Rear ventilated façade / Rain screen cladding installed onto exterior thermal insulation

The design principle involves the deflection (screening) of the rain water. As the panel joints are not sealed, minimal amounts of water can gain access into the air cavity behind the panel. The cavity is naturally ventilated by vent gaps at bottom and top, so that any moisture will evaporate naturally by thermal action. Cladding systems that are sealed on the exterior do not allow any moisture to evaporate; thus leaks will lead to problems like mould, fungi, etc. on systems without rear ventilation.

Advantages
  • Almost no maintenance
  • Maximum thermal insulation effect, without thermal bridges, keeping the building structure at a constant temperature; humidity / condensation is eliminated.
  • Considerable energy savings
  • No cracks, sealant, paint problems

  1.  Cladding panels
    Shield off the weather. The cladding panels are crucial for the appearance of the building. The panels are attached to vertical supports by rivets, screws or concealed fastening system.
  2. Vertical panel supports I Air cavity
    Made out of metal profiles or timber battens.
  3. Exterior thermal insulation
    Material, thickness and attachment to be determined by architect; including vapor/moisture barriers as required.
  4. Exterior wall
