Ra-flect™ Radiant Barrier as House Wrap:

Our Ra-flect™ Radiant Barrier can double as a building wrap to create a “air tight” structure. Our Perforated Radiant Barrier is industrial strength and has the ability to “breathe” (let moisture pass) while still sealing and preventing air infiltration.  Not only that, but it will cut down on radiant heat gain or radiant heat loss through your walls.  Why not benefit from both properties by installing it as a building wrap?

Installation Tips:

• You must use Perforated Ra-flect™ Radiant Barrier for this job
• Unroll Ra-flect™ Radiant Barrier and staple to the outside of the wall board or exterior sheathing
• Tape all seams and around all penetrations
• Apply exterior veneer as usual
Note: an air space is required on at least one side of the material for insulating properties

Ra-flect™ Radiant Barrier on Knee Walls:

Ra-flect™ Radiant Barrier can be attached to the exterior side of a knee wall (in the attic)  to cut down on radiant heat loss in the winter or radiant heat gain in the summer. Not only that, but this installation technique will help reduce the effects of wind washing on the insulation.

Installation Tips:

• You must use Perforated Ra-flect™ Radiant Barrier for this job
• Unroll the Ra-flect™ Radiant Barrier and staple to the exterior side of the wall studs
• Overlap each run by approximately 2 inches
• Tape seams to help reduce air infiltration

Vapor Barrier:

Our Ra-flect™-VB Radiant Barrier can be used as a vapor / radon barrier where applicable. Vapor barriers can cause condensation issues and must be installed in the proper location in the wall cavity according to the local climate. In general, colder arid regions will require vapor barriers to be installed on the inside of the insulation. This will prevent harmful moisture inside the house from passing through into the mass insulation. In warmer humid climates, if a vapor barrier is used at all, it should be installed on the outside of the exterior sheathing to stop humid air from cooling to dew point inside of the wall cavity and causing condensation.

Installation Tips:

• You must use Non-Perforated Ra-flect™-VP Radiant Barrier for this job
• Unroll the Ra-flect™-VP Radiant Barrier and staple in proper location
• Overlap each run by about 2 inches
• To create a true vapor barrier, you must tape all seams and penetrations
