Event Description
This session explores the specification of exterior plaster cladding using Autoclaved Aerated Concrete (AAC) , focusing on compliance pathways and the crucial role of BRANZ appraisals in validating alternative solutions. It provides building professionals with practical guidance for consent applications , as well as technical insights into selecting appropriate plaster systems, textures, and membrane paints based on environmental factors, thermal movement, and color choices.
Key Learning Outcomes
By the end of this session, participants will be able to:
- Describe the compliance pathway for AAC cladding as an alternative solution , and explain the structural, weather tightness, and durability testing required to secure a BRANZ appraisal.
- Identify the performance benefits of AAC panel systems, such as impact resistance and fire ratings , alongside application limitations including control joint placement.
- Apply specification tools such as MasterSpec to accurately detail AAC cladding systems and select appropriate substrates or cavity sizes for building consent.
- Compare the flexibility and durability of acrylic textures versus cement-based textures , and determine when to specify membrane paints with crack-bridging capabilities to accommodate dynamic movement.
- Select suitable plaster systems and coatings for dark colors with a Light Reflectance Value (LRV) under 25% to mitigate the stress of thermal expansion and contraction.
