If you follow the smoke trail and pay close attention to the floorboards, doors and windows, you’ll be able to easily identify the main source of draught.
Martin Troughton, Marketing Director at Safestyle explained: “Older windows tend to let a lot of the precious heat from your home escape meaning that you’re using more energy than you probably need to when heating each room.
“Energy-efficient windows, on the other hand, will not only make your home feel warmer and save you money on your energy bills, but it will also help to reduce your carbon footprint.
“However, it’s not only old windows that can have a negative impact; if your windows are poorly installed and maintained, then this can also be problematic.
“It’s really important to keep up the maintenance of your windows as failing to do so could actually cost you a lot of money in heating bills.”
