Material Selection Matters Handout

Pdf Summary

In this document, John Straube, a building science specialist, explores the considerations for material selection when constructing six-storey buildings. He explains the agents of material deterioration and the four primary material categories: metallic, polymer/organic, mineral/ceramic, and composite. He also discusses the challenges and trends in construction, such as faster construction and design cycles, higher density buildings, and better energy performance.<br /><br />Straube explains that the choice of material depends on the specific project needs, and different materials have different properties. For example, wood is low-cost and easy to escape in fire, while concrete provides integral fire-proofing and is durable. He also explores the challenges associated with different materials, such as moisture during construction, shrinkage of wood, and fire protection. He highlights the complexity and new challenges in constructing tall wood buildings, including construction moisture and shrinkage.<br /><br />The document also discusses the importance of thermal resistance in wall assemblies and reducing unnecessary thermal bridging. Straube emphasizes the trend towards exterior air barrier approaches and sealed sheathing membrane approaches in wood-frame buildings. He also mentions the requirements and regulations related to air leakage in building codes.<br /><br />Overall, the document provides an overview of materials and systems used in building construction and highlights the challenges and considerations for material selection in constructing six-storey buildings.
