Curtain Wall Types: Silicone, Capped and Hybrid Systems
28 March 2026 // 5 min min read // ICS Technical Team Technical

Curtain wall systems are engineering structures that form the outer shell of buildings. They resist wind and seismic forces without transferring structural loads to the building.

Silicone Curtain Wall

In silicone curtain walls, glass panels are bonded to the aluminium frame with structural silicone. From the outside, only the glass surface is visible; aluminium profiles are concealed.

Advantages: - Seamless glass appearance - Modern and minimalist aesthetics - High light transmittance

Capped Curtain Wall

In this system, glass panels are mechanically fastened with aluminium cap profiles. Cap profiles are visible from the outside and can be used as a design element.

Advantages: - Easy maintenance and glass replacement - Mechanical security - Various cap profile options

Sunshade Integration

Sunshades can be integrated into both systems. Horizontal or vertical aluminium louvres control sunlight, preventing excessive indoor heating and reducing energy consumption.

Choosing the Right System

Project location, building height, wind loads and aesthetic expectations are decisive factors in system selection. ICS Alüminyum's technical team offers project-specific wind load calculations and detailed design services.
