In modern architecture, the choice of roofing materials is crucial, not only related to the waterproof performance of the building, but also affecting the overall life and maintenance costs of the building.
In recent years, TPO (thermoplastic polyolefin) materials have become a popular choice among roofing materials due to their superior waterproof properties and environmentally friendly properties. However, when faced with the two different application methods of Himei waterproof tiles and TPO full-adhesive roofing, many people have questions when choosing.
This article will delve into the comparative advantages of Himei waterproof tiles and TPO full-adhesive roofs to help you make a more informed choice.
Structural strength and stability
Himei waterproof tiles are roof tiles that combine TPO membranes and steel plates. They adopt a composite structure, which significantly enhances the overall strength and stability of the roof. Steel plates not only provide strong support, but also better resist wind, snow and other external loads, ensuring that the roof remains stable and durable under various extreme weather conditions.
In contrast, although TPO fully bonded roofs have excellent waterproof performance, they are not as good as composite steel plate roof tiles in terms of structural strength and stability. Especially when facing large external loads, the durability of TPO fully bonded roofs may be compromised. What is lacking.
Construction speed and convenience
Himei waterproof tiles are constructed using mechanical fixing + hot air welding. The construction method is the same as that of a single-layer metal roof. The long edge overlap is welded by an automatic welding machine and local nodes are welded manually. It has strong operability and fast construction.
TPO fully bonded roofs are constructed using full bonding + hot air welding. During construction, special adhesives need to be applied to the metal plates and coils. The adhesive must be completely dry before proceeding to the next step of construction. The waiting time is long and it is difficult to fully adhere the coils. Larger, it is easy to cause wrinkles or local hollowing, and the construction speed is slow. The requirements for the base layer are higher. The base layer needs to be smooth, clean and have sufficient adhesion, otherwise the bonding effect and waterproof performance will be affected. And during the construction process, weather conditions (such as temperature, humidity, etc.) will affect the bonding effect, which may lead to fluctuations in construction progress and quality.
Durability and service life
Himei waterproof tiles also perform well in terms of durability and service life. The steel structure effectively prevents damage to the waterproof layer caused by movement or deformation of the base material, significantly extending the service life of the roof.
The durability of TPO fully bonded roofs depends in part on the stability of the substrate. Over time, the rock wool substrate may develop problems such as deformation and cracking, which will affect the waterproof performance and overall durability of the TPO membrane.
Fire performance
Safety is one of the important considerations in roofing material selection. Himei waterproof tiles usually have better fire resistance because the steel plate material itself has good fire resistance. Experiments have proven that Himei waterproof tiles can extinguish fire immediately, but TPO will cause flame spread, and the fire prevention effect is lower than Himei waterproof tiles.
Maintenance and repair
In terms of maintenance and repair, the advantages of Himei waterproof tiles are also very obvious. Due to the protective effect of steel plates, the need for roof maintenance is greatly reduced, reducing long-term maintenance costs.
When problems arise with TPO fully-adhesive roofs, it is more difficult to find leaks and repair them. The repair cost is higher and the effect may not be as good as the initial construction.
economic cost
Himei waterproof tiles have significant advantages in terms of cost: their installation process is simple and fast, reducing construction time and labor costs; maintenance requirements are low and easy to repair, and long-term maintenance costs are low.
In contrast, TPO full-adhesive roofing has higher economic costs due to complex installation requirements.
To sum up, Himei waterproof tiles have significant advantages over TPO fully bonded roofs in terms of structural strength, ease of construction, durability, fire resistance, maintenance and cost. For construction projects that pursue high strength, long life and low maintenance requirements, Himei waterproof tiles are undoubtedly the more ideal choice.
In practical applications, choosing suitable roofing materials can not only improve the overall performance of the building, but also effectively reduce long-term use and maintenance costs. Therefore, before making a choice, it is recommended to fully evaluate the advantages and disadvantages of different materials based on specific building needs and environmental conditions to ensure the optimal roofing solution is selected.
