly fix the movement of flooring materials, IB Bond "follows the movement" of the flooring, alleviating the stress that causes warping and lifting. IB Bond is a modified silicone-based adhesive with a solvent-free formulation. There is no solvent odor typically associated with conventional adhesives. It remains soft even in cold weather, allowing for quicker and easier application. * This reduces the burden on workers and can cut dismantling time by about 50% compared to conventional adhesives. * Please refer to the "Dismantling Comparison Video with Conventional Products" on our website.

[Sample Available] Just lay it out; a one-piece unit that doesn't require any adhesive! Equivalent to LL-45 sound insulation and the same thermal insulation as high-performance glass wool insulation 48K!

Product Name: Chardan OY430 [Features] ✔ No need for underlayment; low height of 43mm! ✔ Integrated soundproofing and insulation unit ✔ Easy installation by simply laying it down; installation time approximately 3 hours for 50m² (according to our research) ✔ High impact absorption performance equivalent to tatami mats This is a floor soundproofing material that can be laid under flooring with a thickness of 43mm. Being a bottom layer, it fits well under window frames! Due to its structure filled with special sound-absorbing material, it provides both soundproofing performance and insulation effect simultaneously. OY430 Thermal conductivity: 0.040 [W/(m·K)] OY430HS Thermal conductivity: 0.033 [W/(m·K)] * OY430HS is a high insulation version of OY430. Its composition and basic performance (thickness/soundproofing/constructability/safety) are equivalent to OY430. Using our uniquely designed "OY Joint," we achieved innovative construction that reduces labor and noise during installation. It features high impact absorption similar to tatami mats, ensuring safety during falls. It is also recommended for use in facilities for the elderly and kindergartens.

• Renovation and repair methods

[Sample available!] Just by sticking 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 width of the roofing material! ✓ Reduces indoor and outdoor rain noise by 10dB ✓ Industry’s thinnest! Despite being only 0.55mm thick, it effectively addresses rain noise ✓ Can be applied without hardening even in winter conditions ✓ Easily cut with scissors or a cutter Metal roofs excel in durability, aesthetics, and ease of installation, 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, thereby suppressing the generation of rain noise. The roofs of residences with the tape applied reduce noise not only indoors but also outdoors. Zetoro NV-αII, which reduces rain noise by applying just 30% of the width of the roofing material, can be used in cover methods during new construction or renovation.

From June 2025, measures against heat stroke in the workplace have become mandatory. Additionally, in December 2026, a "Support Package for Heat Wave Measures in Construction Work" was formulated, making heat stroke prevention during the summer a pressing issue, especially for those engaged in the construction industry. This time, we provide a collection of heat stroke prevention materials that can be utilized through Sysmet Co., Ltd.'s comprehensive weather platform, ZEROSAI X-AI. Examples of heat stroke prevention measures possible with ZEROSAI X-AI: - Cloud management of heat stroke information - Forecasting of the heat index (WBGT) tailored to the site with a mesh of 500m for up to 17 days ahead - Observation of the heat index (WBGT) in compliance with JIS standards using a black globe thermometer - Alerts for exceeding work standard values for the heat index (WBGT) via electronic bulletin boards, emails, and business chat tools like direct LINE WORKS We hope this will be useful at your sites as well.

Thank you very much for visiting our company website and catalog, and for your interest in our diesel engine generators. From customer surveys, the most common feedback we received was: - I want to see the actual generators that have been installed. - I want to see them operating under real load. - I want to hear the opinions of companies that have installed them. - I want to see the generators in operation before making a purchase. After all, it’s understandable to feel worried about purchasing a generator without seeing the actual unit first, right? As the saying goes, "Seeing is believing," so we will be holding this tour. It will take place in that area of the Kanto region, where summer temperatures exceed 40°C. We successfully operated our generators this summer as well, so we are confident in handling the heat (sweat). Additionally, it has been confirmed that our generators equipped with the world-leading "Scania engine" are "fuel-efficient." This will surely help reduce daily operating costs. Please note that while we will provide kind and courteous assistance, the meeting and dispersal will be at the site (transportation costs and other expenses will be borne by the customer), so please understand this in advance.

The booth exhibition of Sysmet Co., Ltd. at the 56th Iwasaki Total Solution Fair 2026, held on April 8 (Wednesday) and April 9 (Thursday), has successfully concluded. On the day of the event, members of the technical department involved in meteorological forecasting, equipment development, and fieldwork from our headquarters in Kitakyushu participated to support the booth, which included actual equipment. Many visitors came to the booth, where they asked questions to the meteorologists and inquired about new services such as environmental sensors for noise and vibration, resulting in a great response. On the 8th, we were honored to have the opportunity to give a presentation on "How to View Meteorological Data from a Forecaster's Perspective and an Introduction to AI Wind Forecasting" at the mini stage, led by our meteorologists. Moving forward, we will continue to provide services that contribute to everyone's safety and efficiency, focusing on the theme of "Visible" safety created through the combination of meteorology and technology.
