Timber curtain walls (TCWs) offer more than just expansive glass and daylighting potential — they serve as a bridge between natural aesthetics and high-performance building design. From the warmth of wood to advanced glazing options and tailored finishes, TCWs deliver remarkable design versatility with unmatched sustainability benefits.

Built for Beauty and Performance

At the core of every high-performing TCW system is precision-engineered wood (mass timber) and premium glazing. This combination ensures structural strength, thermal efficiency, and design flexibility — all while supporting low-carbon building goals.

Wood Species: A Natural Expression of Design

Few materials rival the tactile warmth and richness of natural wood. Unicel Architectural offers a wide selection of wood species to complement and elevate architectural visions. Whether your project calls for a modern, minimalist feel or a more traditional expression, our TCWs are available in the following species:

• Douglas Fir
• Pine
• Mahogany
• Sapele
• Red Cedar
• White Oak
• Maple

Each wood species is carefully selected and engineered for strength, durability, and aesthetic character — allowing architects and designers to specify the look and performance best suited to the project’s context.

Cap Finishing: The Final Detail

Finishing details matter — and Unicel Architectural’s cap systems deliver a refined look while protecting the underlying structure. Snap-on caps conceal and seal the pressure plates of the TCW for a clean, streamlined appearance. Available options include:

• Solid eucalyptus wood caps
• Custom-colored aluminum snap-on caps

Each cap style is designed to enhance durability while providing design flexibility to match the rest of the building envelope.
