Description

After a great summer with lots of sun, now is a good time to consider the impact the sun and higher temperatures have on a building’s cladding.

All materials move in response to temperature changes – some significantly more than others. The hotter or colder a material gets, the more movement there will be. Other factors that influence the amount of movement are:

  • daily temperature range
  • material – for example, steel expands and contracts more than timber but less than aluminium
  • the amount of insulation behind the cladding – material surface temperatures will be higher where insulation is fitted tightly to the back of the cladding
  • colour – darker-coloured materials get hotter so will expand more when heated
  • orientation – north and west-facing materials get hotter and move more than those facing south
  • potential shading
  • cladding (panel) length – the longer the element, the greater the expansion and contraction that must be accommodated.
