Plastic Sheet Underlayment – Moisture Barrier & Floor Protection Layer

A plastic sheet underlayment is a thin plastic installed beneath flooring materials (like SPC, laminate, or engineered wood) to serve as a moisture barrier, vapor control layer, or basic cushion. It plays a crucial role in ensuring the longevity and stability of the floor, especially over concrete subfloors.

Application:

• Moisture Barrier : Prevents moisture from rising up from concrete or ground into your flooring
• Vapor Control : Reduces condensation and mold buildup beneath floating floors
• Basic Cushioning: Provides slight softness and sound reduction when walking
• Smooth Substrate Layer: Helps level out small imperfections on the subfloor

Specification:

Important Note:

Plastic sheet underlayment is not a substitute for foam underlay. It’s typically used in combination with other layers (like PE or EVA foam) for complete performance.
