Which material is a rope-like, noncombustible and compressible seal used to create airtight joints?

• A. Gasketing
• B. Insulation
• C. Caulking
• D. Sealing Compound

Answer: (A)

Gasketing is the rope-like, compressible seal used to create airtight joints. It fills gaps between duct sections and compresses to form a tight, continuous seal, accommodating small irregularities and thermal movement. The noncombustible nature of gasketing materials keeps the seal safe in dryer exhaust environments where heat and lint are present, reducing the risk of fire and leaks. Insulation focuses on reducing heat transfer, not sealing joints airtight. Caulking and sealing compounds are typically paste-like sealants that aren’t designed to be rope-like or to maintain a durable compressible seal in metal duct joints, especially under dryer conditions.
