1.Rock wool façade system.

The system structure mainly includes: adhesive layer, insulation layer, plastering layer, finishing layer and accessories. The finishing layer should be made of lightweight functional coatings such as finishing mortar and decorative mortar, or water-based exterior wall coatings with good air permeability.

Rock wool board external wall insulation system, low thermal conductivity, good air permeability, high combustion performance level and other advantages, composite A grade polyurethane external wall insulation board.

Composite A-grade polyurethane exterior wall insulation board.

It can be applied to the energy-saving and thermal insulation projects of the exterior walls of residential buildings and public buildings in new construction, expansion and reconstruction, including external wall thermal insulation, non-transparent curtain wall insulation and fire isolation belts of EPS external thermal insulation systems.

2.Polyurethane insulation.

Fire protection index of polyurethane exterior wall insulation system.

In September 2009, the "Interim Regulations on Fire Prevention of Exterior Wall Insulation System and Exterior Wall Decoration of Civil Buildings" was promulgated and implemented, which made clear requirements for the fire rating of building insulation materials. At present, the wall insulation materials commonly used in China are very flammable, and how to combine the high efficiency and energy saving of thermal insulation materials with excellent fire prevention has become an industry problem.

Polyurethane exterior wall insulation and fireproof system has outstanding fire performance, reaching the national A-level standard, fire and heat resistance, no melting, no dripping, low smoke at high temperature, good dimensional stability, and has a good thermal insulation and energy-saving effect, which combines excellent fire performance and good energy-saving effect, and is suitable for external wall insulation and many other fields.

Pay attention to the mobile phone Zhongda Consulting (, real-time understanding of the latest developments in the construction industry.

1. Construction quality inspection methods and standards.

1) After the completion of each process, check the flatness in all directions with a 2m flat ruler, and check the verticality with a line drop ruler, and the standard is that the deviation between the vertical and the entrainment degree is not more than 3mm.

2) The thickness deviation of the insulation layer is checked by acupuncture method to determine whether the actual thickness of the insulation core board meets the design requirements.

3) random sampling inspection, every 100 random inspection points, if the point does not meet the design requirements, then increase the sampling inspection points for every 30 points, and make a record, to be made mathematical statistics, evaluate the quality.

Exterior wall insulation construction technology and acceptance specifications.

Exterior wall insulation construction technology:

1.Surface treatment: clean the oil, dust and loose matter on the surface of the exterior wall, and polish it evenly.

2.Foundation treatment: Deal with the waterproof, moisture-proof and thermal insulation of the foundation parts.

3.Gluing: Use a professional adhesive film machine to apply the glue to the surface of the exterior wall to ensure tightness.

4.Fixing the insulation board: After positioning the prefabricated insulation board, fix it with an angle iron or nails.

5.Seam Treatment: Treat the seams between the insulation panels to ensure that the seams are tight and seamless.

Acceptance specifications:1Check whether the thickness of the insulation board meets the design requirements.

2.Check the fixing condition and bonding quality of the insulation board.

3.Check whether the thickness of the air layer between the insulation layer and the wall base layer meets the requirements.

4.Check whether the insulation construction meets the requirements of the specification.

5.Acceptance of the color, flatness, bonding firmness and other items of the finishing layer.

In fact, this standard is different, but our masters do things according to experience, because each project can not guarantee that the wall is 100% flat, and of course, the thickness of each insulation board cannot be the same.

It is very necessary for the construction acceptance of building exterior wall insulation materials, so that relevant quality problems can be found in time during and after construction, the quality accident rate of the insulation system can be controlled, and the performance and safety of the system can be ensured. The acceptance process of building exterior wall insulation construction mainly includes: construction quality inspection methods and standards, insulation engineering quality assessment and acceptance standards, and the following is a specific introduction to the two specific inspection methods of the process.

1. Construction quality inspection methods and standards:

1. After each process of insulation construction is completed, it is necessary to check the flatness of the light body in each direction with a flat ruler. Check the verticality with a line drop ruler, and the deviation between the vertical and the entrainment is 3mm;

2. To check the thickness of the insulation layer by acupuncture, the design regulations of the composite insulation system are required;

3. Random inspection checkpoints, if the checkpoints do not meet the design requirements, it is necessary to increase the sampling checkpoints to set one point for every 30, and make a record to be made for mathematical statistics to evaluate the quality;

4. The quality inspector needs to check the quality control in the construction operation, and focus on controlling the quality of the process before the next process can be constructed.

Second, the project quality assessment and acceptance standards:

1. Observe with the naked eye whether the surface of the external wall of the building is smooth and smooth, whether there are traces of repair, and whether there are stubbles;

2. The overall surface of the exterior wall needs to be free of cavities, house cracks, spots, and good color and appearance;

3. Check whether the yin and yang angles are vertical and square, and whether they meet the quality requirements;

4. Check whether the verticality and surface flatness of the façade are within the specified allowable deviation.
