The R6 Red Cotton Double-Layer Inner Tube enhances duct structural integrity and cleanliness by fully encapsulating insulation cotton with a double-layer aluminum foil polyester inner tube. This design minimizes glass fiber emission into airflow, significantly improving supply air quality while boosting overall duct rigidity and airtightness. Specifically tailored for spaces requiring high indoor air cleanliness and duct quality-such as buildings for sensitive groups (schools, kindergartens, senior apartments) and industrial workshops with cleanliness demands (electronics, pharmaceuticals)-the product is the ideal choice for high-standard central air conditioning systems in office buildings.
The double-layer inner tube forms a more complete and sturdy sealed system, effectively "locking in" fibers to reduce potential impacts on indoor environments and human health, while greatly lowering duct air leakage rates to enhance HVAC system efficiency. The more stable inner tube structure also improves crush resistance and shape retention, making the R6 Red Cotton Double-Layer Inner Tube less prone to damage during installation and use for longer service life. It delivers clear R6 energy efficiency while adding value through cleanliness and durability.
