Care Instruction
Care Instruction
1. Seal Before Use
Apply wood oil, hardwax oil, or a suitable wood sealant before first use to protect against moisture and stains. Reapply as needed depending on use and cleaning frequency.
2. Wipe Spills Immediately
Although thermowood is moisture-resistant, prolonged exposure to water or liquid can still leave marks. Wipe up spills with a dry or slightly damp cloth.
3. Use Mild Cleaning Products
Clean the surface with a soft cloth and a mild soap solution. Avoid abrasive cleaners or strong chemicals, which may damage the protective finish.
4. Avoid Direct Heat and Cutting
Always use trivets for hot pots and cutting boards for food prep. Direct heat and knife blades can leave marks even on treated wood.
5. Maintain Finish Periodically
Depending on use, reapply your chosen wood oil every 12 months to maintain water resistance and surface durability.

Thermowood Acacia Windowsills – Stable and Naturally Beautiful
Thermowood Acacia windowsills are made for interiors where moisture and sunlight are constant challenges. The thermal modification process — using only controlled heat and steam — enhances the acacia wood’s density and dimensional stability, making it highly resistant to warping, cracking, and mold.
Each sill showcases the deep, golden-brown color characteristic of thermally modified acacia, with the tone running through the full thickness of the wood. This means scratches or sanding won’t expose lighter layers, and the surface maintains its elegant look for years.
Designed for both new builds and renovations, these windowsills fit naturally into modern, rustic, or minimalist interiors. Their durable build supports everyday use — from flowerpots to décor — while maintaining a healthy, chemical-free indoor environment.
Choose Thermowood Acacia for a timeless, sustainable solution that enhances both comfort and design in your living space.
