Cladix wall cladding is installed on a timber frame or a aluminium support structure. That choice determines how stable, safe and low-maintenance your facade will remain in the years to come.
Let's put wood and aluminium side by side for a moment.
Timber support structure for facade cladding
A timber support structure feels familiar. Yet it scores less well as a substructure for modern cladding.
Disadvantages of a wooden support structure
- Combustible: it increases fire risk.
- Sensitive to moisture: risk of rot and infestation.
- Works with temperature differences: may warp or deform.
- More maintenance needed: requires follow-up over the years.
- Limited lifespan compared with aluminium.
Wood is alive. And that sounds romantic, but behind your facade, you want stability above all.
Aluminium support structure for facade cladding
We resolutely opt for an aluminium support structure. It offers stability, fire safety and a long service life without surprises.
Advantages of aluminium as a support structure
- Fireproof
- Do not rot
- Does not warp
- Resistant to moisture and weathering
- Light but extremely strong
- Low-maintenance
Aluminium stays. No operation, no deformation, no headaches.
Wood vs aluminium support structure
| Wood | Aluminium | |
|---|---|---|
| Fire safety | Combustible | Non-combustible |
| Stability | Sensitive to operation | Form-fitting |
| Sustainability | Prone to rot | Very long lifespan |
| Maintenance | Regular monitoring needed | Minimal maintenance |
| Renovation | Less flexible | Perfectly adjustable |
Aluminium offers more security, less maintenance and a longer lifespan.
RGL8 aluminium support structure
Cladix perfectly matches the aluminium support structure RGL8 from Backforce. This adjustable system makes facade projects faster, more accurate and safer.
What is RGL8?
RGL8 is an adjustable aluminium support system for residential construction. You work to millimetre accuracy, even on uneven walls.
- Adjustable: easily adjust the distance between supporting wall and facade, ideal for renovations or non-level substrates.
- Perfect alignment: the combination of lightweight aluminium profiles with a plastic rule set and smart fastening components ensure exact alignment of your profiles, after installing your insulation.
- Easy placement: its compact and adjustable design makes it particularly practical and ideal for private facade projects up to three storeys high.

Why Cladix on aluminium?
Combine Cladix cladding with the RGL8 aluminium support structure and you get:
- Maximum fire safety
- Tight alignment
- Long service life
- Low maintenance
- Suitable for new buildings and renovations
