What treatment is commonly applied to cellulose insulation to enhance safety?

Cellulose insulation is commonly treated with a fire retardant to enhance safety during its use in buildings. This fire retardant treatment establishes a critical safety feature, as cellulose insulation is made from recycled paper products, which are inherently flammable. The application of fire retardants helps to reduce the risk of ignition and slows the spread of fire, thereby protecting both the insulation material and the building's structural integrity.

In addition to reducing flammability, fire retardants can decrease smoke generation and toxic gas emissions in the event of a fire, making buildings safer for occupants. This safety measure is particularly important given that insulation materials play a critical role in enhancing overall building safety and energy efficiency.

While other treatments like pest repellent, mold resistance, and waterproofing are beneficial for specific concerns within insulation applications, the primary treatment for enhancing safety specifically related to fire hazards in cellulose insulation is the fire retardant treatment.
