It is crucial to purchase CCA treated timber that is best suited for your application. Now, what does that really mean? It’s not only about whether the is CCA treated, but more importantly, which hazard class the timber is treated to. The treatment process categorizes timber into different CCA hazard classes, ensuring tailored protection based on the anticipated environmental challenges, specifically pertaining to weather and insect exposure.
Our goal is that, after reading this blog, you will understand how the CCA hazard classes work and therefore know exactly what information you need to gather before you’re on your way to purchase your timber.
Why is timber is treated with CCA.
While timber is an excellent material to build with, we know that it is also biodegradable. Biodegradability is the ability of a material to be broken down into simpler substances by the action of living organisms, such as bacteria, fungi, and other microorganisms, as well as environmental factors like moisture and temperature. This is great for the environment, however, not so much for structures. We need the timber to be able to last longer.
That’s where CCA treatment comes into play; the chemicals are intended to protect the timber from these elements, significantly enhancing its durability. To learn more about the CCA treatment process, please click on the following link: CCA pressure treatment process
Understanding the CCA hazard classes
During the treatment process, timber is treated based on various hazard classes, tailoring the treatment to its most suitable application. For instance, if you’re planning to construct a deck exposed to potential harsh weather elements like heavy rain, intense sunlight, and potential insect attacks, it’s essential to choose timber that can effectively withstand these threats.
Here are the CCA hazard classes in short:
H2 – The timber is treated for above ground, indoor use: e.g. Interior, flooring, furniture, joinery.
H3 – The timber is treated for outside, above ground use: E.g. pergola’s, decks, verandah posts.
H4 – The timber is treated for outside, inground use: E.g. Fence posts, garden walls, vineyards.
H5 – The timber is treated for use in areas with constant moisture and dampness. E.g. Piles, wall retainers
You might think that using a good sealer is enough to protect timber. However, it’s important to know that sealers mainly protect the surface of the wood and need frequent reapplication.
On the other hand, CCA treatment goes deeper. The chemicals penetrate the timber, creating a strong and long-lasting defense against decay, insects, and environmental stress. Unlike sealers, CCA-treated timber doesn’t require constant retreatment. Once treated initially, the timber undergoes a lasting transformation, providing enduring protection without the hassle of repeated applications.
What you can do, is, apply a sealant to CCA treated wood to provide even more protection, however, we will dive into this topic another time.
Regulations of CCA treatment
CCA timber treating companies should follow SANS (South African National Standards) 10288 regulations. This is to promote safety, environmental sustainability, and overall product quality. It is therefore highly important that you purchase from a trusted supplier.
