High quality, consistent and dry stored
At Champion Timber, we only source prime quality timber from sustainable sources. Each joist is made to our specific requirements from slow-grown Scandinavian redwood pine. When it reaches us we store it flat undercover to ensure that our treated timber is straight, smooth and consistent.
Our Joistmate Xtra timber is regularized so that each joist is consistent in size. This means less wastage and saves you time on the job. We also add eased edges, making them easy to handle and work with.
Strong as standard – graded to C24 at no extra cost
Our Joistmate range is all graded to C24 (EN14081-2). This means that it is stronger than C16 equivalents and can support higher loads. This extra strength gives you the option of using wider spans, reducing the material costs for your build. Alternatively, you can stick to standard spans and complete the build to a higher spec.
What is C24 timber?
C24 is a strength classification for softwood timber. It defines the species that can be used – the ‘C’ stands for conifer, though not all coniferous species can be used for all grades. The standard also sets limits for the number of visual imperfections such as knots and sap stains. Finally, it defines the stress limits for the timber, looking at bending, tension, compression and shear tolerances.
Pressure treated for long life
All our Joistmate Xtra products are pressure treated with Tanalith E preservative. This provides protection against fungal decay and insect attack, even in ground contact situations. For roof timbers and other dry uses for joists, this pressure treatment gives the timber a service life of at least 60 years.
