Navy Seal Draught Shield Tape is the money-saving, energy-efficient flexible tape that seals gaps around windows and doors and goes up as easily as sticky tape! Just measure, cut to size, peel the backing and stick it where it's needed. Navy Seal Draught Shield Tape creates an airtight seal with its clever 'flex-flap' technology. It snaps right into place, stopping the draughts and cold air entering your home.JML Navy Seal Draught Shield can also be used on shower doors to prevent leaks. The flexible design lets the door open in either direction and the flex flap moulds into place keeping water in the shower where it belongs. Navy Seal is great for unfinished spaces too, like DIY projects or temporary spaces when your home is being renovated or extended. And, with three rolls in a box, you can insulate multiple doors and windows with just one pack.
