What Homeowners Should Know Before Choosing Wood
Let’s face it — the weather isn’t always your friend. One day it’s dry, the next it’s soaking wet. That’s why picking the right material for your deck, sauna, cladding or feature wall is key.
Choosing between natural wood and thermowood isn’t just about how it looks — it’s about how it lasts.
What is Thermowood, Really?
Thermowood starts as regular wood — typically pine, spruce, or ash — and is heat-treated in a steam-filled chamber at 215°C. The process is 100% chemical-free and changes the structure of the wood for the better.
Here’s what that does:
- All moisture is removed → stability improves
- Sugars and resins disappear → bugs and mould won’t thrive
- The colour darkens → rich, deep tone without stains or paint
The result is a premium wood that handles outdoor conditions for 25+ years without cracking, twisting, or constant treatment.
Natural Wood: Classic Look, Constant Work
Natural, untreated wood looks great — no question there. But it needs regular attention to stay that way:
- Requires sealing or painting every year
- Cracks and absorbs moisture over time
- Can twist or warp in wet conditions
- Attracts insects unless treated chemically
If you’re into upkeep and DIY care, it might work. But if you want a long-lasting solution with less stress, thermowood is worth a closer look.
Why More Projects Are Using Thermowood
Across gardens, patios, and outdoor rooms, more people are picking thermowood — and here’s why:
- Stays straight and stable for years
- No need for chemicals, paints or sealants
- Smooth surface, gentle on bare feet
- Resistant to moisture, wind and heat shifts
- Pet- and kid-safe
- Elegant appearance with low maintenance
- Oh, and it smells fantastic
Where to Use It
Thermowood is versatile and works anywhere you’d consider timber:
- Decking and patios
- Exterior cladding
- Outdoor and indoor saunas
- Ceilings and accent walls
- Pergolas, fences, benches, and more
Whether you’re restoring a cabin or building modern architecture, it blends in beautifully.
Is It Expensive?
Not really. The initial price might be a bit higher than softwood, but the savings add up:
- No yearly painting or sealing
- No costly repairs from warping or cracks
- Less time spent on maintenance
- Longer lifespan = better value
Thanks to direct sourcing and efficient logistics, we’re often 20–30% more affordable than locally treated timber.
