It is also worth noting that draughts are often caused by damaged hinges, rather than the absence of seals that are effective. The hinges are responsible for closing the window sash (the section that you open) but they can also become stiffer in time if not regularly oiled. This can create an opening between the frame and the sash, which can allow cold air to enter. Replacing the hinges can solve this issue without affecting window seals.
