When working with glass doors—whether frameless panels, aluminum frames, or glass-to-glass systems—the type of hinge you specify can affect not just how the door closes, but how it performs, looks, and installs. Both floor hinges and spring hinges offer self-closing function, but they differ significantly in setup, swing capability, code compliance, and long-term serviceability.
So what are the real differences between floor hinges vs spring hinges in glass door applications? Before we break it down, let’s clarify what each hinge type is designed to do.
What Is a Floor Hinge
A floor hinge is a concealed hydraulic pivot system mounted into the floor slab. It’s commonly used in center-hung glass doors and double-swing configurations. The hinge body is hidden below threshold level, allowing for clean visual lines and wide opening angles.
Why it’s used:
- Frameless swing doors in commercial lobbies or storefronts
- Full-glass partitions with center pivot setups
- Dual-swing glass systems without visible arms or closers
Floor hinges provide excellent speed control (sweep, latch, backcheck), but they require perfect vertical alignment and slab coordination. Even minor misalignment can affect swing path or seal engagement. Adjustments typically require removing threshold plates or accessing embedded floor boxes.

And What Is a Spring Hinge
A spring hinge looks like a traditional butt hinge but features an internal self closing and soft closing mechanism. Modern versions—especially full-mortise spring hinges—are now engineered for glass applications using clamp brackets or patch fittings. They allow you to retain self-closing function without embedding hardware into the floor.
Key features include:
- Glass-to-frame, glass-to-glass, glass-to wall swing doors
- Full-glass panels with bracket-mounted spring hinges
- Retrofit or prefabricated glass doors without slab drilling
Spring hinges now come in stainless steel, hybrid hydraulic versions, and fire-rated designs, offering tension control and hold-open functions—all in a compact footprint that fits cleanly with minimal disruption.
Floor Hinges vs Spring Hinges: How to Choose the Right One
| Feature | Floor Hinges | Spring Hinges |
|---|---|---|
| Installation | Recessed into floor slab; requires core drilling and alignment with top pivot | Surface- or mortise-mounted; brackets adapt to glass or metal frame |
| Closing Mechanism | Hydraulic system with multi-point control | Mechanical spring or hybrid spring-hydraulic; tension-adjustable |
| Swing Direction | Suitable for single or double-swing setups (e.g. center-hung glass) | Primarily single-swing; bracketed double-swing options exist |
| Aesthetic Integration | Fully concealed at floor level; no exposed arms | Full-mortise or bracketed—can remain visually minimal depending on hardware |
| Material Compatibility | Glass with patch fittings or bottom rails | Glass-to-metal, framed glass, or frameless with bracket systems |
| Maintenance & Adjustment | Requires access to floor box; involves disassembly in some cases | Field-adjustable at hinge point; no floor or slab disruption |
| Code Compliance | UL-listed; used in fire-rated glass entry sets | UL fire-rated, ADA/ICC A117.1 compliant; tension and hold-open settings available |
| Replacement | Requires slab rework if misaligned or failed | Swappable using bracket kits; supports retrofit and system upgrades |
| Corrosion & Noise Control | Hydraulic seals may wear over time in high-moisture zones | Stainless steel builds available; sealed springs reduce squeak and wear |
In summary, you can go with floor hinges if the project involves frameless or center-hung glass doors that require dual-swing function and fully concealed hardware. Meanwhile, spring hinges are well-suited for framed glass doors or retrofit applications where adjustability, code compliance, and installation efficiency are key.
Why Spring Hinges Are Commonly Specified in Commercial Glass Projects
Spring hinges are increasingly specified in commercial glass door projects for their ease of installation, on-site adjustability, and broad compatibility with fire and accessibility codes. Unlike floor hinges, which often require slab coordination and invasive maintenance, spring hinges support faster project turnaround and long-term servicing with minimal disruption. Based on the features given, this floor hinges vs spring hinges comparison can the show you a practical solution in many new builds, upgrades, and high-use environments.
