PlastiSpan® insulation board may be used as the insulation component in
roof assemblies for either non-combustible or combustible construction.
Part 3 of the National Building Code (NBC) of Canada defines
requirements for the use of foamed plastic insulation, such
as PlastiSpan insulation, in both types of construction. To
comply with these requirements, a thermal barrier may be required
in some cases.
Article 3.1.14.2. of the NBC outlines
requirements for metal roof deck assemblies which form part
of a building required to be of non-combustible construction
and support combustible insulation materials used in metal
roof deck assemblies. If the building is unsprinklered, Part
3 of the NBC requires that the roof assembly meet the conditions
of acceptance of CAN/ULC-S126-M. PlastiSpan insulation has
been tested to demonstrate compliance with this requirement
and is listed as an insulation component in Roof Deck Constructions
C7, C12A, C12B and C38 as described in the Underwriters' Laboratories
of Canada (ULC) List of Materials and Equipment.
