If central heating is used, it will take a long time. If you choose an external wall insulation board with a thickness of 20mm, the effect will be better. It is necessary to pay attention to some extended floor heating, which is placed directly on the ground, so the premise must ensure that the ground is flat so that the ground and the insulation board can be tightly connected to ensure normal heating.

For finished coatings, it is rainproof before film formation, and it must be covered with color strips to prevent the formation of rain marks and sagging, which will cause pollution and rework. Protect downpipes and railings, railing ends and floors.

The thermal conductivity of non-insulating materials is generally large, the thickness is relatively fixed, and the adjustable range is not large. Therefore, the main control target of the external wall insulation energy-saving design is basically the insulation material, which can be simulated and calculated by energy-saving design software, and then calculated by adjusting the design type and thickness of the insulation material.

The cracks and bulges caused by the external wall insulation engineering design. For example, due to the corresponding thermal bridge effect at its location, if engineers and technicians fail to consider this layer in the design, the heat energy consumption of this layer is also a hidden danger of external wall insulation.

Due to the on-site spraying of the exterior wall insulation, an integral waterproof layer without joints is formed, which is better than any polymer membrane, thus reducing the maintenance workload. It is firmly combined with wood, metal, masonry, glass and other materials, and is not afraid of strong winds. The construction is simple and fast, and more than 200 square meters can be sprayed every day, which is conducive to the progress of the project.
