 If you live in a draughty home it can be hard to stay warm without spending the fortune on your heating. But there's lots you can do to stop up the draughts, like putting a chimney balloon, up your chimney if you have an unused fireplace, or closing the gaps in floorboards with this handy V-shaped strip. To help find those draughts and to find missing insulation, did you know that you can borrow a thermal imaging camera? The thermal imaging camera makes heat visible, so you can see where the heat is leaking out from your home.
