Thermawood Decking vs Composite: Real Wood or Plastic?
Composite has its place.
It is low-maintenance. It is common. It comes in a lot of colors. For some people, that is enough.
But composite is still plastic decking.
Thermawood decking is real wood.
That is the difference.
Thermawood is thermally modified solid wood changed using heat and steam. No plastic cap. No composite core. No chemical treatment. No fake wood grain stamped into a board.
Real wood.
Just built to handle moisture, sun, movement, and outdoor life better than traditional decking.
Composite Is Low-Maintenance — But It Is Still Plastic
Composite decking can make sense for somebody who wants a uniform color and does not care whether the deck feels or looks like real wood.
But it has limits.
Composite can get hot in direct sun.
It can fade.
It can scratch.
It can stain.
It can expand and contract in heat.
And once it is worn out, damaged, or somebody gets tired of the color, it gets replaced.
You cannot sand it.
You cannot refinish it.
You cannot bring it back to life.
It is a product made to be installed, used, and eventually torn off.
Thermawood Is Real Wood That Can Last
Thermawood decking is real wood from top to bottom.
It has real grain.
Real texture.
Real character.
And unlike composite, it can be cleaned, sanded, refinished, and maintained over time instead of simply replaced.
The thermal modification process changes the wood using heat and steam.
No organic material = no cupping, warping, or gapping.
That is what gives Thermawood its stability.
Traditional wood decking can move, cup, splinter, warp, and react to water as seasons change.
Thermawood does not react the same way.
That makes it a strong option for:
- Coastal homes
- Pool decks
- Docks
- Covered porches
- High-humidity areas
- Outdoor kitchens
- Pergolas
- Cladding
- Exterior trim
- Projects with heavy sun and weather exposure
No Chemicals Needed
A lot of exterior wood products rely on chemical treatment to fight moisture, insects, fungus, and rot.
Thermawood is changed using heat and steam only.
The wood itself is modified.
No chemical treatment.
No plastic cap.
No composite core.
No trying to make plastic look like wood.
That matters to people who want a natural real-wood deck without putting a chemically treated product under their feet.
Direct Sun Is Different Too
Composite decking can get hot in direct sun.
Anybody who has walked barefoot across a dark composite deck in the middle of summer knows exactly what that means.
Thermawood is still wood.
It does not act like a plastic board heating up in the sun.
It gives you the look and feel people actually want from a deck, without the same movement issues traditional wood can bring.
Does Thermawood Need Maintenance?
It is still real wood.
So yes, it should be cared for like real wood.
Keeping it clean, allowing it to drain, and maintaining the finish or oil if you want to preserve a certain color is part of owning a real wood deck.
But Thermawood is not ordinary decking.
It is built to handle moisture and movement differently, which means you are not fighting the same cupping, warping, gapping, and splintering issues that make people regret traditional wood decks.
Which One Is Right for You?
Choose composite if you want a plastic deck with a uniform color and you are comfortable replacing it when the time comes.
Choose Thermawood if you want real wood, real grain, real character, and a deck that is built for real outdoor life.
A deck should not look like plastic just because it has to handle water.
