foam sealing vs gap

foam sealing vs gap

Is there any practise around using foam when installing doors/windows ? Historically, that space was left as is to allow for expansion and contraction. However, in this age that just seems irresponsible especially when it comes to efficiency and heat retention. Expansion foam is the obvious solution but then how does that effect expansion/contraction of the window/door ?
