Many buyers in Southeast Asia have encountered PC sheet yellowing after 1–2 years of use. The transparency decreases, the appearance becomes old, and the structural strength drops. This article analyzes the real causes and solutions. Main causes of yellowing: •No UV protective layer Low-cost sheets use recycled materials and have no co-extruded UV coating. UV rays destroy the molecular structure, causing rapid yellowing and brittleness. •Use of recycled raw materials Recycled PC materials contain impurities and unstable components, which age quickly under sunlight. •Incorrect installation direction Installing the UV-coated side inward makes the sheet directly exposed to sunlight, accelerating aging. •Exposure to chemical corrosion Contact with acidic, alkaline, or oily substances will damage the surface layer and cause discoloration. How to avoid yellowing: •Choose UV co-extruded sheets Ensure the sheet has a UV protective layer of more than 50μm, with a 10-year warranty. •Use 100% virgin raw materials Virgin materials have stable performance and strong anti-aging ability. •Confirm installation direction Strictly install according to the “UV OUT” mark. •Avoid chemical contact Do not use strong corrosive cleaning agents during daily cleaning. How Jietai solves yellowing: All our PC sheets use 100% virgin Bayer raw materials, with 50μm double-sided UV coating, and provide a 10-year anti-yellowing warranty. After years of application in Southeast Asia, the product remains transparent and durable.

Correct installation is critical to the service life, waterproof effect, and appearance of polycarbonate roofing sheets. Many quality problems such as water leakage, cracking, and yellowing are caused by improper installation. This article provides a complete professional guide for Southeast Asian users. Step 1: Confirm the UV side The protective film of the PC sheet is marked with “UV OUT” or “This side out”. This side must face outward to ensure UV resistance. Installing it upside down will cause rapid yellowing and aging. Step 2: Reserve expansion gaps Polycarbonate has a thermal expansion coefficient of 0.065 mm/m/°C. In the high-temperature climate of Southeast Asia, the sheet expands significantly. An expansion gap of 2–3mm per meter must be reserved, and 5–8mm at the ends. Otherwise, the sheet will bulge and crack. Step 3: Drilling requirements The drill hole diameter should be 20%–30% larger than the screw diameter to allow for thermal expansion. Use a sharp drill bit and low speed to avoid chipping. Support the sheet from below during drilling to prevent bending. Step 4: Use special screws and gaskets Stainless steel screws with EPDM waterproof gaskets must be used. Do not use ordinary iron screws or over-tighten, as this will cause stress cracking. Step 5: Fixing with profiles Aluminum alloy or UPVC special profiles should be used for pressing and fixing. Matching rubber sealing strips ensure waterproof performance. Do not directly fix the sheet with angle steel or wood. Step 6: Sealing treatment Use neutral silicone sealant for edge sealing. Do not use acidic, alkaline, or adhesive-containing sealants, which will corrode the sheet surface. Step 7: Protective film handling Keep the protective film during installation to avoid scratches. Remove it within 30 days after completion; long-term exposure will cause glue residue. Step 8: Prohibit stepping on the sheet Do not…

Polycarbonate sheet has become the best substitute for glass in many fields, especially in construction, agriculture, and safety applications. Its comprehensive performance far exceeds that of glass, bringing more value to users. PC sheet is 250 times stronger than glass and 30 times stronger than acrylic. It does not shatter into sharp fragments, making it ideal for family balconies, schools, banks, and public areas where safety is a top priority. In typhoon-prone Southeast Asia, this advantage directly protects life and property. Polycarbonate weighs only half of glass with the same thickness. This greatly reduces transportation costs, labor costs, and the load-bearing pressure of building structures. For large-area roofing and greenhouses, PC sheet is easier to transport and install. High-quality PC sheet is co-extruded with a UV protective layer, which can block 99% of harmful ultraviolet rays. It will not yellow, become brittle, or crack after 10–15 years of outdoor use. Glass has no UV protection function and is prone to thermal expansion and contraction cracking. Hollow polycarbonate sheet has excellent thermal insulation performance, which can reduce heat transfer by 40%–60%. In hot Southeast Asia, it can effectively lower indoor temperature and reduce air conditioning energy consumption. In European cold regions, it reduces heat loss. Multi-wall PC sheet has obvious sound absorption and insulation effects, reducing noise by 20–35dB. It is widely used in highways, residential areas, and airport barriers, which glass cannot match. PC sheet can be cut, drilled, cold-bent, and thermoformed at will. It can be made into curved surfaces and special shapes without breaking. Glass can only be processed in a professional factory and is easy to crack. PC sheet can be used normally in the temperature range of -40°C to 120°C. It is stable in high-temperature summers in the Middle East and cold winters in Europe. Glass…

Solid and hollow polycarbonate sheets are the two most common types, but their performance and application scenarios are quite different. Choosing the right type directly affects project effect and cost. Solid polycarbonate sheet is a single-layer flat panel with high transparency, ultra-high impact resistance, and rigidity. It is almost unbreakable and is mainly used for safety glazing, bank barriers, machine guards, balcony enclosures, and applications requiring high strength. Its advantages are maximum strength, good light transmittance, and thin thickness. Disadvantages are relatively higher price and poor thermal insulation compared to hollow sheets. Hollow polycarbonate sheet has a multi-layer hollow structure, lightweight, good thermal insulation, and low cost. It is the first choice for roofing, canopies, carports, greenhouses, and noise barriers. Its advantages are excellent insulation, lightweight, cost-effective, and suitable for large-area applications. Disadvantages are lower strength than solid sheets and cannot be used for high-security applications. For Southeast Asian users: Budget considerations: hollow sheets are cheaper per square meter, suitable for large-area projects. Solid sheets have better durability and safety, suitable for small-area high-standard applications. In summary, there is no absolute better, only more suitable. Choose according to specific application, load requirements, insulation needs, and budget.

