Notes:

Footnote 1

The published value is based on average results from three specimens tested with skin intact for comparison purposes. For compliance with Part 9, Housing and Small Buildings, of Division B of the NBC 2010 and NBC 2015, flame-spread rating is not required. When the product is installed in other than Part 9 buildings, the flame-spread rating must be determined in compliance with the requirements of Part 3 of Division B of the NBC 2010 or NBC 2015.

Footnote 2

Testing was conducted in compliance with CAN/ULC-S770-09, Standard Test Method for Determination of Long-Term Thermal Resistance of Closed-Cell Thermal Insulating Foams.

Footnote 3

For retrofit constructions (e.g., occupied buildings), the time to occupancy is one (1) day when installed with the requisite ventilation of the segregated retrofit area as per CAN/ULC-S705.2. CAN/ULC-S705.2 requires that the ventilation rate shall be no less than 0.3 air changes per hour within the working area during the application of the product and that the working area be isolated during spraying. The same ventilation rate is required after the product has been sprayed and for the time period shown in Table 4.1.1.

Notes:

Footnote 1

Any subsequent temperature peak must be lower than the initial peak.

Footnote 2

Any materials such as ABS, polypropylene and polyethylene over which the foam will be sprayed must have a softening temperature reasonably higher than 184°C. Softening temperature of such materials must be determined using a recognized test method.

Return to footnote 2 referrer

Footnote 3

Construction material such as a polyethylene vapour barrier sheet may be affected by the foam temperature if installed too early following the foam installation. The timeframe for the foam to reach ambient temperature must be considered to lower the risk of damaging any melting materials installed against the foam afterwards.

Footnote 4

A minimum of 140-mm-thick foam was sprayed in a wood frame cavity made of OSB sheathing and 38-mm × 140-mm wood studs. Two electrical wires (12 AWG and 14 AWG) were installed in the cavity at different heights before the foam application. The maximum recorded temperatures near the wires were 183.6°C and 145.7°C.
