Façade glazing is selected for solar control, safety, spandrels, weight and allowable deflection; one build-up rarely suits the whole envelope.

FWS 50 SG
The Structural Glazing variant of FWS 50 for façades intended to read as a continuous glass plane. It supports flush all-glass and semi-structural expressions with AWS 114 opening-unit integration.

SYSTEM PARAMETERS
Structural glazing is more than removing the cap.
In FWS 50 SG the structural IGU geometry, cassette logic, joint sealing, glass support and thermal movement become critical design parameters.
50 mm
50–255 mm
from 1.4 W/m²K
32–44 mm
up to 2600 × 4200 mm
20 mm
up to 44 dB
AE1200
RE1200
2.0 / 3.0 kN/m²
I5 / E5
up to RC2
FWS 50 SG adds structural glazing to the usual façade engineering. Glass size, edge zone, silicone bite and material compatibility are determined for the actual module.

This image shows the system's profile geometry, chambers, thermal breaks and glazing zones. The final junction is selected for the opening scheme, glass build-up, dimensions and project loads.

GLASS ENVELOPE
Minimal exterior metal.
Flush all-glass or semi-structural appearance
Large-format glazed fields
Integration of AWS 114 opening units
Horizontal or vertical architectural accentuation where cover caps are used
STRUCTURAL GLAZING
The joint and bond line become structural components.
SG façade engineering extends beyond mullion sizing. Structural silicone, cassette, glass edge, wind pressure, dead load and building movement must work together.
Structural joint
Bond-line geometry and materials follow the façade cassette technology and approval route.
Glass
Thickness, heat treatment, deflection, edge stresses and sealant compatibility are reviewed.
Installation
Plane, joint width, installation sequence and drainage are controlled on site.
BIFORIUM / PRACTICE
A system only works as a whole with glass, hardware and installation.
Anchors, movement joints, pressure, drainage and roof/wall junctions are part of the system, not an afterthought.
Open engineering details ↗Opening inserts, actuators and ventilation are coordinated before the façade static design is finalised.

FAQ / SPECIFICATION
Questions to close before specification.
Can the system be selected only from catalogue performance?
No. Published values help shortlist options, but the finished element still has to be checked for size, glazing, weight, hardware, loads and installation detail.
Does every opening need the same glazing build-up?
Not necessarily. A south-facing elevation, a bedroom near traffic, a large fixed pane and an entrance leaf can require different glazing within the same project.
When should the installation detail be coordinated?
Before the final order. Finished-floor level, insulation, waterproofing, structural support and drainage can change the frame, threshold or final manufacturing size.
HOW TO READ THE DATA
Six values that shape the result.
A catalogue maximum is not the rating of every fabricated element. Classes depend on size, opening scheme, glazing, hardware and the tested configuration.
