Glass wool duct micro duct

Duct, insulation, and sound absorption work completed in one process. Lightweight with excellent airtightness. F☆☆☆☆ certification obtained.

The Ministry of Land, Infrastructure, Transport and Tourism's 2019 edition of the "Standard Specifications for Public Building Renovation Works (Mechanical Equipment Construction)" has included glass wool circular ducts (round ducts). The "Micro Duct" is a glass wool duct that excels in sound absorption, thermal insulation, and airtightness. It is available in two types: square ducts and round ducts. We also offer specialized aluminum tape and dedicated processing tools that are heat-resistant, cold-resistant, and durable. Since duct work, sound absorption work, and insulation work can be completed in one process, it is possible to reduce costs and construction time. On-site processing is also possible, making it effective for renovation work. 【Features】 ■ JIS A 4009 (Components for Air Conditioning and Ventilation Equipment Ducts) compliant product ■ Non-combustible material (Certification Number: NM-8569) ■ Listed in the SHASE-S (Society of Heating, Air-Conditioning and Sanitary Engineers of Japan) standard specifications for equipment construction ■ Compliant with the "Glass Wool Box" in the standard specifications for public building construction ■ F☆☆☆☆ certification obtained *For more details, please refer to the materials.
