Imitation stone insulation and decoration integrated board

Imitation stone insulation and decoration integrated panel is a prefabricated exterior wall material that integrates the good texture of naturally grown stone with the scale of building insulation and energy-saving functions. It completes the composite of high fidelity stone pattern decorative layer and effective insulation core material in one go in the factory, achieving the triple goal of "decorating like stone, insulation and energy-saving, and efficient installation". This product is an ideal solution to replace dry hanging stone, enhance building quality, and meet energy-saving requirements.

1、 Product Core Structure

The product consists of three main parts: decorative layer, insulation layer, and lining layer, which are formed through high-temperature and high-pressure composite molding. Each layer has clear functions and is firmly bonded.

The high fidelity stone decorative layer (appearance layer) is located on the outermost side of the board, responsible for presenting realistic stone textures. Adopting excellent painting techniques, common types include:

Water in water colorful coating finish: Various colored water-based paint particles are blended through colloid technology, and sprayed in one go to form a point like or flowing effect resembling granite or marble, with high simulation and customizable colors.

Water in sand colorful coating finish: Adding naturally growing colored sand on the basis of water in water, giving the texture a concave convex texture of lychee or burnt surface, closer to rough stone.

True stone paint finish: sprayed with naturally grown colored sand as aggregate, presenting a thick texture like sandstone and slate, with good weather resistance.

Fluorocarbon imitation stone paint finish: Covering the imitation stone layer with fluorocarbon varnish greatly enhances its resistance to ultraviolet radiation, pollution, and self-cleaning ability, extending its service life. The glossiness (matte, semi gloss, high gloss) and surface effect (flat, matte, lychee surface) of the decorative layer can be adjusted as needed.

The insulation core material layer (functional layer) is located in the middle of the board and is responsible for blocking heat transfer. According to the fire prevention level (based on actual reports) and energy-saving standards of the project, the following options can be selected:

Rock wool tape (main product for fire prevention (based on actual reports): non combustible material, high temperature resistance (based on actual reports) exceeding 1000 ℃, all meeting the strictest fire prevention (based on actual reports) requirements for high-rise buildings.

Graphite polystyrene board (SEPS, B1 grade): containing graphite particles, reflecting infrared thermal radiation, with insulation performance improved by about 20-30% compared to ordinary EPS, presenting a silver gray color and good cost-effectiveness.

Extruded polystyrene board (XPS, B1/B2 grade): with good strength and relatively low water absorption, suitable for parts with special requirements for moisture resistance (based on actual reports) and compression resistance.

Polyurethane rigid foam (PU, B1/B2 grade): The thermal conductivity is relatively low among all organic (based on actual reports) insulation materials, with excellent insulation effect, and it adheres firmly to the panel during foaming.

Thermosetting modified polystyrene board (genuine gold board, A2/B1 grade): forms a carbonized layer during combustion, without melting droplets, and has good insulation and fire resistance (based on actual reports).

The lining backboard (reinforcement layer) is composite on the inner side of the insulation layer (against the wall), usually using high-density calcium silicate board, fiber cement board or galvanized aluminum plate. The functions include: significantly improving the bending and impact strength of the board; Balance the stress on both sides to prevent warping and deformation of the board; Provide a flat adhesive base and confirm excellent bonding with the wall.

High strength polyurethane adhesive or epoxy structural adhesive is used between each layer, which is formed by high-temperature and high-pressure composite molding on an automated production line to ensure long-term use without delamination, hollowing, or cracking.

2、 Core advantages

The decorative effect is comparable to that of naturally grown stone, and the cost is greatly reduced: the simulation degree can reach over 90%, and it is difficult to distinguish the authenticity with the naked eye. The comprehensive cost (materials+construction+auxiliary materials) is only 1/3 to 1/2 of that of dry hanging stone, especially suitable for projects with limited budget but pursuing excellent appearance.

