The outer wall thermal insulation technology first originated in Europe. China began to pilot it in the mid-1980s, and it is widely used in the construction field. In recent years, with the continuous in-depth development of energy-saving work for housing construction in China, and the continuous improvement of energy-saving standards, many new types of energy-saving technologies and materials have been introduced and developed, and are being promoted and used in residential buildings. So, what are the external wall insulation materials and the price of external wall insulation materials ? Let's take a look with Xiaobian.
What are the external wall insulation materials
External wall insulation materials are divided into inorganic and organic according to their compositional performance. In general, organic insulation materials have very good thermal insulation effects, but their fireproof performance is low. Inorganic insulation materials have good fireproofness, but their insulation effect is extremely poor. What are the wall insulation materials?
First: Benzene plates and benzene plates are now used more often, but their thermal insulation effect is not ideal, and they will absorb water. Therefore, when using benzene plates, some waterproof measures are generally used.
Second: extruded board, extruded board is much better than benzene board, thermal conductivity lower than the benzene board, the price is slightly higher.
Third: Polyurethane is a kind of relatively high-end insulation material, and it is also the best kind of performance. Generally, it is used in some places where the requirements are extremely strict, and because it has a high price, there are fewer houses.
Fourth: Glass wool and rock wool, glass wool and rock wool have many similarities in performance. Many people are also easily confused. However, because glass wool is better than rock wool, its price is generally higher than that of rock wool.
New exterior wall insulation material:
First: XPS extruded polystyrene foam sheet. Also known as polystyrene extruded board (abbreviated as XPS); has a perfect closed-cell honeycomb structure, its density, water absorption, thermal conductivity, and steam permeability coefficient are lower than other types of plate-shaped insulation material, so it has strength Good, light, airtight, corrosion-resistant, anti-aging, low price, etc., are widely used in the construction industry of thermal insulation, highways, railways, airports, squares of antifreeze insulation, home decoration and other fields.
Second: thermal insulation mortar. Thermal insulation mortar is a kind of premixed dry mortar made of various lightweight materials as aggregate, cement as cement material, blended with some modified additives, and mixed by the production enterprises. Mainly used for building external wall insulation, has the advantages of convenient construction and good durability.
Third: phenolic foam. Phenolic foam is a new type of insulation material that has been recognized as one of the most promising buildings in the world. Because this new material is essentially different from the material used in the conventional polymer resin by adding flame retardant. It does not burn in the fire, does not melt, does not emit toxic fumes, and is light, non-toxic, and non-toxic. Corrosion, insulation, energy saving, sound insulation, low cost and other advantages.
Fourth: EPS board. EPS board, also known as benzene board, foam board, is the abbreviation of expandable polystyrene board. It is made of expandable Polystyrene, pre-fabricated, cured, formed, dried and cut. It can be made into foamed plastic products of different densities and shapes, and can also produce foam boards of various thicknesses.
Pipe insulation material:
First, mineral wool, including rock, slag, etc., can be used for all pipe insulation—especially for higher temperature industrial pipes, which is also the most widely used pipe.
Second, elastic foams, rubber foams are widely used in the insulation of refrigeration and air conditioning pipelines, and because of their characteristics, they are often used in the insulation of heating systems.
Third, polyethylene is the most widely used material in Chinese families to prevent the freezing of household water pipes.
For the choice of insulation material, we must be cautious and careful, once applied properly, it is prone to problems, and because it is a hidden project, you want to repair, the difficulty is relatively large.
External wall insulation material price list
The price of exterior wall insulation mainly consists of the following components: 1. Material fees, 2. Labor costs, 3. Management fees and taxes, etc. We understand the specific composition:
