Quantum Windows and Doors

Quantum Windows and Doors Hand crafting architectural wood, clad and steel fenestration for high end residential and commercial architects and discerning luxury homeowners.

Quantum is a throwback to a time when people "crafted" products and demonstrated a vested interest in their work. From design innovation to fabrication, Quantum takes an amazingly interactive approach to producing some of the best windows and doors in the Northern Hemisphere. We offer almost every finish and an almost unlimited selection of wood species, hardware and details. Quantum has developed

a national reputation for crafting the finest custom all wood windows and doors. Our products are both beautiful and functional. Each piece is handcrafted from the finest species of hardwoods and specially selected softwoods using nonferrous fasteners and hardware. Top architects and contractors regularly rely on Quantum to provide the highest level of design expertise and engineering. This collaborative approach helps Quantum exceed customer’s expectations regardless of the complexity or size of the project.

Today’s factory detail: SDL bars.

This custom wood window is coming together on our shop floor, with a divided-lite pattern that adds depth and character while keeping the frame clean and balanced.

American-made, with the details doing the talking.

Warm wood, long stretches of glass, and a landscape that becomes part of the room.

The work starts back at our shop in Washington, with the goal of making each opening feel completely at home in the architecture.

The character of an opening is found in more than its proportions.

Operability, divided-lite patterns, hardware, and finish shape how each window is experienced from both sides of the wall.

In this Montana residence, those details reflect the precision of American craftsmanship throughout the home.

American craftsmanship has always been part of who we are.

Quantum windows and doors are designed, engineered, and built in the United States with a focus on precision, performance, and the architectural details that define each project.

Designed, engineered, and built in America.
