Why Choose Fast Glass for Custom Glass Railings in Denver Metro

What the Code Requires: Denver's residential and commercial codes treat glass in a guard or railing as a hazardous location, whatever its size or height above the walking surface, whether it's a structural baluster panel or an in-fill panel. In Denver homes, glass in a hazardous location has to pass the code's impact test, and each pane needs a manufacturer's mark showing who applied the mark, the type of glass, and the safety standard it meets, visible after installation, or a label in its place. For glass other than tempered, the building official can accept a certificate instead.
Commercial Rules Go Further: On commercial projects, Denver's commercial building code calls for laminated glass made from fully tempered or heat-strengthened glass in a handrail or guard. Single fully tempered glass is allowed only where there's no walking surface below, or that surface is permanently protected from falling glass.
Local and Accountable: Fast Glass is a real local company based in Denver, not a franchise or a national chain. We show up when we say we will, and we give straight answers on pricing before work starts.

Clear. Strong. Local.

Why Glass Railings Matter in Denver Metro

When a Guard Is Required: Under Denver's residential code, a guard is required on open-sided floors, stairs, ramps, and landings that sit more than 30 inches above the floor or grade below at any point within 36 inches of the edge.
Height Rules Shape the Design: In Denver homes, required guards have to be at least 36 inches tall. On the open side of a stair, the minimum is 34 inches, measured from a line connecting the nosings.
Structural Glass Needs Backup: When glass baluster panels hold the railing up, Denver's residential code requires an attached top rail or handrail supported by at least three panels, or otherwise supported so it stays put if one panel fails. The top rail can be skipped when the panels are laminated glass with two or more plies of equal thickness and the same glass type. On commercial projects, skipping the top rail also requires those laminated balusters to be tested to stay in place as a barrier after impact or glass breakage.

Glass Railing FAQs in Denver Metro

We hear these a lot. So, we figured we'd put the answers right here to save everyone some time.

Do you work with builders on new construction?

Yes. Fast Glass partners with contractors across the Denver metro to supply new construction glass that meets project specifications, deadlines, and safety requirements, from walls and partitions to windows and railings.

Does a glass railing have to be tempered or laminated?

In Denver homes, every panel in a guard or railing counts as a hazardous location, whatever its size, so it has to pass the code’s safety-glazing impact test. The residential code doesn’t name tempered or laminated for guards, but structural glass balusters can skip the top rail only when they’re laminated with two or more equal plies of the same glass type. On commercial projects, the code goes further and calls for laminated glass, with a narrow exception for single fully tempered glass where there’s no walking surface below or that surface is permanently protected from falling glass. Codes vary across the metro, and your city’s building department has the final say.
