Winter is right around the corner and while you may be excited about the cold weather, your office windows aren’t. The average window will transfer 30% of indoor heat to the frigid outdoors, forcing your heater to work overtime and costing you money. Luckily, there are some simple things you can do to prepare your office windows for cold temperatures.

Draught Excluders

Whether homemade or store-bought, a draught excluder is a simple way to reduce airflow at your windows. Simple rolls of foam, brush, or fabric can be attached to the bottom and top cracks of windows to stop warm air from escaping. There are also a variety of sand or rice-filled options, often shaped into whimsical animals and decorative pieces, designed to sit at the bottom of the window. Unfortunately, this does nothing for the heat loss occurring through your window panes.

Seal Gaps

Even triple-glazed windows won’t keep heat in if there are cracks around the window or frame. For a quick fix, pack gaps with cotton balls, felt, or foam and cover with duct tape. For a more professional and long-lasting solution, re-caulk around the window frame where it meets the wall. Gaps between the frame and the window itself may be corrected with new weather stripping.

Plastic Coverings

Plastic coverings and window films have long been used in residential homes to help retain heat in the winter and they can work equally well for businesses. These kits usually contain double-sided tape and plastic sheeting. You will need a hair dryer to bond the plastic to your windows. This option can reduce heat loss by 50% or more, but it takes valuable time to install and can look very unprofessional if you have clients visiting.


The amount of heat loss through your windows has a lot to do with its glazing. Double-glazed windows feature two panes of glass sealed together with a tiny layer of air between. This air layer reduces heat conduction and can result in 54-64% less heat loss as compared to single-glazed windows. Installing new double or triple-glazed windows could be well worth the cost savings on your heating bill, but this won’t be the best option for everyone.

Blinds & Window Treatments

Perhaps the best option for prepping your windows for winter is to invest in blinds and window treatments. Modern shades, particularly honeycomb-shaped shades, are designed to increase energy efficiency while maintaining style. Shades and window treatments provide better insulation and look better than window films or heavy curtains. Sheer shades can also let in daylight while simultaneously reducing air flow at your windows. An energy-efficient window treatment is your best option for winterizing your windows.

If you want to reduce heat transfer at your windows and save energy and money in the winter, it’s important to prep your windows for colder temperatures. Whether it’s a simple draught excluder or a brand new, professionally designed commercial window covering, you can make a difference to your office temperatures.
