Extruded genuine stone paint integrated board

Extruded polystyrene board (XPS), also known as extruded stone paint integrated board, is a new type of energy-saving building material for exterior walls that integrates insulation, imitation stone decoration, waterproofing (based on actual reports), and weather resistance. It uses high-density extruded polystyrene board as the insulation core material, and is firmly combined with high-quality real stone paint finish through one-to-one composite technology, achieving thoughtful "insulation+decoration" services. It is widely used in exterior wall projects such as residential, commercial buildings, and old building renovations, and is an upgraded solution to replace the traditional "insulation+plastering+real stone paint" construction system.

1、 Core structure and process of the product

The extruded stone paint integrated board adopts a multi-layer composite structure, with progressive layers from the inner to the outer layer, balancing performance stability and decorative performance stability:

Thermal insulation core material layer: excellent extruded polystyrene foam board (XPS) is selected and molded by high temperature and high pressure extrusion, with uniform and dense closed cell honeycomb structure inside. The thermal conductivity of the core material is as low as 0.030W/(m · K), and its insulation performance (based on actual reports) is excellent. It can effectively block indoor and outdoor heat transfer, reduce building air conditioning and heating energy consumption; At the same time, it has a relatively low water absorption rate (≤ 0.3%), which can avoid the deterioration of insulation performance due to moisture, and is suitable for various complex climate 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, avoids cracking and delamination of the later decorative surface, and strengthens the overall stability of the board.

Stone like paint facing layer: It is made of natural growth colored sand and stable acrylic lotion, and is formed by high-pressure spraying and high-temperature curing. 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; The decorative color is rich and highly customizable, supporting various effects such as imitation granite, imitation sandstone, imitation brick pattern, etc., suitable for different architectural styles.

Cover protection layer (optional): Some products will be sprayed with an additional layer of stain resistant topcoat on the surface to form a dense transparent protective layer, further enhancing the weather resistance, stain resistance, and UV resistance of the finish, delaying coating aging and fading, and extending the service life of the board.

2、 Core product advantages

1. Energy saving effect, stable insulation

The closed cell structure of extruded XPS core material endows the board with thermal insulation performance (based on actual reports), which can reduce indoor heat loss in winter and block outdoor heat waves in summer, significantly reducing the building's cooling and heating load and helping the project meet the national exterior wall energy-saving design standards. Long term use can significantly reduce energy consumption and lower building operating costs.

2. Imitation stone texture, strong decorative value

The real stone paint finish effectively restores the texture and texture of naturally grown stone, with rich colors that can be customized. It can create various effects such as imitation granite, imitation sandstone, and imitation brick patterns according to the architectural style, and is suitable for various architectural styles such as European, Chinese, and modern simplicity. Compared to traditional stone, the board is lighter in weight, with less color difference and lower cost. At the same time, it avoids the hidden danger of natural growth stone falling off, making the building facade cleaner and more atmospheric.

3. Long term weather resistance and long service life

The overall weather resistance of the product is strong, and it 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, crack, or peel off after long-term outdoor use. The real stone paint coating is paired with an optional stain resistant topcoat, which has a high stain resistance level and can maintain a clean appearance even after long-term exposure to wind and sun. Its service life can reach more than 25 years, greatly 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 traditional combination of "insulation layer+real stone paint", which effectively reduces the load on building walls and improves the overall safety of the project. The board is prefabricated in the factory, without the need for on-site mixing of real stone paint, plastering and leveling. It adopts a dual fixing process of "bonding+dry hanging", which greatly improves construction efficiency and can shorten the construction period by more than 30% compared to traditional construction; Simultaneously reducing on-site construction waste and dust pollution, especially suitable for 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 failure, especially suitable for rainy and high salt spray areas in the south, and improve the overall waterproof performance of the building (based on actual reports).

3、 Main application scenarios

Residential building exterior walls: High rise residential buildings, villas, resettlement houses and other projects that balance insulation, energy conservation and imitation stone decoration effects to enhance the overall quality and living comfort of the building.

Commercial public buildings: office buildings, shopping malls, hotels, hospitals, schools, etc., suitable for multi style facade requirements, while meeting the fire prevention (based on actual reports), long duration, and safety 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 exterior facade renewal, with minimal construction interference, short construction period, and no impact on residents' normal lives.

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

4、 Installation and Maintenance Instructions

Installation method

Adopting the standardized process of "base treatment → line marking and grid division → one-to-one adhesive coating → board pasting and fixing → metal pendant reinforcement → joint sealant treatment", the board is first finely fixed to the wall base layer through one-to-one adhesive, and then reinforced with metal pendant to withstand strong wind loads. The joints are filled and sealed with weather resistant sealant to confirm that the board is installed firmly and the joints are tight, forming a complete exterior wall system.

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.
