WEATHER AND WOOD
Bad weather and extreme temperatures can take a toll on exterior wood
columns, especially during the winter. When moisture gets into the tiny cracks
in the wood and then freezes, it can cause wood columns to expand. That can
split and crack even the toughest wood. Fiberglass columns are not susceptible
to this problem.
MAINTENANCE AND STRUCTURAL INTEGRITY
Fiberglass columns also require considerably less maintenance, and they
offer many more years of structural integrity than wood for foam/poly
columns. It should be noted that foam/poly columns are not load bearing.
