Cross-laminated timber: design and performance

TRADA image

Cross-laminated timber (CLT) is increasingly being used within residential and non-residential buildings. Offering a significant strength to weight ratio, improved installation speeds, reduced on-site waste and an inherent high standard of airtightness, CLT also has the advantage of being a renewable resource that can combine carbon sequestration with the design flexibility required in modern building practice.


This book has been written to cover the design and performance of CLT within construction. Chapter 1 showcases its uses for architects and building designers. Chapter 2 focuses on design principles and Chapter 3 covers CLT performance, including structural design, fire performance, acoustics, thermal performance, durability, appearance, and sustainability. Chapter 4 concludes the book with thirteen case studies based on several building types. Highly illustrated with photos and technical drawings, this book demonstrates the versatility of CLT as a sustainable, engineered timber solution and will assist architects, engineers and their clients looking to work with this material.


Researched and written with contributions from Adrian Young, Patrick Hislop, Hugh Strange Architects, Arup, B&K Structures, Eurban, KLH UK, Ramboll, Stora Enso, Waugh Thistleton Architects, Exova BM TRADA, and the Structural Timber Association.
