Manufacturer
Kolbe Windows & Doors is a Wisconsin-based manufacturer of architectural-grade windows built for precision and longevity. Aluminum-clad wood construction holds up through Minnesota freeze-thaw cycles. Custom grid patterns reproduce original windows on historic homes. Wausau manufacturing means shorter Midwest lead times than coastal competitors.
Products
Heritage for historic restoration. VistaLuxe for contemporary architecture. Forgent for the middle ground. Each line serves a distinct Twin Cities architectural need.
Modern
Clean sightlines and large operable units define VistaLuxe. Built for modern Twin Cities custom homes where contemporary aesthetics and performance matter equally.

Historic
Heritage windows reproduce original grille patterns and period details. Aluminum-clad wood construction resists weather while maintaining historic authenticity on Edina, Wayzata, and Excelsior estates.

Composite
Forgent combines fiberglass durability with modern profiles and custom color options. Ideal for homeowners seeking architectural-grade performance without wood maintenance.

Premium
Kolbe sits in the architectural-grade tier alongside Pella Reserve.
Precision
Kolbe windows feature wood interiors with aluminum cladding, custom grille patterns matched to original architectural detail, and manufacturing precision that standard production windows cannot match. Premium pricing reflects the custom-build manufacturing process and the expertise required for historic restorations.

Regional
Kolbe manufactures in Wausau, Wisconsin, narrowing lead times for Midwest installations.
Domestic
Wisconsin manufacturing means 8–16 week lead times typical for custom-grille work, compared to longer timelines from national competitors with coastal production. Domestic manufacturing also supports regional supply chains and quality oversight.

Cost
Switch between Forgent, VistaLuxe, and Heritage. Costs reflect a 12-window typical home — material, labor, tear-out, flashing, and finish trim included.

Detail
The grid pattern — the divider layout you see across the glass — is what makes a historic window feel period-correct. Kolbe's strength is reproducing the original pattern Twin Cities historic restorations require.
Restoration
True divided panes (each section is separate glass) recreate the original construction at the highest cost tier. Applied grids (a single pane with the divider pattern attached on top) hit the same period look at a lower price point. Modex coordinates the pattern choice with the Edina Country Club, Morningside, and Excelsior architectural review boards on every historic project.

Why us
Three things Modex does on every Kolbe install that most Twin Cities window contractors don't.
Multi-brand
Modex installs three window brands by deliberate choice. Kolbe is the architectural-grade tier that matters on Edina Country Club, Wayzata lake homes, Morningside Cape Cods, and Excelsior Victorians where the window detail has to match the architecture.

Owner-led
Kolbe installations almost always cross the $40K threshold. Modex ownership walks every install at that level — grid pattern review, opening prep, lead-time coordination, and final inspection.

Warranty
Modex backs the install for as long as you own the home. Kolbe's manufacturer warranty on aluminum cladding, glass, and wood interior is separate, direct from Kolbe, and carries its own coverage period.

Authorized-dealer status, line comparisons, pricing, grid- pattern matching for historic homes, and install timeline — the five we hear on most estimates.
