This presentation aims to give a broad and as detailed as possible overview of fibre gypsum as an alternative to concrete blockwork and plasterboard/drywall as an internal wall material. The CPD focuses on the pros and cons of wall materials and compares performance criteria in the context of Modern methods of construction and the demands of carbon reduction and circular economy considerations. It covers the essentials on the nature of the material, how it is made and used as an internal walling material as part of an overview of wall construction technology and principles. By the end of this CPD delegates ought to have: An overview of a highly flexible, alternative material in MMC; Improved understanding of Fibre Gypsum as a relevant and carbon reduction material and how it can be used effectively; A thorough background in the nature and properties of Fibre Gypsum how it can be used to satisfy modern approaches to sustainable building whilst offering a fine, robust material; An understanding of typical details and cases using fibre cement in construction; Knowledge on how Fibre Gypsum meets legislative requirements and standards in health and safety, approved documents and standards and durability.
