Insulation construction of roof inner wall and outer wall Polyurethane insulation material equipment

What are the acceptance criteria for exterior wall insulation?

The acceptance of external wall insulation construction can be divided into main control items and general items. Acceptance methods and standards are as follows:

Main control items of polyurethane insulation material equipment for roof inner wall and outer wall insulation construction

The materials used in the insulation system must meet the design requirements and the relevant provisions of this regulation.

The structure and details of the thermal insulation system of the thickness of polyurethane equipment insulation board for external wall insulation in building construction should meet the requirements of building energy-saving design. The allowable deviation of the thickness of the insulation layer (design thickness) is +0.1, and the insulation layer must be firmly bonded to the wall. The plastering glue and the insulation board must be firmly bonded, and the surface layer has no defects such as ash and cracks.

General Precautions for Polyurethane Insulation Materials and Equipment for Roof Inner Wall and Exterior Wall Insulation Construction

1. Alkali-resistant mesh should be compacted, the overlapping width should not be less than 100mm, and the alkali-resistant mesh should be strengthened. Practice should conform to design requirements.

2. The surface of the insulating layer and the plastering layer should be flat and clean, and the line corners should be straight and clear.

3. Pay attention to the allowable deviation of the insulation board installation and the allowable deviation of the plastering layer.

During the processing and use of polyurethane spraying equipment, whether it is a plane or a top surface, whether it is a circle or a sphere, or some other complex objects, it can be directly sprayed, and the polyurethane insulation material equipment for roof inner wall and outer wall insulation construction can be directly processed. Any expensive expenses manufacturing costs. The polyurethane spray insulation of the exterior wall itself has a series of insulation layers, and its shape is basically in the same range as that of some materials, and there is no seam at all when it is actually sprayed. It can be said that their insulation effect is very good, and there is even a very good insulation skin on the outer layer, which can well protect the inner material.

The building’s external wall insulation engineering construction project has enabled the house to realize the function of being warm in winter and cool in summer. Polyurethane spraying exterior wall insulation is an enterprise with secondary insulation construction qualification. It has provided external wall insulation engineering construction services for many buildings, and hopes to contribute to the development of human beings.

Now, with the continuous development of the economy, the number of buildings in the city continues to increase, and the government has also issued a document requiring the insulation of the exterior walls of all new buildings. In Shanghai and other economically developed cities, the government has also successively required existing buildings to carry out energy-saving renovation of external walls to promote energy conservation and emission reduction. In rural areas, building external wall insulation engineering has also been vigorously applied, and now most of the newly built urban communities or rural villas use external wall insulation.
