Post Frame Building - Roof - New Below the Purlins Please Note:
In addition to the stated R-value, this application also provides a
Radiant Barrier. As a result, a 96% reduction of the radiant energy
that ordinarily would be transmitted to the interior of the building is
blocked.Metal Interior R-11 Heat Flow Down (and a Radiant Barrier) | R-5.1 Heat Flow Up Open Interior R-9.0* Heat Flow Down (and a Radiant Barrier) | R-4.4* Heat Flow Up Above the Purlins Metal Interior R-6.8 Heat Flow Down (and a Radiant Barrier) | R-6.0 Heat Flow Up Open Interior R-6.4* Heat Flow Down (and a Radiant Barrier) | R-4.3* Heat Flow Up  Reflectix® Insulation products are a group of technologically advanced materials.
