Windows are a major source of heat loss in the home so when the cold spell hits, try to reduce this by blocking out windows with well-fitted thermal curtains.

In older homes, windows are areas of significant heat loss. Poor seals, gaps, loose panes and even the thickness of the glass can all be factors.

Double glazing will greatly improve things but is not an affordable option for everyone. Decent curtains can help. Fitting is a key issue – even lined, thermal drapes made from heavy fabric will be less efficient than lighter drapes that fit properly.

Heavier fabrics ensure a better fit but cheaper fabrics lined with a good backing material can be made to achieve a similar thermal effect.

For optimum performance drapes should be larger than the window, extend down to the floor and be enclosed at the top by pelmets – this will minimize air movement between the glass and the curtain.

Once the practicalities of covering the windows are under control, you can consider the aesthetics.

Drapes work best when they are chosen to match the style of the room. The choices of colours, textures and styles are endless.

Opulent rooms suit extravagant window dressings while contemporary, minimalist styles require understated drapes.

European trends are leaning towards luxurious textures, rich velvets and linens with metallic overlays.

Alternatively, there are many ready-made versions on the market which come in a comprehensive range of prices, and in sizes to suit most standard windows.
