Querc
Construction timber
Graded structural timber, available in 3–6 m lengths.
A roof that outlives the people who build it.
We split oak, larch and pine 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.

Water has never found a way through a feather.
Splitting along the grain preserves the wood's continuous fibres and closed capillaries. Each shingle lies flat over the next, and each gives water downward because there is nowhere to draw it in. Wooden churches in the Carpathians have stood beneath such 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 its continuous fibres follow 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 woods, one method.
Each wood has its reason. Oak is hard and rich in tannin. Larch lives by its resin. Pine is light and economical. Hardened pine 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 →Hardened pine
Steaming closes the capillaries, extending service life well beyond raw pine. 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.
Also from the same oak
Oak cobbles
Oak mosaic cobbles — for patios, paths and floors. The same material, the same selection as the oak shingle.
