What are the main building energy saving materials on the market at present?

The development and promotion direction of building energy-saving materials in China is to use a large number of new energy-saving materials in buildings, which have significant social, economic and environmental benefits, and have great potential. At present, the common energy-saving insulation materials in China mainly include rock wool, glass wool, polystyrene foam, cement polystyrene board, and silicate composite insulation mortar. Rock wool is an inorganic man-made fiber made of selected basalt or diabase as the main raw material and melted at high temperature.

Rock wool products have good thermal insulation, heat insulation, sound absorption, heat resistance, non-flammable properties and good chemical stability. Stone wool is used for building facades. There are three ways to insulate the diababatic:

Inner insulation, intermediate core insulation, and external insulation. Glass wool is the second largest category of mineral wool products, with silica sand, limestone, fluorite and other minerals as the main raw materials, after melting, with flame method, centrifugal method or high-pressure energy gas injection method, the molten glass is made into inorganic fibers. Glass wool products have good thermal insulation, heat insulation, sound absorption, non-combustible, corrosion resistance and other properties, and are widely used in housing, pipelines, storage tanks, boilers, aircraft, ships and other related parts of the insulation, heat insulation and sound absorption.

Polystyrene foam is a lightweight material made by heating and foaming with polystyrene resin as the base material, adding auxiliary materials such as foaming agents. It has the advantages of light weight, small thermal conductivity, low water absorption, water resistance, aging resistance, low temperature resistance, easy processing, low price and high quality. Now it is widely used in the construction market.

Cement polystyrene board is a new type of thermal insulation material made of polystyrene foam scraps or waste polystyrene foam by crushing particles, adding cement, water, EC foaming agent and foam stabilizer and other materials, stirring, molding and curing, which has the advantages of light weight, small thermal conductivity, good thermal insulation performance, certain strength and toughness, water resistance, flame retardant, convenient construction, firm paste, easy plastering, low quality, etc., and is suitable for the thermal insulation layer of building exterior walls and roofs. Silicate composite insulation mortar is a new type of wall insulation material, which is a gray-white viscous slurry made of selected sepiolite and aluminum silicate fiber as the main raw materials, with a variety of high-quality light body inorganic minerals as fillers, and under the action of several additives, it is deeply compounded by fine-fibrillation, diffusion expansion, miscibility, bonding and other processes. The salient features of this material are:

It has good thermal insulation performance, easy construction (direct application), and solves the cracking phenomenon of the covering layer at the plate splicing. Silicate composite insulation mortar has been listed as a key development object of new thermal insulation materials and products by the state.

Rubber-plastic boards, polystyrene boards, extruded plastic boards, polyurethane, rock wool, glass wool, these are the most used.

There are also some polyethylene, foam glass, and foamed cement that are not commonly used, and there are many that are not commonly used.

The important ones are divided into two categories: organic and inorganic. Tang Hao insulation, I hope to help you!
