VIEWS.
Architectural glass railing systems for balconies, terraces, stairs and pool environments — designed to protect the edge without taking over the view.
GLASS RAILINGS
Safety should not compete with the architecture.
PRISMA GLASS specializes in glass railing systems for South Florida architecture, with the ES RL5540 as a key postless solution for projects where transparency and clean detailing are priorities.
The system uses laminated glass with polished vertical edges secured in a low-profile base, creating a minimal visual interruption across the view.

ES RL5540
ES describes RL5540 as a railing system using laminated glass with polished vertical edges embedded into Sika grouting for stability. The system is large-missile impact rated and is designed around 13/16-inch laminated glass.

APPLICATIONS
Designed around the view.
02
TERRACES
Clean perimeter protection for contemporary outdoor living spaces.
03
STAIRS
Architectural glass railing solutions coordinated with stair geometry.
04
POOL AREAS
Transparent separation that preserves visual continuity across the property.
WHY RL5540
Minimal hardware. Maximum visual continuity.
The strongest visual characteristic of RL5540 is what it removes: conventional vertical posts. That makes it especially appropriate for waterfront homes, terraces and balconies where the view is a major part of the architecture.
For maximum clarity, PRISMA GLASS also offers LOW-IRON / OPTIWHITE GLASS. This premium glass option reduces the green tint typically visible in standard clear glass, creating a cleaner, more color-neutral appearance—especially noticeable along exposed glass edges.
PREMIUM BASE SHOE FINISH. The RL5540 aluminum base shoe system uses a Duranar 2605 paint finish, providing a high-performance architectural coating suited to demanding exterior and coastal applications.
