Frequently Asked Questions

What strength classes are available for construction timber?

Structural timber is graded into different strength classes such as C14, C24, and C30. C24 is the most common and is used for the majority of construction projects. 

When is C24 used compared to C14?

C24 is used for load-bearing structures such as beams and joists in floor systems. 
It is stronger and more durable, making it suitable for constructions that need to withstand higher loads. 

C14 is typically used for wall studs in load-bearing interior and exterior walls 
where the requirements for deformation are not as high. 

What is the difference between untreated and treated timber?

Untreated timber is natural and used indoors or in protected environments. Treated timber is treated to resist moisture and rot, making it suitable for outdoor use. 

How do I store timber correctly to prevent damage?
  1. Protect from Moisture: Store the timber in a dry place, protected from rain and ground moisture. Use pallets or similar supports to keep the wood off the ground. 
  1. Ventilation: Ensure that air can circulate around the timber. This helps prevent mould and rot. 
  1. Protect from Sunlight: Avoid direct sunlight, as it can cause cracking and warping. 
  1. Covering: Use a tarpaulin or other protective covering, but make sure there is space for the air to circulate. 
  1. Regular Inspection: Check the wood regularly to ensure it hasn’t been damaged or exposed to moisture. 
How do I choose the right sizetimber?

The size you need depends on what you’re building. Common dimensions are 45 x 95 mm and 45 x 145 mm. For load-bearing structures such as roof trusses, C30 may be necessary. Contact customer service for assistance.

reliability and versatility

CLS timber

CLS timber refers to wood that meets the Canadian Lumber Standard. It is a softwood that has been planed and rounded on all sides, resulting in a smooth and even surface. Originally from Canada, CLS timber is valued for its high quality, consistent dimensions, and wide range of uses. It is typically made from spruce, pine, or fir – collectively known as SPF (Spruce-Pine-Fir).

Thanks to its reliability and versatility, CLS timber is suitable for many types of projects. It’s commonly used in new constructions, extensions, structural framing, as well as for building custom furniture and various DIY projects.
