CCA, or chromate copper arsenate, is a chemical compound used as a wood preservative to protect against decay and insect damage. It is the most commonly used preservative in the United States and has been used for over 70 years to extend the life of timber structures, such as decks, fences, and utility poles. CCA is a highly effective treatment that has been extensively tested and approved by regulatory bodies, including the Environmental Protection Agency (EPA).

PY Timber House is a company that specializes in supplying quality building materials to Victorians. One of the products they offer is CCA, a wood preservative commonly used to protect against termites and decay-causing fungi. This article will explore the benefits of CCA treatment and how PY Timber House can help you protect your timber structures.

Benefits of CCA Treatment

As mentioned earlier, CCA treatment provides several benefits to timber structures. Here are some of the advantages that you can enjoy:

Protection Against Termites:

CCA treatment is highly effective in preventing termite damage. Termites are known to feed on timber, which can weaken the structure of your building. CCA treatment makes the timber resistant to termite attack, helping to preserve its strength and integrity.

Resistance to Decay:

CCA treatment also protects against decay-causing fungi. These microorganisms thrive in moist environments and can cause the timber to rot. CCA treatment prevents the growth of fungi, ensuring that your timber structures last longer.


CCA treatment makes timber structures more fire-resistant. This is particularly important for buildings located in areas prone to wildfires. CCA-treated timber is less likely to catch fire, reducing the risk of property damage and personal injury.


CCA treatment is a cost-effective way to extend the lifespan of your timber structures. While the initial cost may be higher than untreated timber, the long-term benefits, including reduced maintenance costs and a longer lifespan, make it a more economical choice.

Application of CCA Treatment by PY Timber House

PY Timber House offers CCA treatment for timber structures. The process involves dipping the timber in a solution of CCA and subjecting it to vacuum pressure to force penetration of the solution into the wood. This process ensures the treatment penetrates deep into the timber, providing long-lasting protection against insect damage, decay, and fire.
