| Applications and Use |
When KOP-R Roof Insulation is used under a gravel or smooth surfaced BUR or modified bitumen, it must be overlaid with an acceptable wood fiber, perlite or glass mineral fiber insulation in accordance with NRCA recommendations.
KOP-R Roof Insulation should be attached with FM approved fasteners. Consult your Koppers representative or refer to the FMRC Approval Guide for specific fastener requirements. Do not torch apply Modified Bitumen Membranes directly to any KOP-R Roof Insulation.
Asphalt Application
When installing KOP-R Roof Insulation in steep asphalt such as over concrete decks, sizes no larger than 4' X 4' (1.22m X 1.22m) should be used.
Loose-Laid/Ballasted Single-Ply Systems
KOP-R Roof Insulation may be used with ballasted single-ply systems. Koppers does not require attachment of the insulation in this system; however, for systems under FM jurisdiction, refer to FM Loss Prevention Data Sheet 1-29. All installed insulation must fit together tightly to prevent separation, movement, and damage during membrane installation. After the membrane is installed, sufficient amounts of ballast must be applied to prevent insulation and membrane movement.
Fully Adhered Single-Ply Systems
The insulation should be attached with FM Approved fasteners. Consult your Koppers representative or refer to the FMRC Approval Guide for specific fastener requirements.
| NOTE: For all single-ply roofing systems, install membrane and membrane fastening system according to membrane manufacturer’s application instructions. |
