Can a draft through a window or door cause damage? It can. Damage to your bank account! A single, seemingly minor, draft through a window can increase your energy bill by as much as 3%. In addition, a damp draft can make a room feel colder than it really is, while a dry draft can cause dry throats and skin.
So it pays to pay attention to drafts in your home.
Drafts are most commonly found at windows and doors, but they can also occur through walls with poor or old insulation.
Ideally, a draft should be eliminated through a repair or renovation (such as replacing old windows.) When that's not possible, there are a variety of products available that will help you stop drafts in the short term – such as replacement insulation strips for doors.
