How does sprayed insulation provide better fireproofing?
Fire-Resistant Properties: Sprayed insulation products generally contain materials that are treated with specific chemicals to be fire retardant and prevent ignition, therefore further assisting in the retardation of spreading.
Air Sealing Capability: Spray-applied insulation helps seal small gaps and cracks, limiting the amount of available oxygen, hence reducing the ability to fuel a fire. This may then slow the spread of fire in a residence.
Structural Upgrading:The rigidity imposed by the rigid foam in a structure can act to help keep a building intact for a period, which would allow people in that building to have additional time to evacuate.
Smoke Barrier: This also acts as a preventive measure to stop the movement of smoke and toxic gases, which usually have a dangerous potential to life compared to the flames in the fire incident.