Lightweight and high-strength, with good performance: The finished product weight is usually only 8-15kg/㎡, while dry hanging stone (including keel) can reach 50-80kg/㎡. Significantly reducing the load on building structures, adopting adhesive anchor bonding technology, with good resistance to negative wind pressure, fundamentally rejecting the risk of stone falling off from high altitude.

Thermal insulation, energy-saving, and green environmental protection (based on actual reports): The thermal conductivity of the insulation core material is as low as 0.024-0.045 W/(m · K), significantly reducing the energy consumption of building operation. Prefabricated products in the factory, no wet operations on site, reducing dust and construction waste.

Construction effect and shortened construction period: dry operation is adopted, and insulation and decoration processes are completed in one installation. Compared to the traditional method of "first making insulation layer and then hanging stone", it can shorten the construction period of exterior walls by more than 50% and accelerate capital turnover.

Weather resistant and stain resistant, easy to maintain: The decorative layer usually has self-cleaning function, good acidity and alkalinity, UV resistance, and is not easily faded or powdered after long-term exposure to sunlight and rain. Daily rainwater flushing can keep it clean, without the need to regularly apply protective agents like natural growing stone.

No radiation hazards, green and safe: Natural grown stone may contain trace amounts of radioactive substances, while imitation stone veneers use inorganic coatings, all environmentally friendly and without radiation risks.

3、 Applicable scenarios

Excellent residences and villas: Creating elegant and heavy stone facades, significantly enhancing the level and market premium ability of the property.

Commercial and public buildings: hotels, shopping malls, office buildings, sales offices, clubs, schools, hospitals, theaters, etc., achieve the unity of aesthetics and energy efficiency while controlling costs.

Energy saving renovation and exterior wall renovation of old buildings: It can be directly hung or pasted on the original ceramic tiles, coatings or mosaic walls, with minimal construction interference and suitable speed to improve the appearance and energy-saving performance of the building.

High rise and higher rise buildings: Their lightweight characteristics make them particularly suitable for the exterior walls of high-rise buildings, avoiding safety hazards and structural burdens caused by excessive natural growth of stone.

Cold regions with hot summers and cold winters: areas with strict requirements for building energy efficiency, where imitation stone insulation boards can meet both energy-saving indicators and appearance grade requirements.

4、 Installation method description (adhesive anchor bonding process)

Grassroots treatment: Clean up floating dust, oil stains, and loose parts on the wall, and confirm that the wall is basically flat (with a flatness error of no more than 1cm).

Snap line grid: According to the design layout, pop horizontal and vertical control lines on the wall and mark the anchor positions.

Preparation of bonding mortar: Use one-to-one polymer bonding mortar, add water according to the product instructions and mix evenly.

Paste the board: Apply bonding mortar on the back of the board using the strip bonding method or point frame method, and then paste it to the predetermined position on the wall. Use a ruler and rubber hammer to level and compact it.

Mechanical anchoring: Use one-to-one fasteners (such as Z-shaped and C-shaped parts) and expansion bolts to mechanically reinforce the side or back of the board with the wall. Each board usually has no less than 4-6 anchoring points.

Caulking and sealing: polyethylene foam rod (the dimension is about 1/2 of the seam width) is embedded between the board seams, and then weather resistant silicone sealant is injected, and scraped with a scraper to form a concave or flat seam.

Cleaning acceptance: Remove the surface protective film, clean the surface dust and residual adhesive stains with a soft cloth, and check the overall flatness, verticality, and joint quality.

5、 Key points for comparison with traditional solutions (brief explanation)

Compared to dry hanging stone: Imitation stone insulation board does not require keel, is lightweight, has low overall cost, comes with insulation, and has suitable construction speed; Natural growth stone has more stable and superior performance (over 50 years), but it has high cost, long construction period, and the risk of detachment.

Compared to ordinary thin plastering systems, the imitation stone insulation board has a significantly higher grade sense, with visual impact of stone, good stain resistance and crack resistance, avoiding common problems such as cracking, water seepage, and paint fading in thin plastering systems.
