In the field of building waterproofing, PVC and TPO Himei waterproof tiles have become the “two heroes” in the market with their unique performance.
But facing different building scenes such as industrial plants, photovoltaic power stations, coastal villas, etc., how to choose to balance functionality and economy?
Himei Metal deeply analyzes from multiple dimensions such as fire prevention, waterproofing, anti-corrosion, weather resistance, heat insulation, noise reduction, etc. to help you make decisions.
1. Industrial plant anti-corrosion + fire prevention first
Recommended solution: PVC Himei waterproof tile
Pain point: Pickling workshop and electroplating workshop are highly corrosive, and fire inspection is strict.
Recommended solution: PVC Himei waterproof tile
Reason: The pickling workshop produces corrosive gas during production, which corrodes the underlying steel plate. Himei waterproof tile can customize double-sided anti-corrosion layer to resist acid and alkali erosion. B1 level fireproof carbonizes when exposed to fire, and extinguishes when away from fire to meet fire requirements. Hot air welding is seamless and leak-proof.
2. Photovoltaic roofing: weather resistance + fire prevention first
Recommended solution: PVC Himei waterproof tile
Pain point: The arc of photovoltaic equipment running at high temperature is easy to cause fire, high temperature exposure accelerates aging, and regular maintenance is easy to cause damage and perforation of the roof, leading to water leakage.
Reason: High temperature resistance up to 120℃, anti-ultraviolet whitening rate <5%, with fire protection performance is safer, the entire roof is overlapped by hot welding without water leakage, overlap strength >9N/mm, no risk of water leakage.
Data: The life of the PVC roofing system is 25 years, the same cycle as the photovoltaic module, and the comprehensive cost is reduced by 25%.
3. Coastal buildings: salt spray resistance + UV resistance first
Recommended solution: TPO Himei waterproof tile
Pain point: The climatic conditions in coastal areas are special, with high humidity, high salt content, and strong ultraviolet rays.
Reason: The anti-corrosion layer contains anti-salt spray additives, hot air welding prevents leakage, and adapts to typhoon and rainy climate. The surface TPO membrane has good antioxidant and UV resistance, and is not easily decomposed and aged by ultraviolet rays.
Actual measurement: TPO Himei waterproof tile has no change in salt spray resistance test for more than 3000h, and no change in UV resistance test for more than 10000h.
IV. Renovation of old roofs Construction + performance priority
Recommended solution: TPO Himei waterproof tile
Demand: Convenient construction, better performance than the original roof, solve the problem of water leakage at the joints of skylights and vents.
Reason: TPO Himei waterproof tile is constructed by mechanical fixing + hot air welding, which is highly operable and fast to construct. The entire roof is sealed with TPO coil and tile by hot welding, and there is no water leakage point, which can achieve the effect of water storage without leakage. It also performs well in durability and service life, and will not corrode, perforate, etc. like the original roof.
There is no absolute advantage or disadvantage between PVC and TPO Himei waterproof tile. The key lies in “adapting measures to local conditions”. Only by matching material performance, construction requirements and environmental conditions can the goal of “no roof leakage and long-lived building” be achieved.
