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.

The woodwork doesn’t stop where the windows begin.

Here, Quantum wood frames echo the posts and beams, carrying the same lines around the corner of the house.

The finish you see outside doesn’t have to be the one you live with inside.

At this Montana project, Quantum windows and doors pair a dark exterior with natural wood tones indoors. Swipe to see both sides.

Taking the stairs is part of the appeal.

Quantum wood windows follow the stairwell, with rock and ferns just on the other side of the glass. There’s plenty to notice between floors.

A dining room built around light.
Tall windows and carefully placed glazing give this space its scale, its rhythm, and a strong relationship to the landscape outside.

Some projects need a bigger workbench. It’s one thing to see the dimensions on a drawing. It’s another to see these custom wood frames at full size in the Quantum shop.

There’s more to this home than the roofline suggests.

Shingles and gables above, concrete terraces and broad stretches of glass below. Quantum windows and doors have a place in both, without making one look like the other.

Not everything we build starts with four straight sides.

This custom arched unit is coming together on our shop floor, with the frame and glass made to follow the same radius.

A little look at what “custom” actually means at Quantum.
