Construction Sheathing - Richflor Underlayment

Richply Richflor Underlayment is a premium grade Douglas Fir intermediary or sub-surface layer of plywood typically installed on top of a subfloor to provide a smooth, consistent surface suitable for the additional installation of a variety of floor coverings.

Richflor Underlayment is a specially developed solid-face premium-core underlayment sanded to fine tolerances for a smooth, stable and puncture-proof surface that readily accepts adhesive and is easy to install. It will not cause cracking, shrinking, bleed-through, or discolouring of the finished floor.

Richflor Underlayment is a Douglas Fir panel produced to CSA-0121 and US PS-1 product standards.

Applications:

  • Puncture Resistant – premium grade core veneers and minimal core gaps serve to prevent punctures.
  • Stability and Durability – certified panel construction by AFA as meeting or exceeding CSA standards, bonded under high temperature and pressure with a waterproof phenol-formaldehyde resin adhesive, Richflor U-Lay is a highly stable and durable panel guaranteed against delamination and discolouration.