Choosing the right polycarbonate sheet is crucial to the performance, service life, and crop growth effect of a greenhouse. Many buyers make wrong decisions due to lack of professional knowledge, leading to problems such as rapid yellowing, condensation, and poor insulation. This guide will help you make the best choice based on actual needs. First, determine the structure type: twin-wall or triple-wall. For small household greenhouses in Southeast Asia, 6mm–8mm twin-wall PC sheet is sufficient, with low cost and good performance. For commercial large-scale greenhouses or high-cold regions, 10mm triple-wall sheet is recommended for better insulation and strength. Second, anti-fog function is very important. High humidity in Southeast Asia easily causes condensation. Anti-fog PC sheets can prevent water droplets from dripping onto crops, reducing disease and improving yield. If you plant high-value vegetables or flowers, anti-fog sheets are necessary. Third, UV protection is a must. Only PC sheets with co-extruded UV coating can be used outdoors for a long time. Sheets without UV coating will yellow and become brittle within 1–2 years. Be sure to confirm UV protection performance when purchasing. Fourth, light transmittance selection. Clear sheets provide the highest light transmittance, suitable for most crops. Opal diffused sheets make light more uniform and prevent leaf burns, suitable for light-sensitive plants. Fifth, thickness selection. 6mm is the most economical for general greenhouses. 8mm is suitable for areas with heavy rain and wind. 10mm is used for large-span and high-standard greenhouses. In addition, choose reliable manufacturers. Quality differences between raw materials are huge. Virgin material sheets have better performance and longer life than recycled material sheets. By comprehensively considering the above factors, you can choose the most suitable polycarbonate greenhouse sheet to ensure the best investment return.

In recent years, polycarbonate (PC) sheet has become the most widely used building material in Southeast Asia’s construction, agriculture, and decoration industries, gradually replacing traditional glass, acrylic, and plastic films. This trend is not accidental but closely related to the region’s climate, environment, and application needs. First, Southeast Asia has a tropical climate with strong sunlight, high temperatures, heavy rainfall, and frequent typhoons in coastal areas. Polycarbonate sheet’s excellent UV resistance, weatherability, and impact resistance perfectly adapt to this environment. High-quality PC sheets with UV coating do not yellow or crack for 10 years or more, while glass is fragile and acrylic ages quickly. Second, polycarbonate sheet is lightweight, only half the weight of glass, which greatly reduces transportation and installation costs. In Southeast Asia, where labor and logistics costs are increasing, this advantage is very obvious. At the same time, its easy processability allows local construction teams to quickly complete installation without professional equipment. Third, the agricultural development in Southeast Asia is rapid, and the demand for greenhouses is huge. Polycarbonate greenhouse sheets provide good light transmission and thermal insulation, helping increase crop yields and resist bad weather. Anti-fog PC sheets further solve the condensation problem in high-humidity environments. Fourth, polycarbonate sheet has a high cost performance ratio. Although the upfront cost is slightly higher than thin films, its service life is more than 10 years, which is much longer than other materials, reducing the frequency of replacement and overall cost. In addition, the rise of the construction industry, the expansion of residential and commercial buildings, and the improvement of public facilities have further promoted the demand for polycarbonate sheets. With the advantages of safety, durability, and aesthetics, PC sheets will continue to maintain their dominant position in the Southeast Asian market.

For greenhouse growers and agricultural businesses worldwide, choosing the right covering material is critical to maximizing crop yield, reducing energy costs, and ensuring long-term durability. While traditional materials like glass and single-layer plastic have been used for decades, multiwall polycarbonate sheets have emerged as the preferred choice for modern greenhouses. Lightweight, shatterproof, and thermally efficient, they address the key pain points of greenhouse operation—from temperature control to UV protection. In this article, we’ll break down the top reasons why multiwall polycarbonate sheets are the ideal investment for your greenhouse, tailored for buyers and procurement teams seeking reliable, cost-effective agricultural solutions. 1. Superior Thermal Insulation Saves Energy & Stabilizes Temperature One of the biggest challenges in greenhouse management is maintaining a consistent internal temperature, especially in regions with extreme hot or cold weather. Multiwall polycarbonate sheets solve this with their unique internal structure—twin-wall, triple-wall, or honeycomb layers create air pockets that act as natural insulation barriers. Air is a poor conductor of heat, so these pockets reduce heat transfer between the inside and outside of the greenhouse. Compared to single-layer plastic (which offers almost no insulation) and glass (which conducts heat easily), multiwall polycarbonate sheets lower the U-value (a measure of heat loss) to 1.8-2.5 W/(m²·K) (depending on thickness). This means less energy is needed for heating in winter and cooling in summer, cutting your energy bills by 30-40% over time. For commercial growers, this translates to significant cost savings and more stable growing conditions for temperature-sensitive crops like tomatoes, herbs, and flowers. 2. Excellent Light Transmission & UV Protection Crop growth depends on high-quality light, and multiwall polycarbonate sheets deliver exceptional light transmission—80-90%, nearly matching glass. Unlike single-layer plastic, which yellows and becomes brittle over time, multiwall polycarbonate is equipped with a co-extruded UV protective layer (80μm thick) that blocks…
