The simple solution to draughty floorboards. Each pack contains 40m of StopGap and can be easily fitted without the need for glues or screws. A simple way to get warmer heat and lower bills. The strip is folded into a V and then pressed between the floor boards using a credit card (or similar) on the joists. Simply cut to length. Will fill gaps between 1mm and 8mm (thickness of a pencil). Can be removed and replaced as required (so can be used on sash windows over winter). Reduces all the problems associated with gaps - noise, draughts, insects, light and smells.
