On a scorching summer day, have you ever felt that city centers are hotter than suburbs? It's not an illusion. Meteorological data shows that urban core temperatures are often 3-5°C higher than surrounding suburbs—this is the well-known "urban heat island effect." One of the key culprits behind this phenomenon is the dark roofs above our heads. Traditional asphalt roofs and black waterproofing membranes can reach surface temperatures of 70-80°C under intense sunlight. Like giant "heat-absorbing panels," they convert solar radiation into heat, continuously baking the city above. The emergence of white TPO cool roofs is changing this situation—it's like applying an "ice pack" to buildings, not only cooling the building itself but also quietly mitigating the heat of the entire city.
Under direct sunlight in summer, the surface temperature of roofs can often soar to over 70°C. This heat continuously flows into the interior through the roof—air conditioners work frantically to cool the rooms, electricity bills skyrocket, and the urban heat island effect intensifies. Worse still, high temperatures accelerate the aging and embrittlement of roofing materials—including rolls and their plasticizers—leading to surface peeling and failure of waterproofing performance. A "feverish" roof not only has a significantly reduced lifespan, but also increases the risk of accidental ignition.
The Anji "Two Mountains" Future Science and Technology City Cultural and Art Center project is located in Anji County, Huzhou City, Zhejiang Province. It is a major project of Zhejiang Province's "Thousand Projects and Trillion Yuan" initiative. The total construction area is approximately 118,000 square meters. The center is divided into six functional areas, including a comprehensive grand theater, a high-end conference center, and a cultural center. It is a comprehensive urban landmark that integrates culture, art, and leisure.
Recently, Canlon has added another internationally authoritative certification – its TPO/PVC waterproof membrane has successfully passed the product rating accreditation of the Cool Roof Rating Council (CRRC) after three years of outdoor testing, making it one of the few domestic companies to hold certifications for both polymer waterproof materials. This also signifies that Canlon's roofing waterproofing products have reached internationally advanced levels in terms of thermal radiation efficiency and green energy-saving performance, opening new channels for expanding into the global green building market.
Compared with traditional distributed photovoltaic service providers, Canlon always adheres to long-termism and is committed to becoming a roof steward for industrial and commercial buildings throughout their life cycle, ensuring that the greatest value is given to customers based on the 25-year life cycle of the photovoltaic power station.
