Timber as a material offers a fantastic opportunity to the wider construction industry. It is low carbon, environmentally friendly, and – if sourced from a sustainably managed forest with FSC or PEFC certification – a renewable resource. As a result, designers and construction professionals prioritising sustainability are increasingly turning towards timber in place of other, more carbon intensive building materials in order to mitigate climate change.
The Fundamentals of Timber webinar series is intended as a detailed introduction for professionals within the built environment who are new to the material as well as timber industry staff who cross- and up-sell timber products and services. Attendees will develop a robust understanding of basic timber concepts across four two-hour webinars delivered in November and December.
