Construction Process of External Wall Rock Wool Insulation Board

The exterior wall rock wool insulation board is a special rock wool board for exterior wall insulation, using A1 grade non-flammable fireproof and heat insulation material, with the advantages of high compressive and tensile strength, low water absorption and moisture absorption, good dimensional stability, will not produce thermal expansion or contraction and anti-aging, etc., The rock wool board can be compatible with external wall systems, provide buildings with effective thermal insulation, energy conservation, fire protection, and extreme weather protection.

The exterior wall rock wool insulation board is designed and produced specifically for the external insulation and thin plastering system of the building. It is suitable for the exterior wall insulation or energy-saving renovation of newly built or existing buildings where the foundation strength is concrete or brick walls and other dense structures. . As a kind of building material, rock wool insulation board has attracted more and more attention. Rock wool insulation boards have excellent fire protection, thermal insulation, and sound-absorbing properties. Therefore, many people choose to use them in home insulation projects.
 Construction process

1. The basic wall shall meet the requirements of the Code for the Acceptance of Construction Quality of Concrete Structures (GB 50204--2002), Code for the Acceptance of Masonry Construction Quality (GB 50203-2002), and the requirements for the quality acceptance standards of the corresponding primary wall. Before construction, the related department shall confirm the acceptance of the structure. If the deviation of the base wall is too large, the mortar should be leveled.

2. The installation of the control steel vertical line for each corner of the house is completed. In the case of high-rise buildings and super-tall buildings, steel vertical lines are qualified by theodolite inspection.

3, the outer wall of the balcony railings, rain tube brackets, plug-in fire ladders and other installation is completed, and should take into account the effect of insulation system thickness.

4. The auxiliary frame of the outer window is installed.

5, Wall scaffold holes, wall holes and wall defects use the appropriate material to repair.

6. The removal of the reinforcing heads and projections of the concrete beams or walls is completed.

7. The deformation joints of the main structure should be handled in advance

8. According to the project quantity, construction site and construction time requirements to formulate the construction plan, the sample should be preceded by a model to determine the fixed consumption, Party A, Party B and the material supplier negotiate and determine the material consumption. The person in charge of construction before thermal insulation construction should be familiar with the drawings.

9. Organize the construction team to conduct technical training and conduct a good safety education.

10. Material should be designated by the responsible person. The mixing ratio, mixing equipment and operation should meet the requirements. It should be strictly prepared according to the manufacturer's instructions. It is forbidden to use outdated slurry and mortar.

11. According to need, prepare a mixing station and a warehouse for stacking materials. The erection of the mixing station needs to select the direction of the leeward, close to the vertical transportation machinery, the mixing shed needs to be closed on three sides, and one side is used as the access channel. The place available, can use bulk cans. Construction requirements of the warehouse: waterproof, moistureproof, avoid direct sunlight. Materials are taken off the ground and stacked overhead.

12. The temperature during construction should be higher than 5°C and the wind strength should not be greater than 4 level. In rainy days, construction is not allowed and protective measures should be taken.
