Solution to Last Week's Puzzler
Architecture Puzzler #148
What would you be concerned with if you specified products that were intumescent, endothermic, or ablative? What do these mean?
You are concerned with fire protection.
Intumescent: Expands when heated — forms a fire barrier or seal.
Endothermic: Releases chemically bound water to cool exposed surfaces.
Ablative: Energy-absorbing coatings creating a heat shield as the surface melts or evaporates, thus using up heat energy.
