We have renewed the roof vent pipe! Excellent corrosion resistance, waterproofing, and design! A must-have for rooftop waterproofing: the Damo vent pipe series!
The "Damo Decompression Tube" is a device that discharges humid air pressure to the outside. This product is made of stainless steel SUS304 and has undergone electropolishing, which enhances its corrosion resistance. The stainless steel washer and outer tube firmly secure the waterproof layer at the terminal end. Additionally, it features a design that emphasizes waterproofing, making it aesthetically superior. Changes from the Damo Stainless Decompression Tube Series: ■ Improved Adhesion Performance By applying a sandblasting process to the entire flange area of the main body, excellent adhesion effects are achieved. The round flange part for PVC sheets is coated with PVC on stainless steel plate (SUS304), allowing for thermal welding and integration with the PVC sheet waterproof layer. ■ Enhanced Ventilation Performance Raising the main body flange by 2mm improves ventilation performance, making this product excellent for ventilation. ■ Choose Your Shape We offer two shapes for the main body flange: round and square. Additionally, we provide optional parts and cores compatible with external insulation methods for the round shape designed for PVC sheets. *For more details, please refer to the catalog or feel free to contact us.
