Thermally modified panels

KOIVUI® thermally modified panels are an excellent choice for both interior and exterior cladding in all climate conditions.

Design, quality and eco-friendliness

KOIVUI® panels combine design, high quality, and the eco-friendliness and responsibility of the material.

The raw material, Finnish thermally modified pine, is an environmentally friendly, chemical-free, and durable material that offers both longevity and a beautiful, natural appearance.

The sorting process of the material and careful quality control ensure that only high-quality panels are delivered to your project.

Interior and exterior cladding

The low-maintenance and durable thermally modified wood is an excellent material for exterior cladding and also works beautifully on indoor surfaces.

Thermal treatment modifies the wood’s properties, making the cladding panels suitable for even the most challenging climate conditions. The panels are dimensionally stable, pitch-free, and have excellent decay resistance.

In addition to its beautiful appearance, the ecological thermally treated material does not emit any pollutants into the indoor air.
