Thermal insulation materials and building insulation materials

As for what insulation materials, building insulation materials and building exterior wall insulation materials are, let's give a brief introduction to their concepts below.
What is thermal insulation material
The thermal insulation material refers to a material or material composite that has significant resistance to heat flow. The thermal insulation performance of a material is determined by the thermal conductivity of the material. The smaller the thermal conductivity, the better the thermal insulation performance.
What are building insulation materials
Various insulation materials used to build energy-saving buildings are called building insulation materials. Mainly include roofing, wall insulation materials and energy-saving windows.
What are building exterior wall insulation materials?
Insulation materials used for building exterior wall insulation and energy saving.
There are many varieties of thermal insulation materials, which can be divided into three categories according to materials: inorganic thermal insulation materials, organic thermal insulation materials and metal thermal insulation materials. According to the shape, it is divided into several types: fibrous, porous (micropores, bubbles), lamellar, etc. Currently, fibrous insulation materials such as rock wool boards, glass wool, aluminum silicate wool, etc., which are widely used in my country's construction market, and their products are made of wood fiber, various plant straws, waste paper and other organic fibers as raw materials. Fiber panels; porous insulation materials such as expanded vitrified microspheres, expanded perlite, microporous calcium silicate, foamed asbestos, foamed glass and aerated concrete; foamed plastics such as polystyrene, polyurethane, polyethylene and phenolic boards, etc. ;Layered insulation materials such as aluminum foil, various types of metal or non-metal coated glass, and coated products made of various fabrics as base materials.
Building insulation materials are one type of insulation materials, and building exterior wall insulation materials are one type of building insulation materials. </p
