Sustainability Certificates

FSC®

The Rationel AURA window is a contemporary, timber-framed solution that combines Scandinavian design clarity with high environmental performance. Crafted from FSC-certified Scots pine, it is engineered to last around 60 years when properly maintained, offering a renewable and low-carbon alternative to aluminium or uPVC frames. Its slim, flush profile maximises daylight while supporting low-energy building standards, with triple-glazed options delivering U-values down to 0.78 W/m²K and sound reduction up to 42 dB.

By using sustainably sourced timber with a high proportion of durable heartwood, and providing Environmental Product Declarations, AURA supports responsible material cycles and reduced CO2 footprints, making it well suited for projects targeting Passive House or other sustainable building certifications.
