The Vapor Barrier is laid between the base course of the roof and the insulation layer, which can
strengthen the air-tightness and water-tightness of the building and slow down the speed of water
vapor discharging from the concrete structure and indoor moisture vapor discharging into the
insulation layer. "Specification" on the relevant provisions of the vapor barrier: the material of the
vapor barrier not only requires waterproof, but also requires the insulation of steam permeation,
so the provisions of the vapor barrier should be used air-tight, water-tight materials.

Water Vapor Isolation Function: Protect the thermal insulation layer and building structure
from the influence of moisture from the warm indoor environment, effectively control the heat
conduction and improve the building energy efficiency.
Prevention of Condensation: It is effective to avoid condensation, mildew breeding and damage
of thermal efficiency caused by the accumulation of water vapor in the insulation layer.Reduce risk
of mold and damage to building structures.
