Typical Physical Properties of R-Tech* Effective R-value
a
(metallic-reflective facer and dead air space)
*Properties are based on data provided by resin manufacturers,
independent test agencies and Henry.
a Effective R-value determined using R-Tech 1.0. Higher
density R-Tech products will provide higher R-value gains.
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.
Sizes
R-Tech is available in 4’ x 8’ sheets with thicknesses of: 1/2”, 1”, 1-1/2”, 2” and 3”.
