50mm vs. 35mm Curtain Wall Systems — What's the Difference?
Understanding the Difference: 50mm vs. 35mm Curtain Wall Systems
50mm systems are the standard, offering strength and wide compatibility.
35mm systems deliver ultra-slim sightlines for high-end design appeal.
50mm is ideal for structural spans; 35mm is for smaller, design-led façades.
Aesthetic goals and project scale drive the decision.
Swift Rooms provides expert guidance and tailored curtain wall systems across the UAE.
Curtain wall systems come in a variety of profile sizes — the most common being 50mm and 35mm face widths. For architects, designers, and developers in the UAE, choosing the right profile affects both aesthetics and performance.
In this post, we’ll break down the differences between 50mm and 35mm curtain wall systems, when to use each, and what Swift Rooms offers for high-performance façades.
What Does “50mm” or “35mm” Mean?
The measurement refers to the visible face width of the aluminium profile from the exterior. It impacts the visual appearance and sometimes the structural capability of the system.
- 50mm System: The standard width — often used in commercial buildings, villas, and high-rise projects.
- 35mm System: A slimmer, more minimalist option — ideal for boutique architecture or high-end villas where slim sightlines are preferred.

Which Curtain Wall Profile Should You Choose?
Choose 50mm if:
- You need structural strength for larger glazed spans
- You're working on a high-rise, commercial, or mixed-use building
- You want a well-established, cost-efficient solution
Choose 35mm if:
- You’re aiming for ultra-minimalist sightlines
- A luxury design finish is important (e.g. high-end villas)
- The façade has smaller spans and lower wind load requirements
