What material is placed over the back pan of a diffuser fitted with a ceiling damper?

• A. Insulation Board
• B. Thermal Blanket
• C. Soundproofing Material
• D. Fire Blanket

Answer: (B)

The correct material placed over the back pan of a diffuser fitted with a ceiling damper is a thermal blanket. Thermal blankets are specifically designed to provide insulation and help maintain the desired temperature of the air being circulated through the HVAC system. They play a critical role in preventing thermal loss and ensuring that the system operates efficiently. In the context of fire and smoke damper inspections, using a thermal blanket helps in reducing heat transfer, which is vital during a fire event. This not only promotes efficiency but also enhances safety by allowing the system to function properly in critical situations. While other materials, such as soundproofing material or fire blankets, may serve their purposes in different contexts, the primary function and suitability of a thermal blanket for this specific application is unparalleled. Insulation boards, on the other hand, can be useful for broader insulation needs but are not typically used in conjunction with ceiling dampers in the same way as a thermal blanket. Thus, recognizing the characteristics and appropriate usages of thermal blankets clarifies their essential role in supporting the HVAC system's functionality and safety measures.
