FREQUENTLY ASKED QUESTIONS ABOUT DRAUGHT PROOFING

What is a draught? Draughts are most commonly identified on windy days, when the external cold air penetrates the fabric of the building, thus displacing the warmer internal air causing noticeable discomfort. On non windy days where the internal pressure of the building is higher than the external pressure the warm air escapes through the fabric of the building causing heat loss, this is less noticeable but wastes valuable energy.
Where are the most common draughts found? The most common place for draughts are around the frames of external wooden doors and windows. This is usually caused by either poorly fitting doors or windows, or seasonal variation. This is when the timber expands or contracts depending on the moisture content. Other areas where draughts can be found are between the frames of doors and windows and the brickwork, also under the window sills. They are also found where services or waste pipes come through the walls of a building.
How can I tell if there is a draught? The easiest way to identify a draught is by wetting the back of your hand and passing it over the area where you suspect a draught may be, there should be a noticeable difference in temperature when a draught is felt. Alternatively draughts can be identified by a professional who may use a smoke pencil or match.
