Our draught excluder strips are self adhesive so are easy to fit but we highly recommend that you drill through the strip into the door and affix with additional screws (not included). They help keep the heat in your home and can help prevent up to 35% less heat loss so will help you become more energy efficient. Approx. 100cm wide, enough for a standard door but can easily be cut to fit your door width. The height of the bristles from the strip is approx. 20mm and the total height is approx. 45mm. Manufactured from PVC and are available in white or brown, simply choose your colour from the drop down menu.
