Advantages of fireproof performance of PVC waterproofing membrane in practical application
1. Reduce fire risk
Applicable to flammable environments (such as warehouses, wooden structure roofs), reducing the risk of igniting the roof due to external fire sources (welding sparks, cigarette butts, etc.).
In high-temperature equipment areas (such as around factory chimneys), the flame retardancy of PVC membranes can prevent heat radiation from causing fires.
2. Extend escape and rescue time
When a fire occurs, the self-extinguishing property of PVC membranes can slow down the burning speed of the roof, buying valuable time for personnel evacuation and fire fighting, which is especially important for crowded places (shopping malls, gymnasiums).
3. Pass fire inspection
In projects with strict fire protection requirements (high-rise buildings, hospitals, schools), B1 flame-retardant PVC membranes can directly meet the acceptance standards and avoid rectification costs caused by non-compliance with material flame retardancy.
4. Reduce secondary hazards
Compared with traditional asphalt-based waterproofing materials, PVC has no melting droplets when burning (avoiding ignition of other items), and the smoke toxicity is low (but still need to pay attention to HCl gas hazards).
5. Enhance safety in coordination with fireproof structures
It can be used in combination with fireproof isolation belts, fire-resistant insulation layers, etc. to improve the overall fireproof performance of the building, especially suitable for steel structure roofs (fireproof and waterproof integration requirements).
