Fallen leaves and crisp fresh air is a sure sign winter is right around the corner. This year instead of dreading the cold months, take action and enjoy your winter! One of the easiest and cost effective ways to do this is through window coverings. An estimated 10 to 25% of heat is lost through windows. Window coverings will keep you warm, save you money and even cut your carbon usage.

Thicker is Better
Curtains act as insulation for your windows, similar to an extra blanket on your bed, a thick curtain on your window will keep you warmer. Drapes with lining are your best bet as cool air gets trapped between the layers. This also occurs with closely woven fabrics, trapping cold air in the weaving.

Tight is Right 
When combating cool air, think about the edges. Tight fitting blinds leave few gaps for cold air to enter. Your ideal covering is a tight fitting, floor length heavy curtain.

Curtains which come to the floor will insulate the entire window surface, acting as a barrier to prevent cold air circulating through the house. The more snug the fit the better. Tight fitting offers the same insulation, but more compressed. Many window coverings now attach on side rollers, literally sealing off the window, additional water trim on the bottom creates the perfect seal.

Window Shutters
Window shutters operate with the same sealing technique as curtains. When closed they form a thick wall to prevent heat loss, and are easily opened to allow for sunshine through the day. Esthetically pleasing they offer a clean and controlled look to your room, just remember if you want to get the most out of them, makes sure the fit is precise.


  • Sunlight is free. Open south facing window curtains to capture sunlight through the day and warm your home naturally. Conversely, windows which do not receive direct sunlight should be covered, especially at night.
  • Work with what you have, if you have horizontal blinds, keeping the inside edge closed upwards is another free way to keep heat in and cold out.
  •  Make sure if curtain fabric is reaching the floor it is not in contact with any hot air vent, or any other fire safety hazard.
