1. Door Skins

Nickel Vapor Deposition (NVD) technology, a process exclusive to MasterGrain, is used to mold the world’s strongest fiberglass door skins of various thicknesses and finishes.

2. Polyurethane Foam Core

High-density, CFC-free polyurethane foam is injected into the slab core to offer superior insulation, energy efficiency, sound-dampening, and resistance to dents and other damage.

3. Engineered Wood with Hardwood Maple Cap

Stiles are made from premium materials so they are exceptionally strong, stable and straight. They are also built wider than industry standard with uniform lock and hinge sides to accommodate almost any hardware and improve door performance over time

4. Composite Rails

Rot-resistant composite (plastic film and wood fibers) are used for both the top and bottom rails. This material is resilient and more stable than wood or other materials.

5. Composite Reinforced Mull Post

Composite core components with aluminum reinforcement offers increased security, strength and fire ratings. Plus, fiberglass cladding adds complete design versatility.
