Doorway draughts are unwelcome at any time of year, especially during the winter months when heat is precious. Making sure your home is well-insulated against draughts is an important part of reducing your energy consumption and lowering your heating bill. There are several ways you can stop draughts from your doors, varying in price and overall effectiveness. The exact method you choose will depend on the location of the draughts in the doorway and your budget.
Purchase a soft draught excluder to lay at the base of the door. These long, thin, plush furnishings are filled with beans or other weighted material to block out small draughts in exterior or interior doors. They work simply by covering the draught and are generally affordable. Soft draught excluders come in a variety of styles and look tidier than simply laying a blanket or towel at the base of the door.
Fit a adhesive draught excluder to the door frame. These do not require any expertise to fit. Adhesive draught excluders work when fitted to the inside of the doorframe, creating a tight seal between the cold outside air and the warm air inside. These draught excluders are a more permanent solution than the soft draught excluder.
Screw a draught excluder brush strip to the base of the door. Used mainly for exterior doors, these smooth, flexible brush strips prevent drafts of air slipping underneath the door. Similar brush strips are sometimes fitted inside letterboxes to prevent a cold rush of air when the mailman deposits the mail. Though effective, you can affix brush strips only to the base of the door.
