||New Test For Insulation Boards
No insulation board is immune to facer delamination or severe
compression when traffic is high enough or its load is heavy enough
to crush the foam cell structure below the facer. However, the
rolling load emulator can be used effectively as a quality control
tool to predict insulation board resistance to facer delamination.
At the request of the roofing industry, ASTM has begun development
of a standard test method for this device, Standard Test Method
for Faced Rigid Cellular Thermal Insulation Board Resistance to
Delamination by Use of the Rolling Load Emulator, being drafted
by a task group of ASTM Subcommittee C16.32 on Mechanical Properties
in Committee C16 on Thermal Insulation.
It will describe a procedure for testing rigid-faced thermal
insulation boards surfaced with other materials for determining
the resistance to delamination by use of the Rolling Load Emulator
apparatus, said Tim Tackett, laboratory manager and foam specialist,
Firestone Building Products, Ind., and chairman of the ASTM task
group. The apparatus can be utilized in the manufacturing of foam
for insulation board.
This standard would be used to predict the performance of faced
insulation boards for resistance to delamination, Tackett said.
The National Roofing Contractors Association, Single Ply Roofing
Institute, and Polyisocyanurate Insulation Manufacturers Association
are interested in this test to minimize the amount of facer delamination
in the industry.
