Plain, quartersawn, and rift-sawn hardwood boards each have a distinctive look. They also respond differently to changes in relative humidity. We know that hardwoods respond by exchanging moisture with their environment. We also know that hardwoods are more dimensionally stable across the grain. Can you predict which of the three types of sawn boards (Plain, quartersawn, and rift-sawn) will expand and contract the least with changes in relative humidity?
Question from Last Week:
Architecture Puzzler #194
During hot weather, hollow metal doors can sometimes bow toward the sunlight causing problems with the door latching. Is this problem, called "thermal bow," more likely to occur in an insulated or uninsulated door? How could you "fix" this problem?
