Solid vs engineered board: an engineer’s comparison for architects
Solid and engineered boards solve different engineering problems. “Which is better” without site context is marketing, not design.

Solid board
Homogeneous timber: sanding and refinishing depth 6–8 mm and more. Expressive grain, high tactility.
More sensitive to humidity swings — needs stable 40–60% climate and professional installation with compensation gaps.
Engineered construction
Stabilising layers reduce seasonal movement. Preferred for large areas, open plan, water and electric underfloor systems.
Refinishing depth is limited by top layer — typically 3–6 mm. High-load projects allow for local module replacement.
Site selection criteria
We assess: substrate, microclimate, underfloor heating, junction heights, load (furniture, castors, heels), service life without major overhaul.
At Cardinal Hall both types are made and installed by one manufactory — the decision is not tied to “convenient stock”.
