The thin plastering system is now the longest application and the widest area of the external wall external insulation system. The external wall insulation and decoration integrated board is the most "young" external wall external insulation system. However, according to studies by industry associations and other institutions, the thin plastering system is gradually being replaced by an integrated system of exterior insulation and decoration panels.
01 System weather resistance comparison
Thin plastering system: The traditional thin plastering system is to apply the paint directly to the exterior wall as a decorative layer. The paint directly contacts the outside and is easily contaminated by stains and dust. Acid and alkali will infiltrate and erode the decorative layer with moisture. Weather resistance and color retention are poor.
External wall insulation and decoration integrated board system: the external wall insulation and decoration integrated board is covered with a special fluorocarbon resin, which will form a dense, hard and tough transparent paint film on the surface of the decorative layer, which prevents moisture, acid, Alkali and stains enter the finish layer, effectively protecting the finish layer. And the F-C bond in the molecular structure of the fluorocarbon resin is the chemical bond with the shortest bond length and the largest bond energy, so its chemical properties are very stable, and it has excellent alkali resistance, weather resistance and corrosion resistance. The surface tension of the fluorocarbon layer is very low, thus giving the surface of the finish layer excellent resistance to staining and self-cleaning.
02 System integrity comparison
Thin plastering system: The traditional thin plastering system must scrape the putty on site during construction. The finish layer and the putty layer are relatively independent, which is prone to delamination, paint film hollowing, peeling, peeling, etc. This is the online hot The "bandage floor" and "bubble floor".
External wall insulation and decoration integrated plate system: the external wall insulation and decoration integrated plate is infiltrated with a special primer. The excellent permeability and adhesion effectively eliminate the isolation layer, significantly improve the strength of the base layer and the binding force of the surface layer, and ensure that the surface layer will never fall off. The introduction of functional groups between each layer of paint film produces a strong chemical bond, ensuring that there is never delamination. Completely eliminate the phenomenon of hollowing, peeling and peeling of the paint film.
03 Comparison of decorative effects
Thin plastering system: The traditional thin plastering system is manually painted or sprayed on site. It is suitable for ordinary paints, real stone paints, texture paints, and colorful paints. The colors are uneven and easy to decorate, and the decorative effect is poor.
External wall insulation and decoration integrated board system: external wall insulation and decoration integrated board factory automated production, suitable for various coatings, real stone paint, texture paint, fluorocarbon paint, metal paint, colorful paint. Especially colorful paint imitation marble paint, thin coating, clear texture, realistic effect, better than natural; and the pattern can be freely adjusted, the surface layer can be made of different colors, various textures and stone texture effects, the degree of imitation of natural marble High, to obtain the same visual effect as marble, and greatly reduce the security risks and installation restrictions caused by marble because it is too heavy. Fluorocarbon paint and metal paint can completely replace aluminum-plastic plate and aluminum plate. The above-mentioned color is even without flower, and the decorative effect is excellent.
04 Anti-cracking comparison
Thin plastering system: The traditional thin plastering system uses plastering mortar and alkali-resistant mesh cloth as the plastering layer. It has poor weather resistance. It is difficult to release thermal stress due to temperature differences and climate changes and it is prone to cracking and cracking. The surface mortar and alkali-resistant mesh cloth are used as the surface layer, which has low impact strength and is easily damaged by external force.
External wall insulation and decoration integrated board system: the external wall insulation and decoration integrated board uses high-density calcium silicate board as the decorative panel, has excellent weather resistance, and the strength is much higher than the surface mortar and alkali-resistant grid cloth, impact resistance, Good resistance to wind pressure. A certain gap will be reserved between the outer wall insulation and decoration integrated board and the board to release thermal stress, which effectively solves the problems of various outer layer cracks and cracks of the thin plastering system.
05 Comparison of system water resistance
Thin plastering: The traditional thin plastering system has low surface waterproof mortar and alkali-resistant mesh cloth, and the thin plastering system is easy to crack, crack and seep, and moisture easily enters the insulation layer, which not only reduces the insulation material Insulation effect and there will be hollow cracking and other phenomena.
External wall thermal insulation and decoration integrated plate system: the external wall thermal insulation and decoration integrated plate is decorated with a special fluorocarbon cover, which has excellent water repellency; the decorative panel is made of high-density calcium silicate board, which is not easy to crack and crack, and has a good waterproof effect. .
06 Construction convenience comparison
In traditional thin plastering systems, paint and insulation materials need to be purchased separately and constructed separately, and the installation process is complicated.
The outer wall insulation and decoration integrated board has achieved multi-functional integration, and the finished product is the finished product. One construction can solve the two functional requirements of heat preservation and decoration, saving time and effort, reducing the dozen or so procedures of the thin plastering system to four, and the entire construction period can be shortened by about half
