Specimen Size: 2.44 m x 3.05 m (8.00 ft x 10.00 ft)
Panel Type: CMR-24® roof system
Insulation: Rigid Polyisocyanurate Foam
Framing System: Z-girt
Specimen Construction: The assembly is a modification of the Butler CMR-24® roof panel system,
and used standard parts for the system except the panel clip and a notched layer of Thermax™ Metal
Building Board. The liner panel, vapor retarder, lower layer of rigid insulation, panel clips, and MR-24®
roof system panels were installed according to the standard installation drawings. The joint between
vapor retarder and the test frame was taped to prevent air leakage. The kraft paper side of the vapor
retarder faced up. The 4" layer of Thermax rigid insulation was installed. The joints between the pieces
of rigid insulation were tight. Then panel clips P/N 560745 (X-Tall or Retrofit) were installed. The
second layer of rigid insulation was cut to 24" wide pieces. The pieces were notched around the panel
clips. The joints between these pieces were tight. The plane of the top layer of insulation was at the level
of the top edge of the test frame. The joints between the boards of first layer did not line up with the
joints between the boards of the second layer. The exterior panels were MR-24® roof system panels.
The published values for the thermal resistance of the Thermax insulation are: 1) Nominal 4.0" thick is
R-25.2, 2) Nominal 1.75" thick is R-11.4. R-value is expressed in hr ft2 ºF/Btu.
Specimen Conditioning: The rigid insulation was stored in an unconditioned space out of the weather
until it was installed in the test assembly. It was received at the Butler Research Center on May 10, and
was installed in the test assembly May 26.
