Influence of EPS filling methods and filling rates on thermal insulation performance of composite self-insulating blocks

Energy and the environment have the very close relationship. Many environmental problems depend on energy and economic development to solve step by step. One of the important measures to solve the problem of energy shortage is saving energy, economic development to relying more on energy saving of energy needed to solve, so building energy conservation has become the social issues of concern, and the key point of energy saving is on the retaining structure of the heating and cooling energy consumption. In this way, the thermal insulation and energy saving system of building envelope is increasingly strengthened.

In this study, the internal surface temperature and heat flow of each composite self-insulated block of the simulated wall were measured by the field detector of heat transfer coefficient of the building envelope of JTNT -a type, and the thermal properties of the six composite self-insulated blocks were compared and analyzed. The thermal insulation effects of the composite self-insulated blocks with different filling methods and filling rates were obtained. The following conclusions are obtained: The composite insulation wall with EPS has significantly better insulation effect than the wall without EPS, which is beneficial to the thermal protection of building envelope, reduces the heat loss from indoor to outdoor and energy consumption, and is of great significance. At the same filling rate, EPS should be filled as close as possible to the inside of the wall, which is more conducive to insulation effect.
