What are the Different types of Building Insulation?

There are many types of thermal insulation materials used in buildings. Among them, the most commonly used thermal insulation materials are two types: inorganic insulation materials include expanded perlite, aerated concrete, rock wool, glass wool, etc .; organic insulation materials include polystyrene Foam, polyurethane foam, etc.

There are many types of thermal insulation materials used in buildings, of which the two most common types of thermal insulation materials are used: inorganic thermal insulation materials are

Generally speaking, the common characteristics of thermal insulation materials are light, loose, porous or fibrous, and the air that does not flow inside to block the conduction of heat insulation. Among them, inorganic materials have the characteristics of non-combustibility, wide use temperature, and good chemical resistance. Organic materials have the characteristics of lower water absorption and better water resistance.

Building insulation materials can effectively suppress the radiant heat of the sun and infrared rays, and the heat insulation suppression efficiency can reach about 90%. In the open sun, the temperature of the radiated surface can be reduced by more than 30%. It can restrain the heat radiation and heat loss of high-temperature objects, keep 70% of the indoor heat, and effectively keep cold for low-temperature objects, and can suppress the loss of cold caused by radiant heat from the environment, and prevent condensation from occurring.

Building insulation materials can not only effectively insulate heat, but also have excellent waterproof, moisture-proof, anti-corrosion, anti-ultraviolet aging, acid and alkali resistance, salt spray resistance and other properties. The material has no harmful substances, high solid content, ductility, Good adhesion, easy construction, long service life, etc., and the coating film has lotus leaf hydrophobicity and excellent self-cleaning function. It can be widely used in construction, chemical industry, petroleum, electric power, metallurgy, shipbuilding, textile, storage, transportation, Aerospace and other industries.

As a new type of energy-saving material, building insulation material has been widely used in the construction field with its good heat insulation performance, less energy consumption required for heat insulation, and better occupancy comfort. Research results. However, under the condition of maintaining good thermal insulation, the building structure ignores the technical requirements of the building structure in terms of fire prevention, which makes the overall design of the building unreasonable and uneconomical. ^[1]
