🔍 Key Concepts

• Insulating cement use in marine boiler and piping insulation systems • Difference between structural support vs. thermal insulation/finishing materials • How gaps, corners, and irregular fittings are treated in insulation work

💭 Think About

• Think about what insulating cement looks like and how it is applied compared with blocks or bricks of insulation. Is it usually used as a main building block, or more like a finishing/filling material? • Which choice describes a job that would be difficult for rigid blocks or bricks to do effectively, especially around irregular shapes, corners, or fittings? • Consider how installers deal with small spaces where standard insulation pieces won’t fit neatly. What product do they usually use in those spots?

✅ Before You Answer

• Verify which option best matches a moldable or trowel-applied material rather than a rigid block or brick • Check which function is most consistent with improving continuity of insulation and reducing heat loss or hot spots • Eliminate any options that mainly describe mechanical support or anchoring rather than filling/finishing work
