About Our Treated Timber Joistmate Xtra 75mm

Our range of treated carcassing is straight, smooth and consistently sized construction timber.

It has eased edges for faster handling on site.

We stock structurally graded C24 which complies with EN14081-2 and is pressure preservative treated with Tanalith E for a durable finish.

Available in a range of finished sizes  and lengths.

What is C24 Timber?

C24 graded premium structural timber offers greater strength than C16 timber, making it a more demanding grade that can handle higher loads and wider spans.

It is a better-quality structural option because it can take up to 50% longer for these timbers to grow, meaning that they have more growth rings. The more growth rings a piece of wood has, the higher its overall density, which in turn means that it has greater natural durability and improved stability.

The tighter the growth rings of the wood, the better-quality piece of wood that you are dealing with.

Do I need Treated Structural Timber?

If the timber is going to be placed in an area where attacks from external problems such as moisture or fungal attacks, are likely to cause major problems, then we strongly recommend purchasing treated structural timber.

For all the following applications, we generally recommend using a treated structural timber:
