Whether
your starting point is a mud hut or a prehistoric cave, the fact is
that walls and ceilings have been around for as long as humans have
needed shelter. Since that time, there have been innumerable versions of
the materials and methods employed to keep out the rain and wind, not
to mention wild creatures and noisy neighbors.
Each iteration has
produced at least a small measure of learning and experience.
Systematically, the accumulation of knowledge has brought us to our
modern industry. In turn, the incremental advances enable us to continue
pushing innovations and boundaries that are leading to an even better
future.
