水会因其建筑外墙保温系统防护层的湿胀，湿胀变形会因其开裂。
水会加剧外墙外保温系统防护层砂浆及界面微裂纹的扩展，降低粘接强度。
水在建筑墙体保温材料防护层内部的迁移会加快防护层的老化，如碳化、泛碱。
水会降低建筑外墙外保温系统防护砂浆中聚合物与基材的粘接力。
水化加快建筑外墙外保温系统扩护砂浆中水泥的水化，防护层脆性提高，抗冲击强度及柔性降低，开裂风险增加。
水在高温下变成水蒸汽时产生体积膨胀，如果腻子涂料防护系统中涂料透气性不好，会因其涂料的起鼓与剥离。
水汽在系统内迁移并在不同界面及材料中结露会导致系统粘接强度降低。
水汽进入较疏松的保温材料中，会引起保温的内聚力下降，导致系数达增加。
水结冰会产生膨胀应力，不仅大幅度降低防护材料本身的强度，引起开裂，而且还会降低粘接材料在界面处的粘接强度，如瓷砖剥离，抹面开裂、脱落等。
Water is because of the protective layer building external wall thermal insulation system of wet bilge, bulking deformation due to its cracking.
Water will intensify exterior insulation system protection layer of mortar and interface micro crack extension, reduce the bonding strength.
Water migration in the inside of the building wall insulation protective layer can accelerate the ageing of the protective layer, such as carbonization, whiskering.
Water will reduce the protection mortar building exterior insulation system of polymer and the base material of stick relay.西宁保温材料|西宁防水材料|青海保温
Hydration speed up the building exterior insulation system expansion of mortar cement hydration, the protective layer of brittleness, impact strength and flexibility is reduced, increased risk of cracking.西宁保温材料|西宁防水材料|青海保温
Water turns into steam at high temperatures generated when volume expansion, if be bored with child protection system in the coating permeability is bad, because of the paint of the drum and stripping.西宁保温材料|西宁防水材料|青海保温
Water vapor in the system transfer and condensation with different materials and interface bonding strength can lead to system down.
Water vapor into a porous thermal insulation material, can cause thermal loss of cohesion coefficient of increasing.西宁保温材料|西宁防水材料|青海保温
Water freeze will produce expansion stress, not only greatly reduce the strength of the protective material itself, cause craze, but also reduce the bonding material in the interface bonding strength, such as ceramic tile, plaster cracking, peeling, etc.
