What are the pros and cons of PVC vs. TPO?

Roofing materials through the ages have gone through a variety of processes, from ceramic tiles and metal sheets to wood, cement tiles, etc., their role is not only to achieve drainage, protect low-rise buildings from thermal radiation and wear damage, roofing materials are also important for creating a special acoustic environment. Today, within the scope of roofing materials, architects have a lot of room for selection, including a variety of sizes and materials. Each material and size has its own unique properties and characteristics, as they are limited and affected by roof type, project site environment, and maintenance cost budget. Today we introduce what are the advantages and disadvantages of the common PVC and TPO roofing materials.

The advantages and disadvantages of PVC roofing

advantage

1. Strength, toughness and durability: PVC tile has the characteristics of impact resistance, tensile resistance and not easy to crack, so that it can maintain good stability under various climatic conditions.

2. Waterproof performance: PVC tile itself is dense and does not absorb water, there is no microporous water seepage problem, to ensure excellent waterproof performance.

3. Fire performance: PVC tile is a flame retardant material, usually can achieve a higher fire rating (such as V-0), improve the safety of the building.

4. Green environmental protection: PVC tile does not contain asbestos, glass fiber and radioactive elements, can be recycled, in line with environmental protection requirements.

5. High cost performance: The price of PVC tiles is relatively moderate, and the service life is long, and it has a high cost performance.

6. Sound insulation and thermal insulation: PVC tiles also have good performance in sound insulation and thermal insulation, which can reduce indoor noise and energy consumption.

7. Convenient transportation and installation: PVC tile is light in weight, easy to load and unload and install, and improves construction efficiency.

Inferior position

1.Photothermal stability: PVC tile in light and heat stability is poor, outdoor use will appear fading phenomenon, slightly affect the beauty.

2. Chemical resistance: Although PVC tile has a certain corrosion resistance, it may not perform well in some strong acid and alkali environments.

Advantages and disadvantages of TPO roofing materials

advantage

1. Ultra-long weather resistance and service life: TPO waterproof coil has ultra-long aging resistance, and the theoretical service life can reach 50 years, and the proven service life has reached 30 years.

2. Energy saving and environmental protection: TPO coil (especially light-colored series) has excellent sunlight reflectivity, which helps to reduce indoor energy consumption.

3. Excellent low temperature performance: The low temperature flexibility of TPO coil can reach -50℃, meeting the use requirements of extremely cold areas.

4. Color customization service: TPO coil provides a variety of color options to meet personalized customization needs.

5. Chemical corrosion resistance: TPO coil has strong resistance to chemical corrosion such as acid, alkali and salt, and is suitable for a variety of complex environments.

6. Convenient construction: TPO coil can use efficient construction methods such as thermal welding to improve construction efficiency and quality.

Inferior position

1. The price is relatively high: compared with other waterproof materials such as PVC, the price of TPO coil may be slightly higher.

2. Construction technical requirements: The welding construction of TPO coil requires a certain technical level and experience to ensure the welding quality.
