Use vinyl "V' strips between the sash channels and the sash stiles on double-hung windows that have sliding windows. Make sure the strips fit snugly against both sides of the channel to form an airtight seal when the sashes are closed. For casement windows that sit on a hinge and have to be opened with a crank, you can apply foam tape to seal the top, bottom and side of the window stop.

Foam tape is cheap and less than a dollar for a foot, and is easy to install. It's suitable for gaps that are up to an inch wide. If you want a more durable and stronger sealer for gaps larger than an inch wide, try EDPM (ethylenepropylenediene monomer) or all-wool felt.

Some have anti-fungal ingredients to prevent the growth of mold and mildew.

Another reason why window seals could fail is because they are exposed to extreme temperatures and changes in humidity. The seals can expand and contract as a result.
