Stabledge Sub-Flooring: The Premium Edge in Sub-Flooring. By Norbord Industries.

Installation

Norbord structural panels are to be installed according to the APA's (The Engineered Wood Association) Construction Guide E30, the appropriate building code and/or the design professional's specifications. Below are some key installation points and tips.

  • Space panels 1/8" apart on the 4' edges (Using a 10d nail as a space guide is a quick and easy way to ensure spacing)
    Space subfloor panels 1/8 of an inch apart on the 4-foot ends of the panels by butting the panels together.
  • Lightly butt the T&G together
  • Ensure the joists are aligned, uniform and square
  • Install panels with the major strength axis perpendicular to supports.
  • Install T&G panels with the APA grade stamp down.
  • Fastener Spacing — consult your local building codes for local requirements, the APA Construction GuildeE30 and/or your design professional's specifications.
  • Gluing subfloor panels is recommended and may be required. We recommend the use of PL 400 subfloor adhesive. At a minimum sub-floor adhesives must meet current industry test standards. If glue is used apply only enough glue to install 2 or 3 panels at a time and fully fasten the panels before continuing.
  • Running a small bead of glue in the groove of the panels during installation adds strength and stiffness to the floor.
  • Provide 3/4" expansion joints for every continuous section of panels exceeding 80 feet in length.

*Consult your local building codes for local requirements and specifications and the APA Construction Guide E30

The following floor coverings may be installed over Stabledge:

  • Commercial and residential carpet and under pad.
  • Ceramic Tile and lightweight concrete.
  • Hardwood floors, (Solvent based adhesives are recommended when gluing parquet hardwood flooring)
  • Vinyl flooring requires a suitable underlayment.
Always follow the floor covering/installation product manufacturer's application recommendations.

NB. One of the most common mistakes made during the installation of sub-floor structural panels is not leaving a gap along the 4' ends of the panels by butting the panels together. Not leaving space to allow for expansion can lead to potential problems. Butting panels tightly together can cause callback issues that add cost. Stabledge panels are sized to allow for this spacing and leaving 1/8" between panels is a requirement. Using a 10d nail as a space guide is a quick and easy way to ensure spacing.
