Wood Charring House
Hello, we are Hiil.
Each year, Finland’s sawmill, planing, and building sectors generate about 1.5 million cubic meters of residual and inferior quality wood. A large portion of this gets chipped and burned for energy, when it could instead be utilized as cladding material in line with circular economy principles. Let’s stop wasting wood!
We source residual wood from the sawmill, planing, and construction industries, clean and char the wood’s surface, and then offer it as Kiertopuu®️ cladding solutions. Suitable for an array of cladding uses, Kiertopuu®️ products can be applied to exterior walls, terraces, noise barriers, or even indoor settings.

Kiertopuu®️ – Upcycled and Charred Timber
Kiertopuu products can be used as surface material for a wide variety of applications. The charred surface is always either washed, brushed, or oiled to prevent smudging upon touch.
Various dimensions and surface finishing options are available for the product.
Where to Use Kiertopuu®️ Products

Exterior Cladding
Kiertopuu®️ is ideally suited for exterior cladding. A charred wood surface offers both durability and visual appeal.

Indoor Surfaces
Charred Kiertopuu®️ is also apt for interior designs. Surface brushing and treatments ensure that the material does not smudge. Bulkier beams are perfect for stairs and tables, while panels and boards are great for interior walls.

Structures in the nature
We wish to see more recycled wood infrastructure from government bodies and municipalities. This wilderness cabin is made from upcycled and charred wood.
