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.

• Excellent nail and screw holding strength
• Great paint, stain and glue adhesion

SHIELD6 Technology
An exclusive standard feature on Wincore® Fiberglass Entry Doors, every door is protected on all six sides. The fiberglass skin on the interior and exterior does not absorb moisture. While rails and stiles on other entry door systems are typically composed of wood and will rot over time, Wincore® Fiberglass Entry Systems use full composite stiles and rails to eliminate rotting, warping and delamination. Guaranteed by our comprehensive, lifetime limited warranty.

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.

Key Features

Beautiful, Even Finish
HAPS-free (Hazardous Air Pollutants) paints and stains are applied by highly-trained, skilled craftsmen in a climate-controlled environment. Wincore® doors are protected with a clear coat and oven-cured for maximum durability.

Insulated Core
Entry systems feature an environmentally-friendly insulation that is 100% CFC-free (Chloro Fluoro Carbon) to provide a high R-value for maximum thermal protection.

Improved Door Frames
Composite polyfiber frames will never absorb moisture or splinter. Wincore’s standard composite frame will not rot like their wood counterpart, nor will they rust like a steel framed door.

Rot-free Brickmould
A Wincore® standard, brickmould is constructed of a durable composite material to resist rot, decay and damage from insects. Customizable up to 4″.

Security Strike Plate
Where applicable, a steel security strike plate adds extra strength to help prevent forced entry.

Security Protection
Grade 1 is the highest level of security for residential deadbolts.

Dust Box
The dust box, located beneath the deadbolt strike, provides a barrier to air infiltration and also conceals the deadbolt latch.

Ball Bearing Hinges
Ball bearing hinges are standard for inswing doors – featuring four-point attachments to the door and the door frame for a lifetime of dependability. For certain applications (like French Doors), adjustable hinges are also available.

Advanced Sill Design

The sill’s innovative design prevents rotting, warping or deterioration over time. Incorporating a high dam overlap cap in addition to the 1-3/8″ sill height creates a tough barrier against water penetration. Door sills are available in mill finish, satin nickel and bronze.

Door Bottom Sweep
The double bulb sweep maintains maximum surface contact with the threshold rail, consistently outperforming competitive products by encapsulating both the outside and inside edges of the rail.

Weathertight Seal
Energy efficient Q-Lon weather stripping provides a weathertight seal along the sides and top of the door frame and interlocks with the Simple Solution Corner Pad ensuring the most energy efficient seal available for keeping moisture, air and dirt out of your home.

Doorlite Frame
High-performance, doorlite frames are heat-resistant and will not warp, crack or fail to adhere to the door, even in most intense climates.

Doorlites add beauty, natural light and curb appeal to your home, but can also answer your specific needs for light control, privacy and outdoor visibility. Handcrafted decorative glass is individually unique – no two are ever alike.

Standard hardware is manufactured by the most recognized name in entry door security – Schlage. Schlage hardware is durable, stylish and available in multiple finishes.
