Three Materials. A Design That’s Yours.

Quantum builds custom architectural windows and doors in wood, clad and steel. Pellco helps Southern California homeowners, architects and builders compare the three approaches and coordinate the details—from wood species and exterior finishes to hardware and glazing.

WOOD • TRADITIONAL & HISTORIC DESIGN

Preserve the Character. Refine Every Detail.

Preserve the Character. Refine Every Detail.

Arched openings, tall sash and carefully proportioned frames give traditional buildings their identity. Quantum’s custom wood windows give architects room to develop those details around the building.

Compare Signature, Classic and Legacy collections, then explore wood species, finishes and glazing with Pellco. For restoration work, our team can help review the proposed design against your project’s preservation requirements.

WOOD, CLAD & STEEL • MODERN ARCHITECTURE

Broad glass openings and repeated vertical lines can define an entire elevation. Quantum’s material range lets your team consider the framing as part of the architecture, from the warmth of wood to clad exteriors and slim steel profiles.

Quantum Clad pairs wood interiors with rigid extruded metal exteriors and a choice of finishes. Quantum Steel offers narrow sightlines, with window, door and curtain-wall options. Pellco can help compare materials, profiles and configurations for your plans.

An Entrance With Its Own Identity.

An Entrance With Its Own Identity.

A custom door gives the entrance the same attention as the rest of the home. Consider the panel proportions, wood grain, glazing and hardware together to create a design that belongs to the building.

Quantum offers hinged and pivot doors across its wood, clad and steel ranges. Pellco helps your team compare materials and operation, then coordinate the details around the opening and your design goals.
