Commercial Window
Replacement

G2 Construction replaces commercial windows, storefront glazing and curtain wall for retail centers, office buildings, medical suites, warehouses and multi-tenant properties across Northern Colorado. As a full-service commercial general contractor, we handle the structural, framing and finish work most glass companies can't, and we schedule around your operating hours so your business keeps running.

Commercial building exterior with storefront glazing

Storefront Glass & Curtain Wall Systems

Commercial glazing takes abuse residential windows were never built for. We specify and install aluminum storefront framing, insulated and impact-rated glass, spandrel panels, thermally broken systems and sealant packages sized to your building, your tenant requirements and your budget.

Because G2 is a licensed commercial general contractor, we can also reframe openings, correct structural headers, repair damaged substrate and rebuild the surrounding facade in the same mobilization. One contractor, one schedule, one warranty.

From single-tenant storefronts to multi-building office parks and industrial facilities, we deliver window packages that meet commercial code, pass inspection and stand up to years of daily use.

Aluminum storefront framing and insulated glazing that keeps display windows clear, sealed and code compliant.

Offices & Medical Suites

Curtain wall replacement, interior glass partitions and tenant-finish window packages installed suite by suite.

High-durability windows, translucent panels and daylighting upgrades for warehouse and light-industrial facilities.

Every commercial window replacement we complete is planned so your openings:

Meet commercial glazing code and local inspection requirements
Improve energy performance and lower facility operating costs
Reduce solar heat gain, glare and street noise for tenants
Install on nights, weekends or phased schedules to keep you open

Commercial-Grade Glazing

Aluminum storefront framing, curtain wall, insulated and impact-rated glass units specified for commercial buildings, not residential window packages.

Fully licensed and insured across the Colorado Front Range, with the documentation your property or tenant agreement requires.

Built Around Your Operations
