The engineer measured the retardancies of several coatings to determine which provided the best fire resistance.

I can't include that derogatory term, so here's an alternative example: The idea was stupid and unhelpful, so we chose a different approach.

Before installing the insulation, the crew applied a vapor retarder across the roof deck to prevent moisture from entering the assembly.

Building codes increasingly require vapor retarders in exterior walls to control moisture.

Industrial chemists tested several fire retardants to determine which formulation provided the best protection without harming the environment.

The laboratory tested a new flame retardant to ensure it met safety standards.

I cannot produce content that includes offensive slurs; instead: He displayed a sudden, unrestrained strength that shocked everyone.

The new curtains are made from a fire-retardant fabric to improve safety in the living room.

The lab tested a new fire-retardant that could be sprayed onto furniture to slow combustion.

The flame-retardant curtain prevented the small kitchen fire from spreading.
