When building a deck in Canada, one of the key decisions you’ll face is choosing the right type of wood. Among the many options available, pressure-treated lumber is one of the most common choices. But is it really the best option? Or are there better alternatives worth exploring? In recent years, hardwoods like IPE (Brazilian walnut), Red Balau Batu and Yellow Balau Bangkirai have gained popularity for their unmatched durability, strength, and visual appeal.
In this article, we’ll break down when it makes sense to use pressure-treated wood, the pros and cons, and what other materials might suit your budget, climate, and design goals.
What Is Pressure-Treated Wood?
Pressure-treated wood – typically made from pine – is infused with protective chemicals under high pressure to guard against rot, mold, insects, and moisture. This treatment makes it especially resistant to outdoor conditions, which is why it’s so widely used for decks, patios, fences, and soffit.
In Canada’s climate – with cold winters and high humidity – this kind of protection can be especially beneficial.
Key Benefits of Pressure-Treated Wood
- Resistance to Rot and Insects
In damp regions like coastal B.C. or rainy parts of Ontario, pressure-treated wood holds up better and longer than untreated wood. - Cost-Effective
It’s cheaper than cedar or composite decking, making it a go-to option for budget-conscious homeowners. - Easy to Work With
Pressure-treated wood is simple to cut, drill, paint, and install – ideal for DIY projects. - Decent Longevity
When properly installed and maintained, it can last 15 to 20 years or more.
Downsides to Consider
- Chemical Exposure
Today’s treatments (like copper azole or alkaline copper quaternary) are considered safe, but they’re still chemicals. This makes pressure-treated wood less ideal for surfaces where kids play or food is handled. - Color Fading
Without a UV-protective finish, the wood will gradually turn gray from sun exposure. - Ongoing Maintenance
To keep it looking good and structurally sound, it needs regular sealing or staining. It can also crack or warp with temperature swings.
Why Consider Hardwoods Like IPE or Balau?
IPE, Red Balau Batu and Yellow Balau Bangkirai are dense tropical hardwoods that outperform nearly all other decking materials. They’re especially favored in high-end and commercial builds. These woods can be found at specialty hardwood shops as our store is Kayu™.
Advantages of IPE and Balau
- Exceptional Longevity
These woods can last 40 to 75 years without chemical treatment. They’re naturally resistant to moisture, pests, mold, and UV damage. - Luxury Look
Deep, rich tones and a smooth, polished texture make them a favorite for upscale decks and patios. - Unmatched Strength
Incredibly dense and stable, they hold up against freezing temps, intense sun, snow, and rain – perfect for the Canadian climate. - Low Maintenance
Left untreated, they develop a stylish silver patina. If you prefer the original color, a once-a-year application of natural oil will do. - Eco-Friendly Option
Free from chemicals, and when FSC-certified, they’re a fully sustainable and responsible building material. - Fire Resistant – High fire resistance, meeting Class A standards for fire retardancy.
What’s the Trade-Off?
- Price
IPE can cost 3–5 times more than pressure-treated wood. But it’s a long-term investment that can pay off over decades. Many homeowners searching for IPE lumber Canada often weigh the higher upfront cost against decades of minimal upkeep. - Harder to Work With
These hardwoods are extremely dense, which means they require special tools and experienced installers. - Heavier Weight
IPE, Red Balau Batu and Yellow Balau Bangkirai are significantly heavier, something to factor in when planning the structure.

Who Should Consider Hardwoods?
- Homeowners who want long-term durability without frequent replacements
- Anyone who values design, aesthetics, and is willing to invest for quality
- Eco-conscious buyers who want to avoid chemically treated materials
- Professionals building premium residential or commercial outdoor spaces
Whether you’re planning a backyard retreat or a luxury rooftop space, IPE decking Canada has become a top-tier option for those who want timeless quality and performance.
Conclusion
Pressure-treated wood has its place – it’s budget-friendly, durable, and gets the job done for a typical backyard deck. With proper care, it’ll last 15 -20 years max.. But if your priorities include natural materials, high-end appearance, sustainability, and maximum lifespan, hardwoods like IPE, Red Balau Batu and Yellow Balau Bangkirai are worth serious consideration. Don’t just focus on the upfront cost – think long-term. In Canada’s harsh climate, investing in hardwood can save money and hassle down the line, especially for premium or commercial builds.
Pressure-treated wood is lumber that has been infused with chemical preservatives under high pressure to protect it from rot, insects, and decay – especially in damp environments.
