Hand-split shingles · Opole, Poland

A roof that outlives the people who build it.

We split oak, larch and spruce by hand along the grain, so the wood's own fibres decide where it breaks. The surface sheds water the way a duck's feathers do — untreated, unpainted, good for a century.

Why split shingles

Water has never found a way through a feather.

Splitting along the grain opens the wood's closed capillaries. Each shingle lays flat on the next, and each gives water downward because there is nowhere to draw it in. The wooden churches of the Carpathians have stood under these roofs for 200 years — without a brush, without a chemical.

01
Watertight by geometry

The shape of one shingle overlaps the shape of the next. Water runs across the surface, not through it.

02
Hail and storm proof

10 mm thick at the visible edge. A split shingle doesn't crack under impact because the fibres were already broken along the grain.

03
Roof and wall, one skin

The same shingle, the same method. The roof passes into the wall without a seam, without a change of material.

04
It ages, it doesn't fail

The wood greys evenly, the fibres close up but don't rot. After 50 years it looks better than the day it went up.

Four species
Four species of shingle

Four woods, one method.

Each wood has its reason. Oak is hard and rich in tannin. Larch lives by its resin. Spruce is light and economical. Hardened spruce is steamed to close the capillaries and extend service life.

Oak

The most noble and durable shingle. High tannin content protects the wood for over a century. For the most demanding work.

Specification →

Larch

Proven over centuries on roofs and elevations. Resin naturally protects against moisture.

Specification →

Spruce

Light and economical. Ideal for outbuildings and large areas.

Specification →

Hardened spruce

Steaming closes the capillaries, extending service life well beyond raw spruce. For roofs.

Specification →
Two profiles

Type Querc

The curved profile that raises "feathers". Specify on organic and curved buildings.

Split type

The standard method, stiffer and more irregular in texture.

From seed to roof

Flax grows in the field beside the workshop.

The same seed that gives the oil to treat our shingles blooms blue in July. Material from one place, from one year.
