Modified woods: Timber 101 webinar 9

The Timber 101 series is a free, expert-led introduction to timber as a construction material, designed to support informed and confident decision-making across the built environment. From architects and engineers to contractors, students and DIY builders, this series is open to anyone looking to understand how timber works – and how to use it well. It is also an excellent course for foresters who wish to understand more about the material they are producing.

Across these webinars, participants will explore timber from its biological origins to its final specification and performance in buildings. Topics include tree growth and commercial species, timber structure and properties, grading and durability, moisture behaviour, and perceptions of quality.

Each webinar stands alone but together they form a comprehensive grounding in the correct selection, specification and application of timber.

Session 9: Modified woods

This session will look at wood modification: its influence on wood properties and performance.

We will cover:

• Modified woods on the UK market - their properties, performance and end-uses
• Thermally modified – Brimstone, Abodo, Thermowood and Lunawood
• Resin-modified woods – Kebony and Rhinowood
• Chemically-modified – Accoya and Tricoya
• Charred wood
• Environmental benefits of modified woods

Audience:

This webinar is aimed at:

• Architects, specifiers and engineers
• Forestry professionals
• Construction professionals and contractors
• Students and educators in the built environment
• DIY builders, makers and homeowners
• Anyone interested in sustainable materials and low-carbon construction

Speaker: Dr Morwenna Spear, Research Fellow, BioComposites Centre

Morwenna has worked at the BioComposites Centre at Bangor University for over 15 years, conducting research into timber and a wide range of bio-based materials. She has worked with companies to scale up new technologies and processes, increase efficiency, reduce waste and to assess materials performance. She is a fellow of the IOM3, Chair of the Wood Technology Society. Morwenna is active in research into novel timber treatments; the physical, thermal, and chemical properties of wood. She is also working on energy efficient buildings and researching the environmental effects of materials and objects such as disposable and reusable facemasks.
