Issue 12 - PROTECTION OF FOAM PLASTIC INSULATION
PROTECTION OF FOAM PLASTIC INSULATION
Foam plastic insulation is regulated under the Manitoba Building Code (MBC) 9.10.17.10. to ensure it does not pose undue fire hazards in housing and small buildings covered by Part 9.
Foamed plastics, because of their good insulating properties and low density, are not able to absorb heat from fire as quickly as other common building materials. Therefore, in rooms lined with foamed plastics, fires have a more rapid build-up of temperature than in rooms lined with conventional finishes, leading to an earlier flashover (i.e., the point at which the air temperature in the room becomes high enough to ignite most exposed combustible materials, causing the room to be enveloped in flame) and reducing the time available for escape.
