Carcassing Timber FAQ
What is Carcassing Timber?
Kiln-dried timber that is regularised is colloquially called carcassing timber. The process not only helps the timber become more durable and moisture-resistant, but it also helps preserve it for longer by minimising the impact of insect attack, fungal attacks, and more. Carcassing timber is often used in structural applications like rails, floor joists, and roof battens.
If this kind of timber sounds perfect for your applications, then you’ve come to the right store. Not only do we offer excellent prices but we deliver anywhere in South East England. From kiln-dried joists to timber framing, check out what we have on offer above!
What Wood is Carcassing Timber?
Carcassing timber, also known as joists, is treated, structural, graded softwood. Its grading is usually stamped at the end of the length to help identify it. The most common grades within the industry are C16 and C24. Although both grades are very durable and strong, C24 is considered premium, and we exclusively stock it due to its quality.
Both of the grades comply with the British Standards industry and are usually used for floor or roof joists, decking frame and shuttering.
How is Carcassing Wood Measured?
The naming and measurements of carcassing wood can be confusing. Interestingly, while carcassing wood is often referred to by their measurements in inches, for example 4×2” or 6×2”, they’re sold in metric, with the same examples being 100x47mm and 150x47mm in size with the actual finish size of 95x44mm and 44x145mm. It is important to pay attention to the measurements before making a purchase.
What Is the Difference Between CLS and Carcassing Timber?
Canadian Lumber Standards (or CLS) refer to specific standards that were originally set in Canada. However, the standard has now been improved worldwide and in the UK, most CLS-adhering timber comes from Scandinavia or Central Europe. CLS-graded wood is untreated and an excellent product to use for indoor construction. Here at Timberstore, not only do we offer carcassing timber, but we also offer CLS timber as well.
Is Carcassing Timber Treated?
Yes, carcassing timber is kiln-dried treated, which is a process that aims to reduce the moisture content of the timber, resulting in a harder, more durable, and more resistant timber treatment. Carcassing timber usually gets a grading stamp, which is required for materials used in certain structures like floor joists and roof joists. Our Crawley branch has a treatment facility so all of the timber purchased from this branch will also be treated in-house.
If you want good quality graded timber – you’ve come to the right place. Timberstore offers a diverse catalogue of carcassing timber from small timber, 47mm square up to 300mm widths, the shortest length being 2.4m and the longest 7.2m. Our extensive range and on-site cutting service play a crucial role in most orders in fulfilling orders to the exact specification needed, including firings.
