Create fabulous facade and interior designs with thermally modified timber with a free mind. Our fire protection solutions ensure regulatory compliance, sustainability and durable visual features of thermally modified timber surfaces.
FOR ATTRACTIVE AND SAFE WOOD DESIGNS
Our tintable, bio-based fire protection solutions ensure that your idea remains as designed, ensuring regulatory compliance, sustainability, and the long-term look and feel of your vision.
The beauty of wood should not be hidden.

Natural look and feel
The beauty of thermally modified timber remains visible with a clear or semi-translucent coloured fire protection.

Selected semi-translucent colours
The semi-translucent tones and the reaction to fire properties are protected in both interior and exterior use.

Certified reaction to fire performance
Euroclass reaction to fire performance classes up to B-s1, d0 in exterior and internal dry conditions.

Sustainable fire protection
Bio-based, low-VOC, and low-carbon flame retardants are not harmful to people or the environment.

Economical in use
Fire protection and surface finish of thermally modified timber in one solution. No extra coatings needed.

Long-term protection
The maintenance program ensures the reaction to fire performance over the life cycle of the building.

SOPHISTICATED COLOUR OPTIONS
Choose a semi-translucent tone to enhance your vision, or keep the colour of thermally modified timber with a colourless flame retardant treatment. Our Thermo Shades colour selection for thermally modified timber consists of five semi-translucent colours.
