The exterior wall insulation is various, and the traditional exterior wall insulation is compounded by polymer mortar, glass fiber mesh cloth, flame-retardant molded polystyrene foam board (EPS) or extruded board (XPS) and other materials. Site bonding construction. The new type of insulation and decoration integrated board is produced through assembly lines and integrates functions such as heat preservation, waterproofing, and facing. It is the preferred material for meeting the current energy efficiency requirements for building construction, improving the external wall insulation level of industrial and civil buildings, and also energy saving for existing buildings. The preferred material for the transformation. Many people do insulation during the renovation of the external walls. Insulation can make our house not so cold, but there are many materials for insulation. Therefore, we must first select materials and then learn how much the price per square meter of external wall insulation is. ? What are the problems with external wall insulation precautions? Don't worry. What is the price per square meter of insulation on the outside wall ? What are the precautions for external wall insulation? Here's what I have come to reveal for you.
What is the price per square meter of external wall insulation?
It is very important to choose the insulation material for the external wall. If you choose not to keep the insulation, it becomes a display. It is very simple to know how much the external wall insulation price per square meter is. We must first determine what the choice of insulation material is. The insulation material is not the same, so we can not talk about it.
What are the precautions for external wall insulation?
1. Precautions for external wall insulation—The external wall insulation material and the base wall shall be reliably fixed. High-rise buildings should withstand large wind loads. The insulation layer should have a reliable bond with the base layer (inorganic materials), especially the use of (organic materials) insulation board, we must pay attention to this link. The insulating layer made of inorganic materials, such as the Ito building insulation system, has good compatibility and compatibility with various types of base walls (inorganic concrete, various types of wall materials, etc.); it is also under the influence of wind loads. It will not be deformed or peeled off, with a high degree of safety and reliability.
2. External wall insulation precautions - The fire performance of the system should comply with the relevant national laws and regulations. Nowadays, fire-retardant polystyrene boards are used for the outer insulation of high-rise buildings. These materials are flammable. Fire-proof construction measures should be taken for the outer walls of high-rise buildings, such as setting fire barriers. Compared to such organic insulation materials, Yitong insulation system has excellent fire resistance and flammability and will not produce toxic gases. According to the testing of the relevant agencies of the country, the fire resistance limit of Yitong insulation block can reach more than two hours.
3. Precautions for external wall insulation – The outermost surface layer should be painted (or colored mortar). The insulating layer in the system is mostly lightweight porous material with low shear strength, so the facing layer should not use tiles. Such as adhesive tiles must have reliable measures to prevent the tiles from falling off and hurting people. The Ito insulation system has a protective layer on the surface for reinforcement, with high strength and excellent impact resistance.
4. External wall insulation precautions - The durability of the system should meet the requirements. Under normal use and maintenance conditions, the service life of external wall insulation works should be no less than 25 years. Insulation system main material is inorganic silicate material, with excellent anti-aging properties, life and concrete and inorganic materials, other insulation materials can not be compared.
External wall insulation construction scope
1. The scope of application of this regulation: Polystyrene board is used as insulation material, polymer adhesive mortar is used as bonding material, polymer screed mortar is used as wiping layer, and alkali-resistant glass fiber is coated with plastic mesh as reinforcing material and supplemented with card.

8. Remove all obstructions on the wall surface to be insulated.
9, the wind when the insulation board is not more than 5 levels.
10. To ensure construction quality, the construction surface should avoid direct exposure for a long time, and it should not be constructed in rainy days.
11, construction tools: slotting machine, wallpaper knife, screwdriver, scissors, ink fountain, brown brush, electric mixer, plastic, mixing barrel, impact drill, hammer, trowel, pallets, 2m on the ruler.

External wall insulation construction quality acceptance standards
1, construction quality inspection methods and standards
(1) After completion of each procedure, check the flatness of each direction with a 2m flat panel and check the verticality with a line falling ruler. The standard deviation between vertical and entrainment is no more than 3mm.
(2) The deviation of the thickness of the insulation layer is checked by acupuncture, and the actual thickness of the insulation core board is determined to meet the design requirements.
(3) random sampling inspection, every 100m2 sampling points, if the point does not meet the design requirements, increase the sampling checkpoint to set a point every 30m2, and make records, to be used for mathematical statistics, quality assessment.

Rainwear is
Raincoat or rainsuit which is a waterproof or water-resistant coat worn
to protect the body from rain. The term rain jacket is sometimes used to
refer to raincoats that are waist length. A rain jacket may be combined
with a pair of rain pants to make a rain suit.
Modern
raincoats are often constructed of breathable, waterproof fabrics such
as Gore-Tex or Tyvek and coated nylons. These fabrics allow some air to
pass through, allowing the garment to 'breathe' so that sweat vapour can
escape. The amount of pouring rain a raincoat can handle is sometimes
measured in the unit millimeters, water gauge.
