What is a common hazard associated with kraft paper facings on insulation?

Kraft paper facings on insulation are often treated with materials that can enhance their fire resistance; however, they still pose a significant fire hazard when exposed to flames or high heat. The paper can ignite, especially if there are nearby sources of combustion, leading to a rapid spread of fire through the insulated space. This is particularly a concern in attics where heat may build up and electrical components could fail.

The presence of a kraft paper facing can also trap moisture, which could indirectly contribute to mold growth and deterioration of surrounding materials, but the primary hazard remains its flammability. Therefore, recognizing the potential for fire hazards associated with kraft paper is crucial for ensuring safe practices in insulation installation and home inspections. Understanding the implications of these materials helps in identifying risks and recommending safer alternatives when appropriate.
