Draught Proofing Windows and Doors

You may be losing as much heat through the gaps around your windows as you are through the fabric of the window itself. Cutting out these draughts is a relatively straight-forward way of reducing heat loss and improving your comfort within the room.

Many traditional timber windows are draughty and difficult to operate because of the effects of wear and tear over the years, including warping due to moisture movement and the accumulated impact of repainting jobs. If your windows do not fit very well, or are difficult to use, consider having them professionally renovated. Draught-strips and brushes can then be fully integrated into the windows as part of the renovation.

Even if your windows do not need renovation, the most effective and discreet draught-proofing systems are those which are professionally installed and integrated into the fabric of the windows. These systems both reduce draughts through the windows and improve levels of soundproofing. There are, however, DIY options available at lower cost.

Draught-strip comes in many shapes and sizes, so it’s important to find the right strip for each job. Ideally, you want draught-strip that is the same colour as your window, sits discreetly on or within the frame or on the window itself and provides an effective seal when the window is closed. For casement windows, compression or brush strips can be used at the junction of the window panes or where the edge of the window closes against its frame. For sash windows, brush strips are usually installed around the window and at the horizontal junction of the two panes.



A great deal of cold air is also admitted, and a great deal of warm air lost, through front and back doors. If your home has a draught lobby – an inner door to protect the house when the front door is open – take care to close the inner door before you open the outer door (and vice versa). Draught-proofing products for doors include compression and brush seals for the edges, keyhole caps and letter box covers. Cumulatively these simple measures can make a huge difference to the comfort levels within your house, and your bills.
