Product Description
1. Product Description
Polysurlyn Moisture Barrier (PSMB) is a multi-layer material that is applied as a vapor barrier and thermal insulation to the inner surface of metal building panels.
The purpose of a vapor barrier is to prevent moisture from penetrating into the insulation and potentially causing damage or mold growth within the building. The thermal insulation helps to prevent heat loss and increase energy efficiency.
PSMB typically consists of three layers: a layer of polyethylene, a layer of aluminum foil, and a layer of polysurlyn (a co-extruded film of polyethylene and aluminum). The aluminum foil layer serves as the vapor barrier, while the polyethylene layer and polysurlyn layer provide additional durability and protect the aluminum from punctures or tears.

2. Applications
1.Insulation for metal building panels:
PSMB is applied to the inner surface of metal building panels to provide insulation and prevent moisture penetration. This can help to increase the energy efficiency of the building and prevent damage to the insulation or growth of mold.
2.Lining for HVAC systems:
PSMB can be used as a lining for heating, ventilation, and air conditioning systems to prevent moisture from penetrating the ductwork.
3.Insulation for roofs and walls:
PSMB can be used to insulate roofs and walls in both residential and commercial buildings. This can help to prevent heat loss and increase energy efficiency.
4.Insulation for piping:
PSMB can be used as an insulation wrap for pipes, particularly those that carry hot fluids. This can help to prevent heat loss and improve the energy efficiency of the building.
5.Protection for metal structures:
PSMB can be used as a protective layer for metal structures such as pipelines, tanks, and storage vessels. The aluminum foil layer can help to protect the metal from corrosion and damage.
