How to winter-proof your sash windows

As energy bills are rising, and temperatures are dropping, you might be thinking about ways you can make your home more energy efficient. One of the things you might want to think about is your sash windows. While floors, walls and attics can be easily insulated against winter heat loss, windows are one of the biggest culprits of causing icy homes. Here are some of the ways you can winter-proof your sash windows…

Hang thermal curtains

Thermal curtains are a great way of retaining warmth in your rooms. They form an insulated barrier against cold windows, trapping old air between the glass and the window, preventing it from entering your home. If you want to make the most of the sun (on those days it’s out), don’t forget to open your curtains on sunny days so the heat can shine into your house.

Reseal your windows

Even a quick whip around with caulk can make a huge amount of difference when it comes to winter-proofing your sash windows. Keep an eye out for thin cracks or gaps around the edges of your window joints and caulk these to prevent icy drafts from flowing into your rooms. If you are looking for a more permanent solution, gaps around your windows may indicate you are in need of sash window repair.

Apply a temporary window film

A window insulation film is made of thin, transparent plastic (quite like cling film), which is applied to windowpanes before being heat shrunk using a hairdryer. This creates a close fit around the windows that can be useful for draught-proofing windows in winter.

Upgrade your sash windows

Naturally, the ultimate way to winter-proof windows is to upgrade them to double-glazed timber units, which are specially designed to keep the heat in your home. Double glazing works with the air itself which acts as a poor conductor of heat, trapping an insulating blanket of air between the panes of the glass. This layer of air acts as a barrier, keeping your home warm.
