Let's say you have 15m long corridor in wooden house and you need sprinkler system along the corridor. If you have temperature increases 30C that may cause your sprinkler system to now be 5mm longer than it was before in relation to the size of the house. Now we could have suspended the sprinkler pipe to the roof so that every suspension point allows 1mm sliding movement. Or we could have replaces 1 meter section of the pipe with hydraulic hose and leave it slightly bent. Doesn't sound like an issue really.
