Is engineered wood real wood?

Yes. The surface you walk on is genuine oak, typically 2 to 6 mm thick, bonded to a stabilising core. Once fitted it is visually and underfoot identical to solid oak.

Which lasts longer, solid or engineered wood?

Solid wood can be sanded more times, so its ultimate ceiling is longer. In practice an engineered floor with a thick wear layer serves 30 years or more with one or two refinishes, which outlasts most owners’ style preferences.

Why is solid wood not recommended with underfloor heating?

Heating cycles dry single-piece timber unevenly, causing shrinking, cupping and gaps. Engineered boards keep the oak surface flat through those cycles and are the manufacturer-approved real-wood route over UFH.

Is solid wood more expensive than engineered?

Often not any more. Comparable specifications overlap heavily, and engineered frequently comes in cheaper once faster fitting and simpler subfloor preparation are counted.

Solid Wood vs Engineered Wood Flooring: The Honest Comparison

Same oak on the surface, completely different behaviour underneath. Why construction decides where each one belongs.

Solid

One piece of timber

Engineered

Oak over a layered core

Underfloor heating

Engineered only

Structural warranty

25 years

The only difference that matters

Solid wood is one piece of timber all the way through. Engineered wood is a real oak wear layer bonded to a core whose layers run at right angles to each other.

On the surface they can be indistinguishable. Underneath, the cross layered core restrains movement, and that restraint is what decides which rooms each floor can go in.

Not a quality question: Engineered is not a lesser version of solid. It is a different construction that solves a specific problem, and in a modern home it usually solves it better.

Where they differ in practice

Five differences, and they all trace back to the core.

Movement

Solid moves most across its width through the seasons. Engineered holds its width.

Underfloor heating

Solid is not suitable. Engineered is. This is the decisive point in most modern homes.

Board width

Wide boards are normally engineered, because a wide solid board moves too much.

Fitting

Solid is usually nailed to a timber subfloor. Engineered can be floated, glued or nailed.

Refinishing

Solid can be sanded many times. Engineered can be sanded as far as its wear layer allows.

Which suits your home

The building usually answers this before taste does.

Underfloor heating

Engineered. There is no version of this where solid is the right answer.

Concrete subfloor

Engineered, glued or floated. Solid wants timber to fix into.

Period property, timber joists

Solid is at home here, and it is the traditional detail.

Wide boards

Engineered, for stability across the width.

Living with each

Both are real wood, so the care is the same. What differs is what happens in twenty years.

Same daily routine

Sweep often, damp mop rarely, felt under furniture, mats at the doors.

Same seasonal movement

Fine gaps in winter that close in summer. Larger on solid than on engineered.

Refinishing

Solid gives you more future sandings. Engineered gives you as many as the wear layer allows, which is usually enough for a domestic life.

The guarantee

Our floors carry a 25 year structural warranty under normal domestic use and correct installation.

Important: Fitting solid wood over underfloor heating falls outside the guarantee, and the floor will move whatever the fitting method.

What the published standards say

Each entry is quoted from its source and linked to it. The full set is in the standards reference.

BS EN 13489 — multi-layer parquet

BS EN 13489 is the product standard for multi-layer parquet elements, setting out their characteristics, requirements and test methods for internal use as flooring.

“This document specifies the characteristics, requirements and test methods of multi-layer parquet elements for internal use as flooring.”

BS EN 13226 — solid parquet elements

BS EN 13226 specifies the characteristics of solid parquet elements with grooves and/or tongues intended for internal use as flooring, covering elements with or without surface treatment.

“This European Standard specifies the characteristics of solid parquet elements with grooves and/or tongues for internal use as flooring. This standard is not applicable to panels made from elements for which a separate standard is in course of preparation.”

Maximum floor surface temperature

EN 1264 caps the floor surface temperature at 29 °C in the occupied area, 35 °C in the edge (perimeter) zone and 33 °C in bathrooms.

occupied area	29 °C
edge zone	35 °C
bathrooms	33 °C

“Max. surface temperatures in DIN EN 1264: • 29 °C in the occupied area • 35 °C in the edge zone • 33 °C in bathrooms”

Wood over underfloor heating

UK trade-association guidance sets no blanket ban on wood over underfloor heating but ties it to a temperature limit, noting that some hardwood floor finishes are installed with a maximum floor surface temperature of 27 °C.

How often a wood floor can be sanded

No trade-association or standards source found puts a number on how often an engineered wood floor can be sanded; the only sourced figure comes from a manufacturer, Kährs, which says engineered floors can be sanded up to four times depending on wear-layer thickness.

sanding cycles, engineered wood floor (manufacturer statement)	up to 4 times

“Depending on the thickness of the wear layer, they can be sanded up to four times, extending their lifespan significantly.”
