What's what?
Before comparing: let's clarify the materials.
Solid oak
Continuous wood. Cut into the material and you see the same grain everywhere. Comes from real trees, only sawn, planed, and oiled.
MDF (Medium-Density Fibreboard)
Wood fibres (often industrial waste) + glue + heat + pressure. Very smooth, easy to cut, very cheap. But: extremely moisture-sensitive.
Chipboard (also OSB)
Like MDF, but with larger wood chips. Even cheaper, even more sensitive.
Veneer
A 0.3–1 mm thin layer of real wood glued onto MDF or chipboard. Looks like solid wood; is actually pressboard at the core.
Lifespan in real use
We visit customers 2–3 times a year for follow-up configurations. Our observations after 3 years:
| Material | Condition after 3 years |
|---|---|
| Solid oak (oiled) | Patina developed, otherwise like new |
| Solid oak (natural) | Slightly darkened, very stable |
| Veneered | First cracks at veneer edges, occasional peeling |
| MDF (lacquered) | Lacquer chips at touched areas, occasional discolouration |
| MDF (foil-clad) | Foil peels in places, especially near radiator |
| Chipboard | Swollen corners, visible moisture damage |
Heat behaviour
Radiators reach 50–80°C. How do materials react?
- Solid oak: Excellent. Wood can store heat and re-emit it evenly. No deformation.
- MDF: Under constant heat, micro-cracks develop between fibre layers. After 5+ years often visible as waves or slight warping.
- Veneer: Layer can peel under heat + moisture (e.g. bathroom). Common failure.
- Chipboard: Very prone. We'd never recommend chipboard for a radiator setting.
Repairability
Solid oak
Scratches? Sand with grit 240, re-oil with linseed. Done. Burn mark? Sand, oil. Crack? Fill with wood glue, sand, oil. Everything is fixable — even after 20 years.
MDF, veneer, chipboard
Once the surface is damaged (lacquer chipped, foil torn, veneer sprung), the damage is permanent. Re-lacquering rarely works convincingly. For deeper damage: replace.
Environmental impact
| Material | CO₂ per piece | VOC emissions | End of life |
|---|---|---|---|
| Solid oak | ~12 kg | None | Compostable, repairable |
| MDF | ~47 kg | Formaldehyde | Hazardous waste, hard to recycle |
| Veneer on MDF | ~42 kg | Formaldehyde | Hazardous waste |
| Chipboard | ~38 kg | Formaldehyde | Hazardous waste |
Value retention
- Solid oak: Value-retaining, sometimes appreciating. Antique oak furniture is worth more today than at purchase.
- MDF / veneer: Value loss of 80–100% within 5 years. Often binned when moving.
The price question
A solid oak cover costs 2–4x more than MDF. But:
- It lasts 3–5x longer
- It retains its value
- It's healthier
- It's aesthetically unbeatable
Cost per year, solid oak often comes out cheaper than MDF.
Invest once — not every 5 years.
