  A new high-performance thermal insulation material, foam glass, has begun to be applied in construction engineering. Foam glass has been widely used in foreign countries for insulation and insulation of roofing and exterior walls of chemical insulation, shipbuilding, refrigeration, cold storage, subway and constant temperature and humidity engineering, and general industrial and civil buildings. In the past, China has only used thermal insulation projects for chemical deep-cooling equipment, ships, and cold storage. In recent years, it has begun to be used in construction projects.
  Foam glass is a light-weight, independent closed-cell foam that is produced by firing quartz sand ore powder or cullet. Because it is a closed-cell foam glass of inorganic material, it has small thermal conductivity and stable adiabatic function; no water absorption, low water vapor permeability; excellent high temperature resistance and durability; high strength, light weight, small deformation; no burning , non-corrosive; can be cut and formed, easy to construct; can be made into colored materials, with landscaping functions. The polymer cement mortar can be firmly bonded to the base layer.
  Compared with the insulation materials currently used in construction projects, foam glass has unique characteristics for roofing, can form a permanent thermal insulation layer, and, because of its excellent weather resistance, is especially suitable for inverted roofing. Thermal insulation layer. After the polymer cement mortar is bonded and jointed, a complete waterproof layer can be formed to protect the water. When used for exterior walls, it can be directly bonded with polymer cement mortar, which is convenient for construction. For example, the use of colored foam glass not only serves as thermal insulation but also as a decorative material, it is a good way to do it.。
  Building energy conservation is an extremely important policy of the country. It is a systematic project to benefit the country and benefit the future generations. Strengthening the thermal insulation of buildings to improve people's working and living environment conditions and saving energy is both direct and practical. In China's building thermal insulation engineering, high water absorption and poor durability of thermal insulation materials have always been two major problems. It greatly reduces the insulation performance of the material, affects the effect of thermal insulation, and increases the energy consumption of the air conditioning system. Moreover, after the water is absorbed, the heat insulating layer becomes an aquifer, which causes the waterproof layer to be damaged by the drum, causing leakage, and leaking water for a long time after the rain. In the external wall structure, due to the need of thermal insulation, the wall needs to be thickened to meet the functional requirements. Since there is no thermal insulation material that can replace the original red brick as the wall material, only the external insulation material can be used for insulation. Insulation, so it needs lightweight, good insulation, anti-aging, non-absorbent, easy to bond materials, foam glass is an ideal insulation material. Foam glass, whether used for roofing or exterior walls, is an excellent thermal insulation material.。
