This is the UK's Number 1 Draught Excluder. Simply because of the numerous benefits for having one on each door in your home. The Draught Buster is a unique patented design that simply slides on the bottom of the door and stays in place on the door. Unlike the draught snakes that need putting back in front of the door every time you open the door & the flimsy foam draught excluders, the Draught Buster fits the door and moves with the door. The Draught Buster will fill gaps underneath the door up to 15mm (0.6") and will adjust to fit smaller gaps. Also it will move up to go over door plates and bumps in the floor. It can be fitted to any standard interior door up to 30" in length and can be cut down to fit any door smaller that that. The Draught Buster has many benefits and heres just a few: • Saves money - energy bills reduced •Insulates rooms - keeps warmth in & draughts out •Fitted in seconds - no tools or fixings required, simply slide under the door & leaves no residue from sticky glue •Moves with the door - no need to reposition •Automatically adjusts - can fill gaps up to 15mm (0.6") and adjust over door plates •Works on all interior floor types - carpets, wood, tiles, linoleum & more. •Blends into decor - simple, discreet design •Blocks sound & smells - sounds & smells are reduced •Barrier to spiders & crawling insects - helps to prevent entry. Size approx: 76 x 4.3 x 3cm (30 x 1.7 x 1.1") One of the main problem with the draught excluders that are not fitted is that they pose a tripping hazard when not up to the door. The Draught Buster completely eradicates this problem leaving your home safer, warmer, free from pests and energy efficient.
