Homogeneous or heterogeneous vinyl for healthcare
2026-10-25
Both are called vinyl flooring in the submittal. They behave differently when a ward is in use, and the difference is not visible in a sample book.
What the two constructions actually are
Heterogeneous vinyl is a printed design layer covered by a transparent wear layer. It gives you hundreds of patterns and a lower price per square metre.
Homogeneous vinyl is the same composition through the full thickness. Wear exposes the same colour and pattern, so a scratch or a deep clean does not reveal a white core.
Why hospitals moved to homogeneous
In a clinical area the floor is cleaned with aggressive chemistry, moved over by trolleys and beds, and cut by the occasional dropped instrument. A printed layer under a thin wear film shows that history.
Homogeneous sheet can be welded into a continuous surface, and it can be refurbished by stripping and re-polishing rather than replacement — which is the difference between a maintenance budget and a capital project.
The compliance numbers to ask for
Our homogeneous range is screened to the EU 249 list of hazardous substances: free of 19 heavy metals and 60 phthalate plasticisers. Ask for the screening report, not a statement of compliance.
Wear class T, slip R9, fire B1. In wet areas the slip class is the number that ends up in an incident report, so it should be tested, not assumed.
When heterogeneous is the right answer
Where the design intent is a specific pattern — a school corridor, a retail floor, a hotel lobby — heterogeneous gives design freedom at a lower cost, and replacement of a damaged tile is cheap.
For back-of-house areas with light traffic, it is often the sensible choice. The mistake is specifying it for wards and theatres because the sample looked good.
| Property | Homogeneous | Heterogeneous |
|---|---|---|
| Construction | Same through thickness | Printed layer + wear layer |
| Wear appearance | Colour holds | Printed layer can show through |
| Welding | Full seam weld | Weld at edges only |
| Refurbishment | Strip and re-polish | Replace |
| Design freedom | Limited palette | Wide |
| Typical use | Wards, theatres, labs | Corridors, retail, classrooms |
FAQ
Is homogeneous more expensive?
Usually yes on material cost, and usually cheaper on lifecycle cost in a clinical area because it can be refurbished rather than replaced.
Can both be welded?
Both can be welded at the seam, but only homogeneous keeps a consistent face when the surface is worn or stripped.
What about static?
Ask for the conductive or dissipative variant if the area requires it — it is a separate product, not an add-on.
