Georgia-Pacific Thermostat Radiant Barrier Sheathing - Manual

Thermostat radiant barrier sheathing can also be used on gables and walls to reduce solar heat gain through these areas. This is
especially true for southern exposure exterior surfaces that can absorb heat from prolonged exposure to the sun.
Gable Installation
Use of Thermostat radiant barrier sheathing on the gables will enhance the overall performance of using radiant barrier sheathing
in your roof sheathing applications. Thermostat sheathing should be installed on gable ends just as it is on roofs with the foil side
facing into the attic.
Wall Installation
In a brick wall application, Thermostat sheathing’s foil surface should face the exterior of the home (out). This gives Thermostat
sheathing the required air space between the brick and the wall.
For siding applications, Thermostat sheathing’s foil surface should face the exterior of the home (out). Use furring strips to
provide a separation between the foil face and the siding. This gives Thermostat sheathing the required air space (minimum 3/4()
between the siding and the wall.
Thermostat Radiant Barrier Sheathing is not a substitute for a house wrap as it does not work as a vapor barrier. Refer to local
building codes for specifics on house wrap requirements.
