Understanding the Stone-Core Technology
The stone core changes the traditional approach from relying mainly on thickness to using a thinner but denser core. This gives Holzer Floor a more solid and substantial feel underfoot while supporting dimensional stability.
Why the core matters
What is the stone core made from?
Holzer Floor’s stone core contains a high proportion of limestone-derived calcium carbonate compounds, making up approximately 70% of the total core materials.
The stone-based composition gives the core its high density and contributes to the weight, solidity and stability of the flooring system.
How does the core support stability?
Holzer Floor’s stone core incorporates a stabilizer powder to help improve dimensional stability when temperatures change. The combination of the core’s density and stabilizer helps the flooring maintain greater stability under changing conditions.
The stone core is resistant to termite attack and contributes to moisture resistance, making the flooring system suitable for tropical and high-humidity environments when properly installed.
Important: The flooring is not waterproof. Proper subfloor preparation and moisture control are still required.
10mm vs Solid Oak Comparison: 10mm Holzer Floor has a weight comparable to approximately 22mm solid hardwood oak flooring.
| Thinner construction. Higher density. More substantial underfoot.
Why Choose 10mm?
The greater difference between our 7mm and 10mm floors is not only the thickness. We have also increased the core density of the 10mm version by over 40%, making it heavier and providing better stability.
Both the 7mm and 10mm cores incorporate stabilizer powder to help improve dimensional stability when there are changes in temperature. In general, a thicker core can provide better stability performance.
7mm: Under normal indoor room conditions, our 7mm flooring is sufficient and provides good stability.
10mm: However, the 10mm option for better stability and durability, especially because thicker core and a 2mm natural oak wear layer.
Key takeaway: Natural oak on the surface. A dense stone core underneath. Together, they create a thinner flooring construction with greater density, weight and a more solid feel underfoot — designed with tropical environments in mind.
