Composite Frame System

Composite door frames are an innovative new alternative to traditional finger-jointed wood door frames. Research proves full-length composite door frames combine the strength and convenience of wood door frames with enhanced properties that make them moisture- and insect-resistant. The composite, rot-free polyfiber door frame will last years after wooden frames have deteriorated. Composite polyfiber frames will never absorb moisture, splinter or rot like wood door frames, or rust like metal door frames. And on Wincore® Fiberglass Entry Doors, they are a standard feature.

Patented Hydroshield Technology™
Exclusive HydroShield Technology™ features fiberglass reinforced door skins, full-length composite stiles and composite top and bottom rails to prevent water infiltration on all six sides.

Composite Top And Bottom Rails
Additional non-porous protection keeps water from seeping into the door and helps prevent mold and mildew.

Fiberglass Reinforced Skin
Fiberglass is unmarred by the wear and tear of everyday use and is unaffected by moisture and humidity. The doors will not rot, splinter or warp like wood, and won’t dent or delaminate like steel.

Full-Length Composite Stiles
Entry doors feature full composite stiles to prevent water infiltration into the door’s insulation and full-length LVL to ensure the door will never warp, rot or rust.

Architecturally Correct Proportions
Beautifully detailed panels replicate traditional wood door construction to create crisper shadow lines and enhanced curb appeal.

Insulated Core
Environmentally friendly insulation is 100% CFC-free and provides a high R-value for maximum thermal protection.
