● This is a non-combustible material with a fiberglass core and aluminum foil attached to both sides. ● A tape of the same material (such as SS tape) is used at the seams to maintain adhesion. Heat insulation measures for buildings in summer are key. ● In summer, roofs heat up due to solar electromagnetic waves, rising to around 55°C to 70°C. By covering them with SS sheets, radiant heat is reflected, protecting the building from radiant heat that insulation cannot guard against, creating a comfortable space that is less affected by outside temperatures. ● By covering with this product, radiant heat is reflected, protecting the building from radiant heat that insulation cannot guard against, creating a comfortable space that is less affected by outside temperatures. ● The fiberglass reinforced core with double-sided aluminum sheets demonstrates durability, making it less likely to crack from bending and improving workability on site. It also has waterproof performance, achieving moisture-proofing, heat insulation, and airtightness with a single layer of sheet even in fire compartments. ● According to alkali exposure tests conducted at our research institute, when applying this product directly to hardened concrete, no alkali corrosion is observed if primers, adhesives, etc., are used.

- Measures against Wi-Fi signal interference and wireless radio signal interference are supported. - Can be used as a countermeasure against RFID tag interference. - UHF band IC tags are being widely adopted, especially in logistics applications, due to their convenience of being able to read a large number of IC tags over a wide area. However, because their communication range is several meters long, they often read IC tags that are not intended to be recognized. - To prevent misreads, shield curtains, shield roll screens, and shield Roman shades are optimal. - Shield roll screens are a roll screen type that can be retracted and stored when not needed, allowing for accurate reading of IC tags without obstructing the flow of objects or people.

Electromagnetic Wave Shielding Film *Wi-Fi Environment Improvement Measures *Wireless Radio Environment Improvement Measures ● By improving the radio wave environment in windows and indoors, it is possible to bring 5G traffic indoors without causing interference with Wi-Fi 6. Additionally, when applying for a local 5G license, interference adjustments between adjacent local 5G base stations and devices are required based on the radio law-related examination standards. The only solution for the weakest point, window glass, is the electromagnetic wave shielding window film. ● With a visible light transmittance of 70%, it exhibits high transparency while demonstrating excellent heat shielding properties. ● It provides a shielding effect of 25-30 dB, with high transparency and excellent electromagnetic wave (electric field wave) shielding effectiveness, helping to block harmful waves and reduce interference from Wi-Fi 6, 5G, local 5G, etc., thus aiding in countermeasures against speed reduction, delays, and leaks. ● It reflects over 90% of infrared rays (solar heat) contained in sunlight, cuts 99% of ultraviolet rays (UV), and has a high light selectivity with a light efficiency of 1.4 (for 73FG), ensuring low reflection below that of glass without compromising appearance.

- It is a transparent and permeable electromagnetic wave absorber that can create peaks at specific frequencies due to the surface pattern. - In cases where multiple readers are used to read electronic tags, such as in RFID-tagged cardboard forklift operations, placing an absorber partition on the gate side absorbs and shields interference waves from adjacent lanes, enabling normal tag reading and improving errors caused by miscounts. - The partition can be moved as needed, allowing effective zoning of proximity areas and reducing the distance of work movement, leading to labor savings. - Specifications for the transparent electromagnetic wave absorption panel for UHF-RFID in the 920 MHz band: Size: H2,000 x W1,000 x t5.0; Weight: 18.5 kg.

- It is capable of wideband radio wave absorption from 300 MHz to 110 GHz and excels in radio wave absorption performance for oblique incidence. It is easy to cut and process, making installation at the site straightforward. - It is an electromagnetic wave control material and radio wave absorber effective for wireless technology, EMC, and noise countermeasures. - Made primarily from polyolefin-based resin and carbon, it can be produced in suitable thicknesses depending on the applicable frequency. - Wireless LAN access points stored in the ceiling can cause interference due to reflected waves from the deck plate within the ceiling, so the radio wave absorption box cuts off upward radio waves, enhances the directionality of downward waves, and absorbs excess radio waves. - Installing it on adjacent partition walls in the same floor tenant prevents radio wave interference and secures channels. - Near glass windows, it prevents radio wave leakage to the outside and, when used in conjunction with shielding films and floor SS sheets, reduces radio wave interference between floors and inside and outside. - The box for wireless LAN access points, when combined with SS sheets, prevents radio wave interference. - It is used as an electromagnetic wave control material for adjusting wireless LAN access point equipment during system installation (used to isolate and adjust several units at hand).
