Introduction

DAIKEN Corporation, based in Osaka, Japan, has taken a significant step in the acoustic market by launching two innovative soundproofing insulation products. On June 23, they introduced 'Insulation Sound Absorbent Wool R' for walls and ceilings, along with 'Insulation Sound Absorbent Wool B' for flooring applications. These products are designed to meet both insulation and sound absorption needs, ensuring that soundproof rooms can be constructed without compromising on space. As energy efficiency standards become more stringent, DAIKEN aims to enhance its proposal capabilities in the soundproofing sector by utilizing these advanced materials.

Background

Since 1982, DAIKEN has specialized in the development and sale of construction acoustic products, including sound-absorbing ceilings and soundproof doors. With a focus on residential applications, they excel in crafting soundproof rooms suitable for various purposes like home theaters, musical instrument practice, and remote work. Traditionally, adding soundproofing materials required additional space for insulation wool used in walls and flooring, often leading to increased wall thickness and a reduction in livable area. With the recent revision of the Energy Conservation Law, effective from April 2025, new buildings must meet energy-saving standards, increasing the demand for high-performance insulation solutions in residential spaces.

Such legislative changes make it increasingly necessary to utilize insulation that also provides excellent sound absorption without increasing the thickness of walls or floors, which this new product line aims to address. 'Insulation Sound Absorbent Wool R' and 'B' combine dual functionalities, allowing for a spacious design while maintaining top-notch acoustic capabilities.

Product Features

1. Insulation and Sound Absorption Combined

These new insulation products are engineered to provide high insulation performance without compromising sound absorption. By integrating both functionalities, there’s no need for separate installations of insulation and sound-absorbing materials. This streamlined approach not only preserves the livable dimensions of the space but also reduces construction time.

The sound absorption effectiveness of both products matches or exceeds that of DAIKEN's currently available 'Sound Absorbent Wool', ensuring top performance.

2. Certification for Fire-Resistant Structures

The 'Insulation Sound Absorbent Wool' products have obtained individual certification from the Ministry of Land, Infrastructure, Transport, and Tourism for a range of structural and facade combinations. This certification permits their use in various residential designs that require fire-resistant criteria, broadening their applicability across different geographical regions.

3. Compliance with Energy-Saving Regulations

Both 'Insulation Sound Absorbent Wool R' and 'B' meet the thermal resistance values necessary for compliance with energy-saving standards set by the Ministry of Land, Infrastructure, Transport, and Tourism. Specifically, the thermal resistance values are 2.7㎡・K/W for 'R' and 2.4㎡・K/W for 'B'. This compliance supports the growing demand for energy-efficient residential constructions.
