Thermal expansion

Thermal expansion depends on surface temperature, thus on the colour of the surface treatment.

Maximum temperature increase of the outer surface is:

  • Anodized natural surface: approx. 30°C.
  • Thermolacquered ‘not white’ surface: up to 70°C.

Thermal expansion of aluminium elements used in facades is empirically admitted to be approx. +/-1.2 mm/metre for a temperature difference of 100°C. This order of magnitude is also valid for Profile Design System cladding.

In practice, following principle is agreed upon:

  • Installation should take place at a temperature of 20°C.
  • Expansion at a temperature of −10°C for profile length of 3m: −2 to −3 mm.
    profile length of 6m.: −5 to −6 mm.
  • Expansion at a temperature of +70°C for profile length of 3m: +2 to +3 mm.
    profile length of 6m.: +5 to +6 mm.

For profile lengths of 3 metres an expansion joint of 2 to 3 mm is thus required, for profile lengths of 6 metres, the expansion joint shall be 5 to 6 mm.

Recommendation for the installation of large elements:

  • Fixed point to be located near the angles of the building; oval shaped holes for the other anchor points.
  • Fixed point to be located in the centre of the profile; oval shaped holes for the other anchor points.

Manufacture and installation

  • Easy to implement, with self-tapping screws.
  • Numerous applications in buildings (internal or external).
  • No visible anchor points.
  • Recyclable.
  • Standard length: 6,000 mm. Special lengths upon request.
  • Recommended surface treatment: Thermolacquered according to QUALICOAT standard. Anodization possible with definition, prior to execution, of minimum and maximum colour tolerance (light – dark) according to QUALANOD EURAS EWAA standard.
  • Prohibited contact: Non protected steel or steel covered with a paint containing lead, copper, iron or mercury. During installation, any projection of mortar or cement as well as welding or grinding debris shall be avoided. Also, specific types of wood: oak, chestnut tree and wood treated with products containing metal brass oxides, copper, tin or lead.
  • Drainage of surface water: As for all ventilated facades, some humidity is admitted in the ventilation air layer. The drainage is provided for by adequate machining of the U, L or T shaped aluminium joining profiles.
  • Maintenance of Profil Design System: Maintenance mainly consists in washing the facades with soapy, non alkaline water. It is recommended to perform outside surface maintenance every second year. In the conception phase, the project manager will make sure to select a profile in the PDS range that facilitates maintenance in vertical or horizontal applications.
