Proboard Plus Enstron 4×8 3/8″

Stable, Quiet, and Comfortable Base for Floating Floor Installations.

The Proboard Plus Enstron 4×8 3/8″ is a rigid underlayment panel designed to improve the performance and feel of floating floor systems. Installed between the subfloor and finished flooring, it helps reduce sound transmission, smooth minor surface imperfections, and create a more stable base for installation.

This panel is commonly used under laminate and engineered hardwood flooring, especially in multi-level residential settings where impact noise reduction is important. Its dense engineered construction helps absorb sound while adding a slightly cushioned feel underfoot, improving overall comfort in living spaces.

At 3/8″ thickness, Proboard Plus provides more substantial support compared to thin roll-out underlayments. It can help compensate for small irregularities in the subfloor, contributing to a flatter, more consistent surface for flooring installation.

The 4×8 sheet format allows for efficient coverage of large areas and straightforward installation using standard cutting and fastening tools. It is suitable for both wood subfloors and properly prepared concrete surfaces when used as part of a complete flooring system.

Key Features of Proboard Plus Enstron 4×8 3/8″:
Rigid panel underlayment for improved floor stability, reduces impact noise between floors, helps smooth minor subfloor imperfections, enhances underfoot comfort, suitable for laminate and engineered hardwood installations, and easy-to-handle 4×8 sheet format for efficient installation.

Pro Tips:
Ensure the subfloor is clean, dry, and level before installation. Stagger panel joints and leave small expansion gaps as recommended. Do not install over flooring systems that already include attached underlayment, as excess cushioning can lead to joint failure.
