B. Improve the energy saving and insulation effect. Due to
     the unique water proof and vapour permeable
     performance, when forming the protection to the
     insulating layer, it can also effectively avoid the negative
     influence from the temperature difference between interior
     and exterior. hence, it increasing the effects of
     insulation and energy saving as well as providing the
     continuously energy saving

C. Shorten the construction period. Thanks to the good
     water resistant performance, interior construction and
     exterior can be performed at the same time so that
     reduce the construction period, reduce the construction
     cost.

D. Improve the residential environment. Because of the
    special breathable function, the interior vapour can natural
    exhaust, will effectively avoid mould and condensation,
    keep dry, permeate and comfortable indoor, improve the
    residential environment.
