Extruded genuine stone paint imitation brick integrated board

Extruded polystyrene board (XPS), also known as extruded polystyrene board, is a new type of exterior wall building material that combines effective insulation, brick like decoration, and long-term weather resistance. It uses high-density extruded polystyrene board as the core insulation layer, composite real stone paint coating and imitation brick grid structure, and is produced into prefabricated products through industrial assembly lines, achieving comprehensive services of "insulation+decoration+waterproofing (mainly based on actual reports)". It is widely used in exterior wall projects such as residential, commercial complexes, and old building renovations, and is an upgraded product that replaces traditional tile and real stone paint construction.

1、 Analysis of Product Core Structure

The product adopts a multi-layer composite structure that balances stability, insulation, and decoration from the inside out, with clear structural hierarchy:

Thermal insulation core material layer: high density extruded polystyrene foam board (XPS) is selected, which is extruded at high temperature and has a dense and uniform closed cell honeycomb structure inside. The core material has a low thermal conductivity (≤ 0.030W/(m · K)), excellent insulation performance (based on actual reports), and can effectively block indoor and outdoor heat transfer; At the same time, it has a relatively low water absorption rate (≤ 0.3%), which can thoroughly avoid the problems of wall moisture regain and insulation layer moisture failure, and is suitable for various environments such as humid and coastal areas.

Enhanced bonding layer: using one-to-one modified polymer adhesive, combined with two-way alkali resistant fiberglass mesh reinforcement treatment. Adhesive has excellent weather resistance and aging resistance, which can firmly bind the core material and the decorative layer, and resist the thermal expansion and contraction stress caused by temperature differences; Grid cloth further enhances the overall crack resistance of the board, avoiding later cracking and delamination of the decorative surface.

Stone like paint facing layer: It is made of high-quality natural growth colored sand as aggregate and stable acrylic lotion. The coating texture is realistic, restoring the rough texture and heavy texture of naturally grown stone, while having strong resistance to dirt and scratches. Dust is not easily attached, and it can be kept clean by rainwater flushing.

Imitation brick dividing layer: Prefabricated imitation brick dividing joints are formed on the surface of the real stone paint coating, meticulously restoring the visual effect of traditional tiling without the need for on-site tiling or jointing. This not only retains the classic texture of imitation brick architecture, but also avoids the hidden dangers of traditional tile peeling and hollowing.

2、 Core product advantages

1. Energy saving effect, stable insulation

The closed cell structure of extruded XPS core material endows the board with good insulation performance. Compared with traditional insulation materials, the heat transfer efficiency is relatively low. It can reduce indoor heat loss in winter and block outdoor heat waves in summer, significantly reducing the energy consumption of building air conditioning and heating, helping the project meet the national exterior wall energy-saving design standards, and the long-term energy consumption cost is relatively low.

2. Imitation brick texture, outstanding appearance value

The combination of real stone paint coating and meticulous imitation brick grid presents excellent visual effects of traditional brick walls and tiling, with rich colors that can be customized (can restore classic imitation brick colors such as red, gray, beige, etc.), suitable for various architectural styles such as European, Chinese, and modern. Compared to traditional ceramic tiles, the panel surface has no color difference, no splicing gaps, and a strong overall feeling. The building facade is clean and atmospheric.

3. Long duration of weather resistance and longevity

The product has strong weather resistance and can adapt to extreme temperature differences of -40 ℃~80 ℃. It is resistant to UV aging, freeze-thaw, and rainwater erosion, and will not fade, powder, or peel off after long-term outdoor use. The real stone paint coating has a high level of stain resistance, which can maintain a clean appearance even after long-term exposure to wind and sun. Its service life can reach more than 25 years, reducing the cost of later renovation and maintenance.

4. Lightweight and safe, easy to construct

Squeezing core material significantly reduces the weight of the board, with a weight per square meter much lower than the combination of traditional tiles and insulation layers. The effect is excellent in reducing the load on building walls and improving the overall safety of the project. The board is prefabricated in the factory, without the need for on-site mixing of real stone paint, tiling, and jointing. It adopts a dual fixing process of "bonding+dry hanging", which greatly improves construction efficiency and shortens the construction period by more than 30%; Simultaneously reducing on-site construction waste and dust pollution, and adapting to projects with strict construction environment requirements such as the renovation of old residential areas.

5. Waterproof (based on actual reports), moisture-proof (based on actual reports), integrated molding

The real stone paint finish is dense and waterproof (based on actual reports), combined with extruded core material with relatively low water absorption rate, forming a complete "waterproof (based on actual reports)+insulation" barrier, which can effectively block rainwater and moisture from entering the wall, prevent wall mold and insulation layer from being affected by moisture attenuation, especially suitable for rainy and coastal high salt spray areas in the south, and improve the overall waterproof performance stability of the building (based on actual reports).

3、 Main application scenarios

Residential building exterior walls: high-rise residential buildings, villas, resettlement houses, etc., balancing insulation and energy-saving with classic brick like decorative effects, enhancing the overall quality of the building.

Commercial public buildings: office buildings, shopping malls, hospitals, schools, hotels, etc., suitable for multi style facade requirements, while meeting the fire prevention (based on actual reports) and long-term requirements of public buildings.

Renovation of old building exterior walls: Renovation projects for old residential areas and old office buildings do not require the demolition of existing walls, but can directly install panels. The speed is suitable for achieving insulation upgrades and new appearance, with minimal construction interference and short construction cycles.

Industrial building exterior walls: factory buildings, warehouses, etc., with weather resistance, pollution resistance, and corrosion resistance characteristics, suitable for the high-performance stability requirements of long-term use in industrial buildings.

4、 Key points for installation and maintenance

Installation method

The process of "grassroots treatment → line marking and grid division → one-to-one adhesive full coating → board pasting and fixing → metal pendant reinforcement → joint sealant treatment" is adopted. First, the board is finely fixed to the wall base layer with adhesive, and then the metal pendant is reinforced to resist wind load. The joints are filled with durable sealant to confirm that the board is installed firmly and sealed tightly.

Maintenance Instructions

Daily maintenance is simple and convenient. Regularly rinse the surface dust of the board with clean water; If there are slight stains in the local area, neutral cleaning agents can be used to wipe and clean. The board is designed with modularity, and partial damage in the later stage can be disassembled and replaced as a single piece without the need for overall renovation. It has low maintenance costs and easy operation.
