Introduction

Bolted glass has become a key element in contemporary architecture, enabling the design of façades that are transparent, lightweight and structurally efficient. Behind this architectural clarity lies a continuous evolution of fixing systems, shaped by growing demands in terms of performance, durability and safety.

SADEV — a recognised specialist in structural glass hardware — supports this evolution with high-performance solutions engineered for the most demanding architectural projects.

SADEV Solutions Driving Innovation in Structural Glass

Double-Skin Façades: Efficiency and Transparency

Double-skin façades are increasingly adopted for high-performance buildings. This system, composed of two glazed layers separated by a ventilated cavity, enhances:

• Thermal insulation
• Acoustic comfort
• Overall energy performance

Integration of SADEV fixings

SADEV spider fittings, glass supports and bespoke fixings fit naturally within these complex façade configurations. Designed for large-format glazing and high mechanical constraints, they offer:

• Secure and durable installation
• Clean visual integration
• Optimised transparency

Case Study: Carré Saint Cyr (Vaudreuil)

The façade incorporates permanent signage while allowing the installation of temporary communication elements.

The glazing becomes an architectural and visual identity tool.

Advanced Materials and Enhanced Global Performance

To meet aesthetic and technical expectations, materials continue to evolve. The use of 316 stainless steel, with its high corrosion resistance, ensures long-lasting performance in demanding environments.

Well-designed glass façades significantly support building efficiency. SADEV develops systems that improve:

• Thermal performance
• Acoustic performance
• Natural daylight transmission

Modularity for Complex and Large Glazed Surfaces

Flexible Systems for Architectural Freedom

Modern fixing systems must adapt to diverse façade geometries. SADEV spider fittings allow:

• Absorption of building tolerances
• Controlled glass movement
• Simplified on-site adjustments

Connectors between the structure and the glass spiders feature a minimal visual impact, preserving the purity of the façade envelope.

Load Management and Mechanical Safety

SADEV systems are designed to handle mechanical loads while protecting the glazing. Controlled tolerances integrated into the fixings accommodate:

• Wind loads
• Snow loads
• Thermal expansion
• Structural movement

A combination of bearing points and stabilising points ensures:

• Vertical load support
• Perpendicular load transfer
• Freedom of movement without stress on the glass

This precise distribution enhances long-term performance and reduces the risk of breakage.

Tailor-Made Engineering with the CONSTRUCT Range

Discreet Integration for Contemporary Architectures

CONSTRUCT solutions allow fixings to be integrated within the glass thickness or discreetly positioned inside structural frames, contributing to a minimal and refined aesthetic.

The CONSTRUCT range includes bespoke structural fixings designed for unique architectural concepts.
