Questions & Answers

Q: What are the advantages of using CLT in construction?

CLT offers several advantages, including being quicker, cheaper, cleaner, and quieter to build with compared to traditional materials like concrete and steel. It also has excellent sustainability credentials.

Q: How are CLT panels manufactured?

CLT panels are manufactured in a factory environment from sustainably sourced timber. The timber is cut into layers, glued together using non-toxic adhesive, and pressed to create strong structural panels.

Q: Can CLT panels be prefabricated off-site?

Yes, CLT panels can be prefabricated off-site and delivered to the construction site as needed. This construction method is ideal for projects with limited on-site storage capacity, reducing construction time and cost.

Q: What are the fire resistance properties of CLT?

CLT has inherent fire resistance properties. When exposed to fire, the outer layer of timber chars and forms a protective layer around the structural core, retaining its load-bearing capacity. It can withstand fires for 30 to 120 minutes, depending on its engineering.

Summary & Key Takeaways

• CLT is an engineered timber product that offers sustainable credentials and is being used to construct homes, offices, schools, and towers.

• The material is manufactured from sustainably sourced timber, with spruce being the most common choice.

• CLT panels are produced in a factory environment, glued together using non-toxic adhesive, and hydraulically pressed to create high-strength structural panels.
