Key Benefits of Timber Curtain Walling for Residential Projects

Timber is a material with low thermal conductivity, making it a naturally excellent choice as a core structural element in high-performance curtain walling systems. Combined with a concealed aluminium cladding system externally, this wood-aluminium composite construction delivers the durability and weather resistance of aluminium alongside the warmth, sustainability, and excellent thermal performance of natural timber.

Our timber curtain walling system achieves a U-value as low as 0.63 W/m²K – meeting and exceeding the requirements of the Passivhaus standard. The slim frames prioritise glazing area, allowing maximum natural light into the building while reducing heat loss across the facade. The result is a curtain wall system that actively contributes to energy efficiency, reduced heating demand, and improved building performance ratings across Irish residential projects.

Bespoke Timber Curtain Wall Designs for Every Project

Available in engineered redwood as standard – with engineered hardwood and European oak as additional options – our timber curtain walling system can be specified with any RAL colour for the external aluminium cladding, and finished internally using a factory-applied, three-coat water-based Teknos microporous paint or stain system. This level of configuration flexibility makes it an excellent choice for architect-led and self-build projects where material quality and aesthetic precision matter.

Any combination of tilt and turn windows, casement windows, entrance doors, and sliding doors can be integrated seamlessly into the curtain walling system – maintaining consistent sightlines and facade continuity. Our specialist curtain walling team provides full technical support throughout specification, supply, and installation, ensuring every timber curtain wall system we deliver performs as designed for the lifetime of the building.
