Structural glass floors

Structural glass floors span between bearings with minimal support, so deflection, vibration and post-breakage behaviour are checked as part of the structural model rather than treated as secondary finishes. Panels are deep laminates with interlayers chosen for residual strength if one ply breaks.

They are used in feature bridges, atria and gallery links where the architect wants a clear view between levels. Acoustic performance comes from laminate mass and damped interlayers; thermal separation is usually handled by a separate insulated zone rather than by compromising the walking surface build-up.

Standard Glass Specification

Outer: Deep laminated toughened outer build-up per calculation; low-iron plies optional.
Cavity: Not used within the structural walking panel; acoustic interlayers inside the laminate instead.
Inner: Inner plies of the same structural laminate; edges polished and arrised to specification.
Bearing: Elastomeric bearing pads or setting blocks coordinated with steel shoe geometry.
Finishes: Anti-slip surface or walkable resin coat applied where the brief demands a rated finish.

Features

Various glazing options

Interlayer choice (PVB, ionoplast) driven by post-breakage and creep requirements.

Aluminium frame

Low-profile stainless shoes or fork supports with thermal isolation where needed.

Installation

Lift and temporary propping plans for long-span panels.
