Newsletter now available! Soundproofing technology from luxury cars applied to building materials.

[Sample distribution ongoing!] Unique technology condensed 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 sound insulation and thermal insulation properties. It accommodates a wide range of flooring materials, including solid flooring and SPC flooring, and mitigates impact noise transmitted from upper floors to lower floors. **Features of Shardan** ☆ Integrated sound insulation and thermal insulation unit With a low floor thickness of 40mm, it can secure a space that is "more than 100mm higher than the typical ceiling height." Sound insulation: Industry-first! Achieves floor sound insulation performance of "LL-45" with a thickness of only 40mm, obtaining ΔLL(II)-3S certification. Thermal insulation: Utilizes sound-absorbing insulation material that demonstrates thermal conductivity equivalent to "high-performance glass wool insulation 48K." Workability: Compared to dry double flooring, "construction time is reduced to less than 1/3," allowing for easy installation using specially designed fastening components. Safety: Provides "high impact absorption" equivalent to tatami mats, enhancing 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 base layer. *OY430HS is a high thermal insulation version of OY430.*

[Sample Distribution] Easy installation with sound insulation performance equivalent to LL-45 and insulation performance comparable to high-performance glass wool insulation material 48K! 40mm thick low-floor substrate 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 materials 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 multi-family housing 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 in one package. SPF400 Thermal Conductivity: 0.040 [W/(m·K)] SPF400HS Thermal Conductivity: 0.033 [W/(m·K)] * SPF400HS is a high insulation version of SPF400. Its composition and basic performance (thickness/soundproofing/constructability/safety) are equivalent to SPF400. Using dedicated edge treatment materials and fastening components, we achieve innovative construction that reduces construction time and noise.

【Sample available!】Simply stick it to the underside of a metal roof to 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 are excellent in durability, design, and workability, but their soundproofing performance is insufficient, so vibration-damping tape is used to solve 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 applied vibration-damping tape reduce noise not only indoors but also outdoors. Zetoro NV-αII, which reduces rain noise by applying just 30% of the roofing material's width, can be used in cover methods during new construction or renovation.
