Use self-adhesive foam or rubber strips on windows and doors, a brush strip under the front door, and a cover on the letterbox. Choose strips that peel off cleanly so you can remove them at the end of your lease.
Do not seal ventilation grilles or trickle vents: they are there on purpose (see the ventilation tip).
