PP-Scrim-Kraft Facing

Posted on 04/03/2024


PSK Facing

PSK facing, also name as PP-Scrim-Kraft facing, it is a type of insulation facing material commonly used in HVAC (Heating, Ventilation, and Air Conditioning) systems and insulation applications. PSK stands for Polypropylene-Scrim-Kraft, which refers to the composition of the facing material.

PSK Facing Structure:

Polypropylene Layer: The polypropylene layer in PP-Scrim-Kraft Facing provides strength, flexibility, and durability to the facing material. It enhances tear resistance and overall performance, making the facing material robust and long-lasting.

Scrim Layer: The scrim layer in PSK facing is typically made of fiberglass and serves as a reinforcement component. The scrim adds strength to the facing material, improving its tear resistance and ability to withstand handling during installation.

Kraft Paper Layer: The kraft paper layer in PP-Scrim-Kraft Facing acts as a vapor retarder and provides additional strength to the facing material. It helps control moisture transmission through the insulation, reducing the risk of condensation and moisture-related issues.

PSK Facing Structure Features:

Moisture Barrier: PSK facing acts as a moisture barrier, preventing water vapor from penetrating the insulation material and protecting it from moisture-related damage.

Strength and Reinforcement: The polypropylene and scrim layers provide strength and reinforcement to the insulation facing, improving its performance in handling and installation.

Vapor Retardation: The kraft paper layer helps to control the transmission of water vapor through the insulation, reducing the risk of condensation and moisture-related issues.


Duct Insulation: PSK facing is commonly used in HVAC duct insulation to enhance thermal performance, moisture resistance, and protection against wear and tear.

Pipe Insulation: It is also applied in pipe insulation applications to improve insulation efficiency and protect against moisture infiltration.
Equipment Insulation: PSK facing can be used in equipment insulation to provide thermal protection and moisture control.

In summary, PP-Scrim-Kraft (PSK) facing is a versatile insulation facing material that combines polypropylene, scrim reinforcement, and kraft paper to provide strength, durability, moisture resistance, and vapor control in HVAC systems and insulation applications. Its composition and properties make it a valuable component in enhancing the performance and longevity of insulation systems.
