How to Choose Oak Parquet Flooring Thickness

Oak parquet is available in thicknesses from 12 mm to 22 mm, but the "best" thickness depends on your project — not on picking the largest number. This guide walks through the questions that determine the right thickness for your floor. For full technical specifications and the complete size range, see our Solid Oak Parquet Dimensions Guide and Engineered Oak Parquet Dimensions Guide.

Why Thickness Matters — Beyond the Number

Floor height. Every millimetre of board thickness adds to the finished floor height — important in renovations where door clearances and transitions to other rooms are fixed.

Refinishing over time. Thicker solid oak boards (22 mm) can be sanded and refinished more times over their lifetime than thinner boards. If you're planning for 50+ years, thickness becomes a long-term investment, not just a spec.

Underfloor heating compatibility. Thickness directly affects heat transfer. Engineered oak at 12 mm total thickness is the only option that combines comfort underfoot with efficient heating performance — solid oak and thicker engineered boards are not recommended for heated floors.

Frequently Asked Questions

What oak parquet thickness should I choose for underfloor heating?

For underfloor heating, choose engineered oak parquet with a total thickness of 12 mm. Its stable plywood core conducts heat efficiently and resists gapping, unlike solid oak.

Is a thicker oak parquet board always better?

No. Thicker boards allow more sanding cycles over time, but they also raise the floor level, cost more, and are not suitable for underfloor heating. The right thickness depends on your project, not on choosing the maximum available.

What thickness is best for a renovation with limited floor height?

For renovations where floor height is limited, engineered oak parquet at 12 mm total thickness is the best option — it is thinner than solid oak while remaining durable and suitable for underfloor heating if needed.
