【SS Sheet: Fireproof Material Certification Number (Non-combustible: NM-1776) F☆☆☆☆ Certification】 ● Reduction of RFID and WiFi signal interference ● Aluminum sheet reinforced with glass cloth ● Both sides are aluminum, providing unprecedented strength, making it less prone to holes or cracks from bending during installation, and excellent in workability. In case of emergencies, the joints and holes can be reinforced with conductive aluminum tape of the same material, enhancing the shielding performance. 【SS Tape】 ● Reinforcement of gaps between shielding materials, repair of holes, reinforcement of metal connections, and around openings (for shielding joints, shielding construction repairs, and joining metal to metal)

- The aluminum tape reinforced with glass cloth uses a high conductivity metal foil as the adhesive surface, providing excellent flexibility, conductivity, and thermal conductivity. - Since it uses a conductive adhesive, it can achieve conductivity in the vertical (thickness) direction just by sticking it on. Being in tape form allows it to be wrapped around cables, devices, and irregular surfaces for use. - By shielding the cables and connectors of electronic devices, it protects them from static electricity and electromagnetic wave interference, enabling measures against electromagnetic wave and radio wave disturbances, as well as static electricity removal. - When installing a freeze prevention device directly onto a resin pipe, aluminum tape treatment on the piping is necessary (wrap this product fully around the piping and ground the aluminum). [Piping treated with aluminum tape can be installed using the same construction data as steel pipes.] - It is used at joints and holes during shielding installation, and the reinforcement improves workability and enhances shielding performance. - It can be used for through-cable treatment.

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.

1) "Wireless LAN Access Point Storage Box" - Controls the direction of radio wave emission to prevent interference, and prevents interference caused by reflections on metal floor surfaces within the ceiling, making it essential for ceiling-mounted access points. - Allows for easy adjustment and relocation of the AP position after installation. - Thickness can be adjusted according to the frequency band used, enabling optimal radio wave absorption. 2) "Heat-Reflective Transparent Electromagnetic Wave Shield Window Film" - Reflects over 90% of infrared rays (solar heat) contained in sunlight and cuts 99% of ultraviolet (UV) rays. - Offers a high light selectivity with a light efficiency of 1.4 (for 73FG), which is unmatched by other companies, demonstrating high heat-reflective properties while remaining transparent. It is a high-performance mirror type that can reflect infrared rays, with a visible light reflectance of less than 10%, preserving appearance, and provides an electromagnetic wave (electric field wave) shielding effect of 25-30 dB. - When used in combination with the adjustment of the installation position of the "Wireless LAN Access Point Storage Box," high attenuation effects are observed in cases of exterior walls: metal curtain walls / structural floors: metal deck plates, etc. 3) In cases where the exterior wall is RC (reinforced concrete) and ALC (autoclaved lightweight concrete), there is no shielding performance, so a composite measure involving the installation of non-combustible aluminum sheets will be implemented.

● The aluminum sheet, reinforced with glass fiber and double-sided aluminum foil, eliminates the need for construction with copper mesh and copper foil, which are susceptible to corrosion. It exhibits unprecedented strength, making it less likely to develop holes during installation or cracks due to bending, unlike conventional products. The joints and holes are reinforced with SS tape of the same material, enhancing workability and providing excellent shielding performance. ● The shielding performance has been proven by numerous electromagnetic wave shielding construction achievements. ● As a durable and easy-to-install shielding material that replaces the difficult-to-handle copper foil in EEG, EMG, and hearing test rooms, the moisture-resistant aluminum sheet shield is easy to maintain, durable, requires no special skills, and is relatively easy to install in interior construction, making it ideal for new builds, renovations, and maintenance work.

● 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.
