With the development of science and technology, many new products have appeared more and more rapidly, especially the new products in the decoration industry. Among them, the most popular ones are polyurethane exterior wall insulation and polyurethane exterior wall insulation. Insulation is a technical product for external insulation walls, and the technology used is also very advanced and has many features. For example, it has unique impermeability, light roof load, good heat insulation and thermal insulation performance, significant energy saving effect, convenient construction, fast project progress, and very long service life. However, many friends are still unfamiliar with polyurethane exterior wall insulation, so Next, the editor will tell you about polyurethane exterior wall insulation.
Polyurethane exterior wall insulation manufacturer
Polyurethane exterior wall insulation is a technical product. Technology leadership will reach a new level.

Features of polyurethane exterior wall products
1. Unique impermeability:
Pu hard foam is a microporous foam with a dense structure and a closed cell ratio of up to 92 or above, it has a smooth self-crusting and is an excellent water-impermeable material. Direct spray molding technology is used during construction to make the Pu hard foam layer without joints a complete water-impermeable whole, fundamentally eliminating roof water leakage. Possibility of depth from along the seam. The Pu hard foam layer can be firmly adhered to the base layer, and its bonding strength can exceed the tear strength of the foam itself. Therefore, the Pu hard foam and the base layer are integrated, making delamination less likely to occur and preventing water from penetrating between layers. These characteristics are not possessed by many waterproof membranes, so the waterproof function of Pu hard foam is unique.
2. Good heat insulation and heat preservation performance, and significant energy saving effect.
The thermal conductivity of Pu hard foam is low, and its excellent thermal insulation and thermal insulation effects are unmatched by any other roof insulation material. Pu hard foam is used as a waterproof and insulated roof in general residential buildings. Its thickness is only one-third that of traditional materials, but its thermal resistance is nearly three times that of them.
3. The roof load is light.
Pu hard foam roofing has low density and light weight, so the roof load is light. Part of the load is above the roof support plate. Pu hard foam roofing is one-quarter of the traditional roofing method, which is beneficial to improving the overall structure of the house. It is very important to reduce the project cost, so it is more suitable for large-span, thin-shell roof buildings.
4. Convenient construction and fast progress of the project
Pu hard foam roofing is foamed on-site. The process equipment is simple and easy to operate. It can be sprayed or poured, and can be used on any complex roof. Construction operations are usually carried out by 3-4 people. More than 20 cubic meters can be sprayed every day. Based on a spray coating thickness of 30 mm, more than 700 square meters can be sprayed every day. The work efficiency is ten times higher than that of laying traditional materials. At the same time, it also reduces the labor cost. Reduce labor intensity, improve the working environment, and reduce environmental pollution. The on-site foaming and expansion volume of Pu hard foam liquid raw materials is 15-18 times, so the raw material transportation volume is small. According to statistics, it can reduce vehicle transportation costs by more than 80% compared to using traditional materials, and also greatly reduces the workload of vertical transportation shifts at the construction site.
5. Good engineering quality and long service life.
The excellent impermeability, thermal insulation and lightweight properties of Pu rigid foam lay the foundation for high-quality roofing projects.
After the Pu hard foam spraying is completed, a layer of polymer synthetic coating is sprayed on the Pu hard foam, which not only protects the Pu hard foam, but also acts as a waterproofing. This fundamentally solves the most prominent quality problem of roof penetration in current housing construction. Traditional roof insulation materials easily absorb water and moisture. Conventional waterproofing membranes have a short service life and must be repaired and replaced regularly; while Pu hard The service life of the foam can reach more than 10 years, and the maintenance cost saved during this period is very considerable.
The above is the detailed knowledge about polyurethane exterior wall insulation shared by the editor. We hope that everyone can better understand polyurethane exterior wall insulation through our shared content. Polyurethane exterior wall insulation is becoming more and more recognized in our lives, and the performance of polyurethane exterior wall insulation is also very good. The most representative performance is good heat insulation and thermal insulation performance, significant energy saving effect, and construction is also It is very convenient. In addition, polyurethane exterior wall insulation also has very good environmental performance.
