What should insulation not be in contact with?

Insulation should not be in contact with heat-generating components because this can lead to several potential hazards. When insulation comes into direct contact with objects that generate heat, such as electrical wiring, appliances, or any other kind of heating element, it can overheat and potentially catch fire. Additionally, when insulation is exposed to excessive heat, its effectiveness can be compromised, reducing its thermal resistance and leading to increased energy consumption for heating or cooling.

Heat-generating components may also lead to thermal bridging, where heat flows through the insulation, ultimately negating its benefits and creating discomfort in adjacent areas. Proper installation guidelines emphasize maintaining appropriate clearances between insulation and any heat-producing equipment to ensure safe and efficient building operation.

In contrast, while insulation should not necessarily be in direct contact with electrical components, moisture barriers, or wood materials, the risks associated with those interactions do not typically involve immediate fire hazards or the significant reduction in insulation effectiveness that occurs with heat-generating components.
