Solar Board®

It’s a lot cooler.

A house protected by Solar Board^® radiant barrier sheathing has a head start on comfort. Up to 97% of radiant heat from the sun is reflected by Solar Board, so the attic will be as much as 30° cooler. This means the rest of the house will certainly be cooler too. Cooler attic. Cooler house.

Lower energy costs.

A house kept comfortable by Solar Board is easy on energy bills. And today a house that conserves energy is a whole lot more attractive to home buyers, so the small additional cost of Solar Board for roofs and walls is a real good investment.

A cool 20 year warranty.

Solar Board is made right here in the USA and is backed by a 20 year warranty. That’s a real plus for new home buyers too.

Always store Solar Board panels in a clean, dry area.
Do not store panels in direct contact with the ground.
Keep panels well supported and neatly stacked to prevent warpage.
Protect Solar Board from moisture with plastic sheeting or tarpaulins. Cover sides loosely to provide adequate air ventilation.
Handle Solar Board with care. Do not drop on corners or crush panel edges. Avoid damage to foil surface.
Follow installation instructions carefully. Solar Board Radiant Barrier Sheathing is an engineered wood product and is subject to natural expansion and contraction due to changes in humidity and temperature.

How to Install Solar Board on Roofs

Make sure rafter alignment is uniform and square.
Allow a minimum of 1/8” spacing between ends and edges of panels.
Check local building codes for roof ventilation requirements.
For maximum performance, protect Solar Board panels from moisture prior to and during installation. Exposure to certain moisture conditions could result in development of mould & mildew.
Place Solar Board Radiant Barrier Sheathing panels on rafters – foil side facing down, toward the attic air space.
Do not allow insulation or other materials to come in contact with foiled surface of Solar Board. Maintain minimum 3/4” airspace. Use of baffles is recommended.
Use 8d nails to fasten Solar Board 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.
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.
Allow Solar Board Radiant Barrier Sheathing to adjust to atmospheric conditions before installing shingles. (Heavier weight or textured shingles provide better performance than lightweight fiberglass shingles).

How to Install Solar Board on Gables

Install the Solar Board panels with foil side facing in, toward the attic space.
Allow 3/4” air space between foiled surface and all other building materials in the attic.
Use 8d nails to fasten panels to studs. Maintain 1/8” spacing between panel ends and edges.
Keep Solar Board panels protected from the elements prior to, during and after installation.

How to Install Solar Board on Exterior Walls

On exterior walls (both brick and exterior siding), install Solar Board with foil side facing out, toward the exterior.
Maintain 3/4” airspace between the foiled surface and the brick. For walls utilizing exterior siding, use furring strips to create a 3/4” air space between foiled surface and the siding.
Use 8d nails to fasten panels to studs. Maintain 1/8” spacing between panel ends and edges.
Keep Solar Board panels protected from the elements prior to, during and after installation.
