墙体节能的关键是如何选择和合理应用高效保温材料,使其发挥最佳的保温效果。在选择材料时不仅要考虑材料的导热系数,同时要舍弃那些易吸湿的材料;同时选择配套的保温体系,防止超量冷凝水在保温材料边界形成,使节能墙体始终保持有效状态。 The key to energy saving wall is how to choose and reasonably use efficient insulation materials, so that it can play the best insulation effect. When selecting materials, not only the thermal conductivity of the material should be considered, but also those materials that are easy to absorb moisture should be discarded. At the same time, the matching insulation system should be selected to prevent excess condensate from forming on the boundary of the insulation material so as to keep the energy-saving wall in a valid state all the time.
