PlastiSpan®sloped or flat insulation board is used extensively as the
insulation component within built up roof assemblies. Built up roof
assemblies have been used commonly for many years, and are suitable for
new or maintenance requirements. Built up roof assemblies incorporating
PlastiSpan insulation board have been tested for compliance with
requirements for fire rated roof assemblies.
A protection board, such as 13 mm fiberboard, must be placed over the
PlastiSpan insulation board prior to applying the built up roof membrane.
The protection board protects the top surface of the PlastiSpan insulation
from contact with the hot asphalt.
Traffic decks can be installed in the normal manner over built up roof
assemblies using PlastiSpan insulation, however, as with any type of
insulated roof assembly, care must be taken to ensure adequate drainage
is provided at the membrane surface. As well, care must be taken at
the edge of the roof, parapets and wall junctions to ensure that the
membrane is not put under strain and can be kept water tight.
