High-performance duct that utilizes the properties of paper and aluminum! The CO₂ emissions during production are about one-fourth of those of conventional steel ducts, making it environmentally friendly!
The "Koruair Duct" is an air conditioning and exhaust duct made from recycled paper and aluminum foil. By combining a cardboard surface with excellent insulation properties, with a thickness of 8mm, and a fire-resistant, moisture-proof aluminum foil with a thickness of 20μm, we have achieved a good balance of performance and cost for air conditioning ducts. Additionally, it is about 1/5 the weight of steel ducts while maintaining insulation properties, is easy to process, and the CO₂ emissions during production are about 1/4 compared to traditional steel ducts, making it an environmentally friendly duct. 【Features】 - No insulation work is required, making installation simple and contributing to cost reduction and shorter construction periods. - No burrs are generated, ensuring safe installation. - Excellent design suitability for exposed ducts and PDD methods. - Cardboard is recyclable. *For more details, please refer to the related links or feel free to contact us.
