[Sample Available] A one-piece unit that only needs to be laid out and does not require disposal! Equivalent sound insulation to LL-45 and insulation performance comparable to high-performance glass wool insulation 48K!

Product Name: Chardan OY430 【Features】 ✔ No need for disposal; low height of 43mm! ✔ Integrated soundproofing and insulation unit ✔ Easy installation by simply laying it down; installation time is approximately 3 hours for 50m² (according to our own 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! Since it fills the underfloor space with a special sound-absorbing material, it provides both soundproofing and insulation effects 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. The composition and basic performance (thickness / soundproofing / workability / 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 high safety during falls. It is also recommended for use in facilities for the elderly and kindergartens.

[Sample Presentation] Easy installation with soundproofing performance equivalent to LL-45 and insulation performance comparable to high-performance glass wool insulation 48K! 40mm thick low-floor base material.

Product Name: Chardan SPF400 【Features】 ✔ Low height of 40mm! ✔ Integrated soundproofing and insulation unit ✔ Reduced construction time to less than 1/3 compared to dry double flooring! (In-house research) ✔ Achieved LL-45 with SPC flooring! A multi-type that does not limit the choice of top material This is a floor soundproofing material laid under flooring with a thickness of 40mm. It has been certified for performance with SPC flooring, which is said to be thin and hard, making it difficult to ensure soundproofing performance. With Chardan SPF400, SPC flooring can be used not only in commercial facilities but also in apartment buildings and welfare facilities where soundproofing and insulation functionality is required. Since it is a form that fills the underfloor space with special sound-absorbing material, it provides both soundproofing performance and insulation effect simultaneously. SPF400 Thermal conductivity: 0.040 [W/(m·K)] SPF400HS Thermal conductivity: 0.033 [W/(m·K)] * SPF400HS is a high insulation version of SPF400. The composition and basic performance (thickness/soundproofing/constructability/safety) are equivalent to SPF400. By using dedicated edge treatment materials and fastening components, we achieve innovative construction that reduces construction time and noise.

【Sample Giveaway!】Concentrating unique technology into units, providing overwhelming construction efficiency and a comfortable living space.

Shardan supports comfortable living in collective housing such as condominiums and apartments from the floor up, thanks to its excellent soundproofing and thermal insulation properties. It accommodates a wide range of flooring materials, including solid wood flooring and SPC flooring, and mitigates impact noise transmitted from upper floors to lower floors. **Features of Shardan** ☆ Integrated soundproofing and insulation unit With a low floor thickness of 40mm, it can secure a space that is "more than 100mm higher than the standard ceiling height." Soundproofing: Industry-first! Achieves floor sound insulation performance of "LL-45" with a thickness of only 40mm, obtaining ΔLL(II)-3S. Thermal insulation: Uses sound-absorbing insulation material that demonstrates thermal conductivity equivalent to "high-performance glass wool insulation 48K." Ease of installation: Compared to dry double flooring, it "reduces installation time to less than 1/3," with simple laying using specially designed fastening components. Safety: Provides "high shock absorption" equivalent to tatami mats, improving safety during falls. **Shardan Lineup** ◯ SPF400 / SPF400HS A multi-type that does not limit finishing materials. *SPF400HS is a high thermal insulation version of SPF400.* ◯ OY430 / OY430HS A low-construction type that does not require a subfloor. *OY430HS is a high thermal insulation version of OY430.*

• Double Floor System
