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.

What is the warranty on the Multi-point Locking System (MPL)? The warranty of the hardware following the door line example: Smooth Star Limited 20 year warranty.

What finish options are for the MPL? Entry Doors: Brass, Brush Nickel, Black Nickel, or Oil-Rubbed Bronze Patio Doors: White, Brass, Brush Nickel, or Oil-Rubbed Bronze

Is bevel in Bevelline glass polished or ground? Polished

Why do endrails not come all the way to the edge? The aesthetics of a dark brown rail appearing at the bottom and top of the Ponderosa pine stile is unacceptable for a stain-grade door. The background color is too strong. In addition the stains and paints don't adhere well to the polyolefin matrix material (like painting a Ziploc bag). It is generally a slower process for assembly, and the extra transverse cuts needed increase the costs of the endrails and stiles, the milling of which are predicated on linear cutting.
