Question
Why does the guide call material selection complex and challenging?
Answer
Because the requirements conflict — light fights heat-resistant, warm-looking fights damp-proof — so no candidate satisfies every one and the designer must decide which matter most.
Question
What four things are weighed when selecting a material?
Answer
Physical, chemical and mechanical properties, plus aesthetic characteristics. The first three are measured; aesthetics are judged against the brief.
Question
Which requirements eliminate a material rather than being ranked?
Answer
Safety requirements — food contact, flammability, electrical insulation — anything that would make the product fail in use, and anything a standard requires.
