Which wood species do you use for parquet?+
Oak, ash, walnut, maple, cherry, teak, merbau, wenge and more — 40+ species. Species, grading and finish are fixed in the specification before production.
What is Select, Nature and Rustic grading?+
Select — calm grain, minimal knots. Nature — natural variation. Rustic — character: knots, contrast, sapwood. Grading shapes look, not strength alone.
How do I choose solid vs engineered construction?+
Solid allows deeper refinishing. Engineered (2–3 layers) is more stable on large areas and often suits underfloor heating. Both are covered here; engineered landing: /catalog/parquet/engineered-board.
Oil or lacquer finish?+
Oil — tactile feel and spot repair. Lacquer — higher wear resistance. Tinting, brushing and thermo are also available — matched to care and room load.
What does one timber batch mean?+
Floor, kitchen, doors and panels from one species and grade lot — tone matches now and years later.
How is this different from the interior wood species catalog?+
This page is floor material: constructions, grading and parquet finish. Kitchens, doors and furniture species: /catalog/wood-species.
What is Cardinal Hall's single-batch wood concept?+
One wood lot for the entire interior — floor, doors, kitchen, stairs — identical tone for decades.
How long does Cardinal Hall dry timber?+
280 days of chamber and thermobaric drying. 6–8% moisture, ±0.5 mm geometry.
