Historical & Geological Context
Lauzes are heavy, hand-cleaved limestone or schist stone slabs historically used to roof Romanesque churches, fortified farmsteads, and châteaux in Burgundy and the Dordogne. Weighing up to 500 kg per square metre, a lauze roof requires massive green oak roof framing and is installed without mortar or nails, resting by pure gravity on overlapping tiers.
Petrographic & Geological Characteristics
Stratified jurassic limestone slabs (Laves de Bourgogne) naturally split by winter frost action.
Lime Mortar & Breathability Compatibility
Laid dry on heavy oak roof trusses with lime mortar bedding only along hips and eaves.
Provenance & Historical Sourcing
Burgundian and Périgord limestone plateaus.
Condition Report & Patina
Reclaimed from historical reroofing; sorted by size for diminishing courses.
