摘要
因为保温层的上部没有连续、致密的防水层/隔汽层,土建式冷库的倒置式屋面或双层钢板屋面的保温层上部应单设一道隔汽层,而TPO/EPDM单层屋面系统应用于装配式冷库项目时,因为TPO/EPDM防水卷材本身就是很好的隔汽材料,只要处理好接缝与收边,使单层屋面系统连续与密封,则没有必要在保温层的上部再另设一道隔汽层。
Because there is not continuous, dense waterproof layer / vapor barrier layer on insulation, a separate vapor barrier layer should be installed on insulation in inverted roof and double steel roof of civil cold storage. When using TPO/EPDM single ply roof system in fabricated civil cold storage, because the TPO/EPDM membrane itself is a very good vapor barrier layer, so the roof system needs not to install a separate vapor barrier layer on insulation, only needs to handle the joints and the closing side seams and makes single roof system continuous and sealing.
