Integrating waterproofing and improving housing cannot be separated from policy guidance , but also requires independent exploration and innovation by enterprises.
Recently, the Jiangsu Provincial Department of Housing and Urban-Rural Development released the second batch of new technologies for key promotion and application in improved housing. Starting from waterproof materials, water supply and drainage, renewable energy, prefabricated decoration, and all-age friendliness, a batch of new technologies and processes were announced to promote the construction of safe, comfortable, green and smart improved housing.
The document prioritizes the promotion of waterproofing materials and new technologies for underground and roofing projects, including polymer-modified asphalt waterproofing membranes, synthetic polymer waterproofing membranes, reactive polymer waterproofing coatings, and hot-melt rubberized asphalt waterproofing coatings. Waterproofing materials suitable for interior, roofing, and exterior wall projects can include polymer emulsion waterproofing coatings and cement-based waterproofing materials, and detailed requirements are outlined.
What new technologies and new requirements does the document propose?
·Photovoltaic building integrated system
The document states:
Regarding renewable energy, improved housing can adopt photovoltaic building integrated systems (BIPV). PV modules are used as building materials or components, such as photovoltaic non-transparent curtain walls (roofs) and photovoltaic tiles. These systems are designed, constructed, and inspected simultaneously with the building, and are coordinated with the building's style and functionality. The systems adopt a "self-generation, self-use, and local consumption" model.
As the cornerstone of distributed photovoltaics, the quality of the roof directly determines the service life of the entire distributed photovoltaic roof system. Canlon has focused on researching and achieving breakthroughs in the technical direction of building photovoltaic integration based on the design and application of polymer waterproof membranes. Currently, traditional roofing solutions on the market, whether metal roofs, color-coated steel tiles, or cement roofs, cannot achieve a 25-year lifespan. Canlon's polymer products, represented by TPO, PVC, TMP, and PMP, meet the ultra-long durability requirements of exposed roofing scenarios and fully match the 25-year service life of photovoltaics, allowing roofing to move from traditional to integrated.
·Performance and life of coils and coatings
The document states:
Waterproofing materials suitable for underground and roofing projects include polymer-modified asphalt waterproofing membranes, synthetic polymer waterproofing membranes, reactive polymer waterproofing coatings, and hot-melt rubberized asphalt waterproofing coatings. Waterproofing materials suitable for interior, roofing, and exterior wall projects include polymer emulsion waterproofing coatings and cement-based waterproofing materials, with detailed requirements. For example, polymer emulsion waterproofing coatings for exposed surfaces must meet the following requirements: artificial climate accelerated aging requirements: cumulative radiation energy ≥5040 kJ/m²·nm (approximately 2745 hours), exhibit no cracking, delamination, blistering, adhesion, or holes, maintain a tensile strength retention rate ≥80%, and maintain a flammability rating of no less than B2.
Take the quick-drying, solvent-free, anti-sagging polyurethane waterproof coating (MPU-Pro) independently developed by Canlon as an example. As an environmentally friendly coating, it produces no VOCs during the entire production, construction, and waterproof use period; as a single-component product, the construction operation is convenient and construction can be carried out by opening the cover; the product has a wide construction surface and can be sprayed or scraped on flat or vertical surfaces; the pure white product color avoids the addition of carcinogens such as tar (black) or liquid coumarone resin, and is easier to distinguish than other color products; the film-forming time is fast, and as a polyurethane coating that does not contain organic solvents, the film-forming time is comparable to that of solvent-based single-component polyurethane, truly achieving both health and efficiency, and becoming the most reliable "invisible base color" for building "good houses".
Conclusion: Technology brings happiness to human life
From "sheltering from wind and rain" to "long-term reliability", from "single function" to "system coordination", Jiangsu Province's new technology policy for improved housing not only sets a new "quality standard" for the coatings industry, but also outlines a development blueprint of "high performance, long life, and greenness".
With "green, low-carbon, intelligent, and safe" as our core values, Canlon, from the perspective and original aspirations of the building materials industry, is committed to becoming the "invisible guardian" of the era of improved housing. We hope that our new products can empower buildings to continuously evolve and usher in a beautiful future of happy human habitation.
