Should I choose a wooden or aluminium load-bearing structure?

Are you hesitating between a timber or aluminium support structure for your facade? We clearly list the differences and show why aluminium is often the stronger choice.

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.

Aluminium offers more security, less maintenance and a longer lifespan.

RGL8 aluminium support structure

What is RGL8?

RGL8 is an adjustable aluminium support system for residential construction. You work to millimetre accuracy, even on uneven walls.
