This feature also improves accessibility, making it ideal for homes, offices, bedrooms, or busy commercial spaces.

It’s also highly effective for acoustic insulation, blocking out hallway or street noise, and reducing unwanted light leaks—perfect for bedrooms, studies, or shared living areas.

Review: Works perfectly - Brilliant idea works flawless
Review: An excellent way to stop draughts - We've previously had mechanical draught strips that dragged on the floor and eventually stopped working. This is much better is you hide it in a channel that you rout into the bottom of the door. It's an easy DIY job with just a few screws once the groove has been cut in the bottom edge of the door. The button that releases the seal can be adjusted to suit your door jambs so it drops down and seals at just the right point Our hallway is now noticeably warmer, and I'll be buying a second one soon for the back door too.
