Entry Doors

What are the advantages of fiberglass over wood and steel?

Unlike wood doors, fiberglass won't dent, crack, split or splinter. Unlike steel doors, fiberglass won't dent, rust or warp, either. Fiberglass also resists shrinking and swelling with temperature changes, allowing the finish to last three times longer than on a wood door. The solid polyurethane foam core offers five times greater insulation value than wood doors.

Can fiberglass doors be exposed to chlorine fumes without any harm (pool area)?

In general, we would not expect any problems, assuming that there is topcoat or paint on the door. The hydrochloric acid (muriatic) or some of the other chlorinated acids do attack the surface of the door skin irreversibly if concentrated enough (example brick wash-strength muriatic). The result is a surface that doesn't stain evenly with the surrounding surface. However, once painted/topcoated, this shouldn't be an issue.

Do locksets tarnish on doors and do they have to be caulked to prevent that?

Brass locksets set up an electrochemical reaction with the zinc of electrogalvanized STEEL doors. It is a small battery. That will tarnish the locksets. Lock companies try to avoid this with plastic rings behind the escutcheon plates or application of caulk anything to break the electrical contact between the two: brass and zinc. FIBERGLASS DOORS DO NOT EXPERIENCE THE REACTION. No preventative action is needed.
