The basic structural level of the foam glass exterior wall external insulation system should be from the inside to the outside: bonding layer, foam glass insulation layer, protective surface layer, and decorative layer. Among them, the plaster layer is mainly used for the leveling of the base layer of the wall to ensure The foam glass is firmly pasted on the wall, and the surface protection layer is mainly to protect the firmness of the reinforced insulation system and prevent water seepage.

The thickness of the foam glass insulation layer shall be determined by calculation according to the material and thickness of the base layer of the outer wall and the energy-saving requirements of the outer wall. The foam glass exterior wall thermal insulation structure can be combined with the exterior wall thermal insulation structure of other organic materials as the thermal insulation layer, as a fire barrier to prevent the external wall from burning.

1. Application of foam glass in the field of building energy saving

1. Building roof insulation. There are three main forms of foam glass used in building roof insulation structure: upright roofing, inverted roofing, and inclined roofing. The inverted roof can be used for greening, planting flowers and plants; or as a roof sports field and other roofs. Foam glass is easy to combine with other inorganic materials, easy to construct, and has better waterproof, fireproof and thermal insulation effects.

2. Building thermal insulation material Foam glass as a wall thermal insulation material can effectively reduce the thickness of the wall, reduce the weight of the building structure, and expand the use area. Use foam glass for external wall insulation structure. During construction, firstly, use polymer mortar to paste foam glass on the leveling layer of the outer wall; secondly, apply mortar layer or tile decoration layer on the surface of foam glass.

3. Foam glass outer insulation and construction technology The foam glass outer wall insulation technology uses a special adhesive to bond the foam glass to the base wall, the surface layer is leveled with anti-cracking mortar, and the finish layer is painted or facing bricks, etc. The form is decorated to improve the overall fire resistance and thermal insulation performance of the building envelope. Especially for high-rise residential buildings and public buildings with high fire resistance requirements, this technical system further proves its practical application significance.

The construction system of foam glass exterior wall thermal insulation technology is composed of foam glass bonding layer, foam glass insulation layer, anti-cracking mortar leveling layer, alkali-resistant glass fiber mesh cloth or square steel wire mesh anti-cracking mortar insulation layer, and finishing layer.
