Introduction to the Construction Method of Fireproof Insulation Decorative Integrated Panels

The integrated board for external wall insulation and decoration combines the external wall insulation system with the external wall decoration system into one. It can effectively improve the return on investment for users, enhance project quality, reduce energy consumption, and significantly shorten the construction period for external wall insulation and decoration.

The integrated board for external wall insulation and decoration consists of an insulation layer, inorganic resin board, strong composite adhesive, and surface coating, with fire resistance levels fully meeting national fire safety acceptance standards.

Scope of application for the integrated board for external wall insulation and decoration.

The fireproof insulation decoration integrated board is composed of three functional layers: the surface layer (also called the decorative layer), the fireproof carrier layer, and the fireproof insulation layer. The surface decorative layer can be selected from fluorocarbon paint, polyester, latex paint, etc., with over 2800 colors available, allowing for various simulated decorative effects. The carrier layer can be made from inorganic composite boards, aluminum-plastic boards, aluminum plates, etc.; materials can include rock wool, phenolic foam, XPS, EPS, PUR, STP vacuum insulation boards, inorganic insulation mortar, and more.

The fireproof insulation decoration integrated board can be widely applied in various engineering fields such as municipal construction, apartment housing, office buildings, villas, garden attractions, old building renovations, and guard booths. This building material is suitable for new brick-concrete structures, frame structures, steel structures, lightweight houses, and also for energy-saving renovations and indoor and outdoor decorations of existing buildings. The fireproof insulation decoration integrated board is becoming the preferred choice for an increasing number of wall insulation and decoration materials.

The fireproof insulation decoration integrated board can be classified based on its use into outdoor and indoor types; based on the decorative layer, it can be classified into fluorocarbon, polyester, acrylic, etc.; based on the carrier layer, it can be classified into inorganic composite boards, fiber cement boards, aluminum plates, etc.; based on the insulation layer, it can be classified into rock wool, glass foam, inorganic insulation mortar, etc.

Key points for wet application construction of the fireproof insulation decoration integrated board:

1. Treatment of the base wall: All dirt, loose and hollow plaster layers, and oil stains on the wall must be thoroughly removed. Damaged plaster layers must be repaired and leveled. Old walls with moss should be thoroughly cleaned with insecticide. The plastering of new building external walls should meet the specifications.

2. Apply interface mortar: Use a roller or broom to evenly apply or mechanically spray the interface mortar. There should be no missed spots, and the texture should not be too thick.

3. Preparation of polymer bonding sand: The bonding mortar ratio of water to sand is 4.5:1 (by weight). Add water (reference ratio) and mix thoroughly with an electric mixer, let it sit for 5-10 minutes, and mix again before use. The mixed mortar should be used within 2 hours, and it is strictly prohibited to remix already solidified mortar for reuse.

4. Verify dimensions and mark the wall according to the drawings: At the side walls and ceiling, hang vertical lines according to the thickness of the insulation decoration board, and mark the installation control lines for the insulation decoration board on the wall.

5. Paste the integrated board: The area of bonding mortar applied to the back of the board should be ≥40% of the back area. The board with applied bonding mortar should be immediately pressed flat against the base wall and slid into position. During operation, it should be gently and evenly pressed to ensure that the surface flatness of the decorative board meets the requirements, and a 2.0m ruler should be used for flatness correction at any time. After about 24 hours, when the mortar has hardened, install "X" and "I" shaped anchors.

6. Sealant or joint filler: When sealing joints, first fill the seams with insulation material, then use construction weather-resistant sealant or joint filler to seal the joints. The thinnest part of the construction weather-resistant sealant or joint filler should not be less than 3mm thick, and the seal should be filled, dense, continuous, uniform, and free of bubbles.

7. Remove the protective film and clean the surface: After the sealant and joint filler have dried, remove the protective film, clean the board surface, and be careful not to scratch the surface.

8. Acceptance: After removing the protective film and cleaning the surface, check the flatness, verticality, and squareness of the corners of the board. Replace any that do not meet the requirements.

Whether in the severe cold of the north or the scorching heat of the south, the insulation effect of the integrated board for external wall insulation and decoration can meet the national energy-saving mandatory regulations. The materials used have high weather resistance, capable of resisting acid rain and salt spray erosion.

The integrated board for external wall insulation and decoration is suitable for various wall types, including new and old concrete, steel structures, solid brick walls, hollow brick walls, and aerated block walls. It is also suitable for the renovation of old houses. It has excellent outdoor weather resistance, color retention, alkali resistance, water resistance, scrub resistance, crack resistance, temperature change resistance, waterproofing, wear resistance, and impact resistance, with a tough and durable paint film, strong adhesion, and excellent anti-mold effects.
