Against the backdrop of global climate change and increasing resource scarcity, "sustainable development" and "circular economy" have evolved from marginal concepts into core action frameworks across all industries. The construction industry, as a major carbon emitter, faces an urgent need for green transformation. Within this wave of transition, waterproofing materials are undergoing a profound green revolution—shifting from single-function products to full-lifecycle environmental value. Polymer waterproofing membranes represented by TPO and PVC, with their green attributes of recyclability, energy savings, and low VOC emissions, are becoming the technical foundation for low-carbon buildings and green certifications.
Recently, the Ministry of Housing and Urban-Rural Development released the "Guidelines for the Construction of 'Good Houses' (Trial)," which sets out four core standards for high-quality housing construction in the new era: "safety and durability, health and comfort, green and low-carbon, and smart and convenient." Among them, waterproofing, moisture-proofing, leakage prevention, and damp-proofing are key bottom lines related to residential safety and quality. As a leading enterprise deeply rooted in the field of polymer waterproofing, Canlon closely aligns with the comprehensive requirements for "good housing" construction. It actively participates in the compilation of numerous national standards, national standard atlases, authoritative local standard atlases, and national reference atlases.
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, the Hainan Provincial Department of Housing and Urban-Rural Development officially released the "Hainan Provincial Technical Standard for Metal Roofing" (DBJ 46-075-2025). This standard, tailored to Hainan's unique geographical characteristics of high temperature, high humidity, high salinity, high radiation, heavy rainfall, and frequent typhoons, establishes comprehensive technical specifications covering the entire process from material selection, design and construction, quality acceptance to maintenance and repair. It will officially take effect on April 1, 2026. As a participating unit in the standard's drafting, Canlon was deeply involved in the standard's development, providing crucial support for its practicality and implementation through its core products such as polymer waterproof membranes and metal composite panels, as well as its engineering experience.
In the history of modern construction, persistent leakage, akin to a "water curtain cave," has long plagued the industry and end-users. The limitations of traditional waterproofing materials in terms of durability, environmental friendliness, and construction convenience have struggled to meet the higher demands of contemporary buildings for long-term safety, energy efficiency, and sustainability. Today, polymer waterproofing membranes, represented by PVC (Polyvinyl Chloride), TPO (Thermoplastic Polyolefin), and HDPE (High-Density Polyethylene), are leading a technological revolution with their superior performance, becoming the preferred solution for large public buildings, industrial plants, transportation hubs, and green roofs.
Polymer waterproofing membranes play a critical role in modern construction, with Thermoplastic Polyolefins (TPO) and Polyvinyl Chloride (PVC) being two widely used primary materials. Their long-term performance, particularly weatherability and durability, directly determines the reliability and service life of building envelopes. This article will delve into the impact of environmental factors on the molecular structures of these two materials from a materials science perspective and explore the underlying aging mechanisms and their respective application scenarios.
Recently, Shanghai Baoye Group Co., Ltd. released the "Announcement of Bidding Results for Annual Procurement of Waterproofing Materials". Canlon was successfully selected as a winning bidder due to its excellent product quality and professional service capabilities. It will once again join hands with Shanghai Baoye to provide high-quality waterproofing system solutions for its key engineering projects.
In waterproofing solutions for roofs, basements, and municipal engineering projects, polymer waterproof membranes are undoubtedly the mainstream choice today, with TPO and PVC being the two core materials. However, many homeowners, renovation professionals, and even newcomers to the industry easily confuse the two – both are polymer membranes, both can be hot-air welded, and both are high-performance roofing materials, but their actual materials, lifespans, and applicable scenarios are quite different! Today, Canlon will use simple, popular science language, avoiding obscure academic formulas, to help you understand the essential differences between the two types of roll materials and provide practical selection advice for different usage scenarios.
In recent years, China's construction waterproofing industry has witnessed a transformative shift from traditional asphalt-based materials to advanced polymer materials. Three representative polymer waterproofing membranes—PVC (Polyvinyl Chloride), TPO (Thermoplastic Polyolefin), and HDPE (High-Density Polyethylene)—are becoming the preferred solution for modern construction waterproofing due to their exceptional performance. This article provides an in-depth analysis of the characteristics and applications of these three materials and highlights the innovative achievements of industry leader Canlon in the polymer sector.
