Reynaers SlimWall 35: Light, Strong, Smart

A slender, certified and customizable curtain wall system for contemporary architecture

In today’s evolving façade design landscape, SlimWall 35 by Reynaers Aluminium emerges as a refined yet robust response to the demand for minimalist aesthetics paired with high technical performance.

It’s a stick-built curtain wall system engineered to deliver maximum transparency, thermal efficiency, and design freedom, all within a compact structural profile.

Minimal Lines, Maximum Impact

The essence of SlimWall 35 lies in its reduced sightlines: just 35 mm for both mullions and transoms — inside and out.

This clean, narrow frame allows architects to flood interiors with daylight, blur indoor-outdoor boundaries, and achieve architectural openness in even the most constrained urban contexts.

But the system’s elegance conceals a powerful performance core:

• Passive House-certified performance with Uw values down to 0.8 W/m²K
• Air-tightness AE 1200 and water-tightness RE1200, ideal for extreme climates
• Wind load resistance Class A5 (2000 Pa) for demanding structural contexts
• Burglar resistance RC2, a key feature for residential and commercial applications

These metrics make SlimWall 35 a versatile solution for a broad range of building types—from private residences and hotels to corporate headquarters and cultural venues.

Designed for Performance and Freedom

SlimWall 35 reflects Reynaers’ dedication to architectural clarity, offering a suite of integrated design features that enhance both form and function:

• Hidden drainage: No visible plastic caps, just clean geometry
• Clip-on cover caps: For fast customization and visual variety
• Solar shading: Optional accessories for passive cooling
• Color options: Over 450 finishes and tones to match any concept

These design tools allow architects to maintain creative control while ensuring that the system’s performance remains uncompromised.

The modularity and technical integrity of the SlimWall profile also support efficient fabrication and installation.

Certified Sustainability and Long-Term Performance

SlimWall 35 is Passive House certified, a notable achievement for a slim-profile curtain wall system.

Engineered to hold glass panels up to 52 mm thick and weighing as much as 450 kg, it offers exceptional thermal insulation and long-term durability thanks to high-grade materials and manufacturing standards.

Reynaers goes beyond basic sustainability by designing systems for circular use: SlimWall 35 can be disassembled, repurposed, or recycled—contributing to a longer, more responsible lifecycle.

Its production aligns with environmental standards, reflecting the company’s long-term commitment to sustainability in façade systems.

A System That Doesn’t Compromise

In an era where façades are expected to deliver comfort, energy efficiency, and visual appeal, SlimWall 35 presents itself as a comprehensive solution.

It empowers designers with a compact but powerful toolkit to create responsive, elegant building envelopes that perform across categories.

SlimWall 35 is not just a curtain wall—it’s a statement of architectural intent, where less truly becomes more, and where technical performance supports, rather than compromises, architectural vision.
