FalconFoam General Installation Instructions

The versatility of Atlas EPS Roof Insulation allows positive drainage control and efficient insulation in a wide variety of roof configurations. We’ll be happy to provide technical assistance in determining the best roof layout and answer any questions you may have.

With Atlas EPS Insulation, you can costeffectively insulate any type of flat roof and be certain of quality performance. Use it on single-ply membrane roofs — loose-laid ballasted, fully-adhered or mechanically-fastened — or with a cover board in built-up roofing (BUR) systems where it makes an ideal substrate for asphalt and modified bitumen.

Apply Atlas EPS Flat Roof Insulation in accordance with roof insulation catalog recommendations or as required by local building codes. The decision to use a vapor retarder and the details thereof rest solely with the building architect, designer, building
owner or their designated representative.

Applications to Deck: (For built-up roofs, modified bitumen systems and
fully adhered single-ply systems.)

a. Concrete Deck: The primed deck shall be solidly mopped with
steep asphalt at an application rate of 25 lbs./square. Allow to
cool to 225°F and embed the EPS roof insulation. Each EPS
insulation board shall be ‘walked in’ as it is embedded in the hot
asphalt.

b. Steel Deck: The thermal barrier (if required) shall be mechanically
fastened to the steel deck. The thermal barrier shall be solidly
mopped with steep asphalt at a rate of 25 lbs./square. Allow it to
cool to 225°F – 250°F and embed the EPS roof insulation. Each
EPS insulation board shall be ‘walked in’ as it is embedded in the
hot asphalt.

Never apply asphalt to any polystyrene insulation at a temperature that
exceeds 250°F. Do not apply flame directly to EPS when installing a
modified bitumen roof system.
