Huaxian fire smoke exhaust duct solution adopts specially processed ceramic wool, a dedicated fireproof wool for smoke exhaust ducts with superior fire resistance. During installation, secure the fireproof wool to metal ducts with special metal nails, apply fire-resistant glue on all joints, then seal with aluminum foil tape.
1. Simple operation procedures, easy construction.
2. Reduces required building floor height.
3. Low overall cost and low later operation & maintenance cost.
4. Excellent waterpoof performance.
5. Eco-friendly, made from recycled solid waste.
6. Superior fire resistance, Class A1 non-combustible material.
7. Outstanding thermal insulation. It protects ducts and prevents heat transfer and flame spread.
8. Great stability. Ceramic wool is inorganic material with acidity coefficient over 6, much higher than 1.6 of ordinary rock wool. Its stable chemical composition causes no corrosion to metal ducts and metal components, supporting long-term stable operation of smoke exhaust ducts and cutting maintenance expenses.
