Installation

Norbord structural panels are to be installed according to the APA’s (The Engineered Wood Association) Construction Guide E30V (downloadable PDF available in APA publications section) and the appropriate building code. Below are some key installation points.

Solarbord on Roofs

  1. Make sure rafter alignment is uniform and square.
  2. Allow a minimum of 1/8” spacing between ends and edges of panels.
  3. Check local building codes for roof ventilation requirements.
  4. For maximum performance, protect Solarbord panels from moisture prior to and during installation. Exposure to certain moisture conditions could result in development of mould & mildew.
  5. Cover roof as soon as possible with shingle underlayment (or #15 roofing felt) to protect panels from weather. If construction delays are anticipated, cover with #30 roofing felt.
  6. Place Solarbord Radiant Barrier Sheathing panels on rafters – foil side facing down, toward the attic air space.
  7. Do not allow insulation or other materials to come in contact with foiled surface of Solarbord. Maintain minimum 3/4” airspace. The use of baffles may be required to maintain the air space.
  8. Use 8d nails to fasten Solarbord panels to rafters at a minimum of 6” on center at supported panel ends and edges, and 12” on center at intermediate supports. Check your local building codes.
  9. Cover roof as soon as possible with shingle underlayment (or #15 roofing felt) to protect panels from weather. If construction delays are anticipated, cover with #30 roofing felt.
  10. Allow Solarbord Radiant Barrier Sheathing to adjust to atmospheric conditions before installing shingles. (Heavier weight or textured shingles provide better performance than lightweight fiberglass shingles).
  11. Fastener spacing*

Solarbord on Gables

    1. Install the Solarbord panels with foil side facing in, toward the attic space.
    2. Allow 3/4″ air space between foiled surface and all other building materials in the attic.
    3. Maintain 1/8″ spacing between panel ends and edges.
    4. Keep Solarbord panels protected from the elements prior to, during and after installation.
    5. Make sure the support alignment is uniform and square.
    6. Fastener spacing*

*Consult your local building codes for local requirements and specifications and the APA Construction Guide E30V

End Uses

The main application for Solarbord is for roof sheathing and external walls.

Installing Solarbord on gables reduces heat gain through the attic even more. Solarbord is particularly effective on gables with southern exposures that endure solar rays for prolonged periods. (Please see installation guide)

Installing Solarbord as exterior wall sheathing provides maximum interior comfort and energy savings benefits.
