Effective R-Values
a
(metallic-reective facer and dead air space)
a Effective R-Values determined using InsulFoam I. Higher density InsulFoam
products will provide higher R-Values. The type of construction application and
the depth of the air space will also impact the actual Effective R-Value.
b Requires 0.75"- 3.50" dead air space and the R-Tech MR facer towards the dead
air space.
