◄ We’re constantly innovating, and our Sylva by Stora Enso kit of parts – a range of prefabricated wood-based products for low carbon buildings – are continuously changing to meet the needs of customers, whether that’s developers, investors, or architects. We are always developing additional offerings customers can plug-in alongside the kits themselves, whether that is protective coatings or on-site installation apps, like Sylva360.


MJ: HAS STORA ENSO CALCULATED THE CARBON BENEFITS OF YOUR SYLVA KITS VS CONVENTIONAL CONSTRUCTION IN CONCRETE AND STEEL? MD: Our Sylva kit of parts can be applied flexibly in nearly every building type including residential, offices, schools, and even large-scale industrial buildings with up to 36m clear spans.


When we analysed the whole life carbon


in a study for a typical mixed-use development, we found a traditional concrete frame was responsible for 8.68kg of CO2
