ROBERTS Unison Premium 2-in-1 Underlayment – 100 sq ft for Laminate & Engineered Wood

Overview

Roberts Unison Premium 2-in-1 Underlayment is built to cradle floors from the ground up. Designed for laminate and engineered wood, it combines a soft 3/32 inch polyethylene foam cushion with a durable 2 mil top film to guard against moisture vapor. This two-layer approach helps create a stable base underfoot and a smoother surface for your flooring installation.

The product supports a range of spaces, from living rooms to home offices, and is suitable for on- or above-grade applications. When used below grade, pair it with a proper moisture barrier to maintain performance over time.

Key benefits at a glance

• Cushioned underfoot that enhances comfort and reduces foot fatigue
• Closed-cell foam resists moisture, mold, and mildew for longer-lasting floors
• Top film acts as a moisture barrier to protect flooring vapor exposure
• Suitable for radiant heated floors, helping maintain warmth and comfort
• Lightweight and easy to handle, with overlap edges and adhesive strips for clean seams

Practical uses and installation tips

During installation, roll out the underlayment and align the edges, using the plastic overlap and adhesive strip to join rolls. Avoid gaps and overlaps that could interfere with floor performance. The material’s low profile cushions the floor, yet remains compact enough to prevent excessive bulk under planks.

• Lay flat and align with room dimensions to minimize waste
• Use the adhesive strip to create seamless transitions between rolls
• Ensure surfaces are clean and dry before laying flooring on top
• For below-grade spaces, install with a compatible moisture barrier as required
