The temperature in the winter is declining. Many consumers choose to do insulation measures on the outer wall of the house to ensure the warmth of the room. Especially in the north, the insulation of the external wall of the house is very important, and it is one of the main ways to keep out the wind and protect the cold.
There are many ways to protect the external wall, and there are many things to be aware of. If it is not properly treated, it will cause leakage in the insulation system, causing the indoor insulation effect to be unsatisfactory. What should be paid attention to in the external wall insulation? How to solve it correctly? The coatings here are elaborated on the external wall insulation, and it is hoped that consumers who are preparing for external wall insulation will be helpful.
The most problematic place for exterior wall insulation projects is the most easily overlooked places for consumers. The main points are as follows:
The construction season should be selected
Do not allow the external wall insulation to be done in winter. It is necessary to choose a reasonable time season. Generally, autumn is most suitable. The autumn is high, the temperature difference between day and night is not the most suitable for outdoor construction, and the drying time of the film will be shortened a lot.
External wall substrate needs to be treated
The treatment of the outer wall base is one of the most basic tests for the service life of the insulation system. If the base surface of the outer wall is dirty, the pit is uneven, there are crack defects, etc., the unreasonable treatment will lead to the insulation system and the wall. The adhesion is reduced, causing cracking, shedding, leakage, etc. to affect the indoor insulation effect.
Side seam angles are taken into account
The side seam angle is the most likely to cause cracking. It is also the most overlookable place during construction. Many exterior wall insulation systems are still very good in the short term, but after a while, it will feel that the house is not so warm. Attentive consumers will find that there are many small cracks in the joints such as the door frame and the window sill. It is obvious that the coldness of the wire comes in from the gap, so there is no effect when the insulation system is just finished. All right. Strict inspection must be carried out during construction.
Material selection should be cautious
The insulation effect of different materials is also different. The reasonable material is also a guarantee of the insulation effect. For example, the simple cotton felt can only block the cold wind, but it can not guarantee the invasion of cold and the loss of indoor temperature. The insulation effect will not be too it is good. Therefore, the insulation effect is good, and the use period is long. It is recommended to use thermal insulation coating for exterior wall insulation. The Repham brand insulation coating is a new type of building insulation and cold protection product. It has the advantages of good thermal insulation effect, simple construction, long-term use and high cost performance. Many northern consumers use exterior insulation measures.
As a filler metal welding wire or both as a conductive wire welding materials used. When gas welding and gas tungsten arc welding, welding filler metals used; in submerged arc welding, electroslag welding and other time MIG arc welding, welding filler metals both, but also conductive electrodes. Surface oxidation coated wire is not the role of flux.
