Basic Vapor Barrier

Brand :Panzhu

Product origin :Dawang Village, Dacheng County, Langfang, Hebei, China (Mainland)

Delivery time :15 days

Supply capacity :100000m²

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.

                 Three layers of the reflective insulation membrane


Vapor Barrier

Insulation films can be classified into two categories according to insulation technology.

1. Endothermic insulation membrane

Working principle of absorbing membrane and reflective foil insulation

Working Principle: Use the absorbent coated on the surface of transparent polyester film to absorb infrared heat to achieve the purpose of heat insulation.

2. Reflective insulation membrane

Working Principle: The transparent polyester film was sputtered with multi-layer precious metals to make a high thermal insulation metal film to reflect the infrared heat to achieve the purpose of thermal insulation.

Reflective insulation membrane is an intelligent spectral selective insulating film which can achieve the purpose of heat insulation by reflection. Its appearance solves the problem of secondary radiation heat transfer, which is a congenital defect of endothermic insulating film.   It uses magnetron sputtering technology to sputter gold, silver, titanium, nickel, indium and other precious metals evenly onto the optical grade PET substrate to make a multi-layer and dense high thermal insulation metal film, whichhas a lasting reflection and insulation effect on the infrared heat in the solar spectrum. It is widely used in automobile, building glass and other industries.
