Precautions for using Q-type rock wool insulation and decorative integrated panels

When using the Q-type rock wool thermal insulation and decorative integrated board (usually referred to as the rock wool thermal insulation and decorative integrated board), you need to focus on material selection, construction environment, construction technology, finished product protection and later maintenance. The following are specific precautions:

1. Material selection

Rock wool requirements: Hydrophobic rock wool should be used, that is, a hydrophobic agent should be added to the rock wool to achieve the water absorption rate required for the exterior wall thermal insulation and decorative integrated board, and to avoid the water-absorbing expansion of rock wool, which will cause hollowing and deformation of the thermal insulation and decorative integrated board, affecting its service life.

Material quality: When purchasing, you should choose a reputable manufacturer to ensure that the density, thickness and fire resistance of rock wool meet standards. Generally, the density of rock wool should be between 80-120kg/m³ to optimize thermal insulation performance.

Preparation of auxiliary materials: Various auxiliary materials, such as adhesives, anchors, caulking agents, etc., should also be prepared in advance to avoid construction delays due to material shortages.

2. Construction environment

Temperature requirements: The ambient temperature during construction should not be lower than 5°C. Anti-freezing measures must be taken for the adhesive during winter construction. When the temperature exceeds a certain range, such as 200°C, appropriate external protection and insulation measures must be taken to keep the thickness and bulk density of the rock wool board unchanged.

Humidity requirements: In a humid environment, a moisture-proof agent should be applied to the base layer to prevent the rock wool from absorbing moisture and affecting the thermal insulation performance.

Weather conditions: Construction should be carried out under dry, windless or wind conditions not exceeding Level 5. Rainproof measures should be taken during rainy season construction.

3. Construction technology

Base treatment: Clean the wall surface to remove oil stains, floating ash and loose layers to ensure the surface is smooth, dry and free of open water. The basic plastering layer should be non-foaming and sand-free, and the plastering quality should reach the 1:3 cement mortar mark.

Board cutting: Cut the length and width of the integrated board according to the wall size to ensure accurate dimensions. When cutting the rock wool thermal insulation decorative integrated board, the required length should be cut strictly according to the length direction of the integrated board, and the required width should be cut according to the width direction of the integrated board.

Panel installation:

When pasting the integrated board, apply adhesive on the wall and stick the integrated board on the wall to ensure that it is firmly and flatly adhered. The flatness and verticality of the pasting should meet the requirements. After each piece is pasted, the extruded mortar should be removed in time.

When installing anchors, insert the processed anchors into the reserved holes of the integrated board and tap lightly with a hammer to fix them to the wall. The effective anchoring depth of anchors into the concrete base layer should be ≥ 25mm, and the effective anchoring depth into the masonry wall base layer should be ≥ 50mm.

The panels should be installed from bottom to top, from left to right, using staggered seams to improve the overall stability and effect. The gap between each board should generally not exceed 5mm. Excessive gaps will cause a thermal bridge effect, thereby reducing the thermal insulation effect.

Seam treatment: Apply sealant to the gaps between the integrated panels to ensure that the gaps are tight and prevent water seepage. Seams need to be sealed with silicone glue to prevent thermal bridging.

4. Finished product protection

Protection measures: During the construction process, attention should be paid to protecting the installed integrated panels to avoid collisions and scratches.

Safety measures: Pay attention to safety during construction and wear protective equipment such as safety helmets and gloves.

5. Later maintenance

Regular inspection: The surface of the board should be checked regularly to see if there are cracks, peeling, etc.

Cleaning and maintenance: Wipe the surface of the integrated board regularly with a damp cloth or neutral detergent to keep it clean and beautiful.

Maintenance and replacement: If the sealant is found to be peeling off or cracking, it should be repaired and replaced in time.
