Koivui

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

The panels combine design, high quality, and the eco-friendliness and responsibility of the material. The panels are manufactured in our family-owned planing mill in Eastern Finland. 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.

Outdoors, thermally modified pine gradually takes on a silvery tone, shaped by sun and rain ☀️

With a finish, the original tone can be retained.
Left untreated, it turns a soft grey.

Both have their own character.

Which would you choose?

Mitkä asiat vaikuttivat asuntomessukohde Hietasaaren Gårdin yhteiskäyttötilojen materiaalien valintaan? KOIVUIn lämpökäsitellyt mäntypaneelit ja laudelaudat valittiin kohteeseen tarkoin harkiten niin käytännön kuin estetiikankin näkökulmasta. Paneelien ja lauteiden valintaan vaikuttivat erityisesti:

1. Tunnelma
2. Kestävyys
3. Luonnollinen ilme

- Mäntyä on käytetty aina suomalaisessa sisustamisessa ja halusimme yhdistää perinteistä ja modernia tyyliä sopivassa suhteessa. Lämpökäsitelty mänty myös kestää hyvin seinissä ja lauteissa isossa yhteissaunassa, jossa käyttöä tulee neljällä perheellä paljon. ❤️

Paneelit: Sisustuspaneeli Blankko 15x90, lämpökäsitelty mänty
Lauteet: Laudelauta Terra 26x117, lämpökäsitelty mänty

One material. Multiple scales. ✨

From a refined interior detail to an expansive façade, thermally modified pine adapts without compromise.

Its dimensional stability, natural durability, and tonal depth make it a considered choice across projects of every scale — from private homes to architectural projects.

When one material carries the entire concept, design decisions become clearer and more consistent.

How would you use it — in detail, on a façade, or both? 🤎🏡🏛️

The scent and warmth of thermally modified wood.
Soft light. Stillness.

In sauna design, material choices shape more than the look — they shape the experience.

Thermally modified wood brings natural warmth, durability, and depth to the space.

How would your ideal sauna feel — light and airy, or deep and intimate? 🤎

Thermally modified pine panels are well suited for exterior cladding where moisture, temperature changes, and weather exposure are part of everyday conditions 🌞⛈️

Thermal modification alters the wood’s structure, reducing moisture absorption and improving dimensional stability — without chemical protection. This allows the panels to perform reliably outdoors, season after season, while maintaining the integrity and appearance of real wood.

A considered choice for façades designed to endure changing conditions with long-term reliability 🤎

What qualities do you look for in materials exposed to outdoor conditions?
