In winter, drafts can significantly impact how well we heat our homes.

Experts suggest a simple adjustment can reduce heat loss by up to a third, taking just moments to complete.

Here's how switching your windows to 'winter mode' effectively weatherproofs your home during chilly months.

Understanding 'Winter Mode' for Windows

To learn about 'winter mode', we consulted specialists who clarified that many modern windows feature an adjustable setting. This allows you to tighten the fit of the window within its frame.

This adjustment, recently termed 'winter mode' on social media, effectively minimizes cold drafts.

'Adjusting your windows to winter mode is quick; typically under a minute per window using a standard Allen key,' says Geoff Clarkson, a window installation expert. The Amazon Basics Hex Key Allen Wrench is all you need.

'You only need to do this once before the cold sets in; it's easily reversible in spring,' Geoff adds, when it's time to keep your home cool.

Steps to Set Your Windows to 'Winter Mode'

Putting your windows in 'winter mode' takes minimal time and helps save on heating costs.

Start by opening your windows and locating small screws on the inside of the frame, which typically fit an Allen key and have a notch pointing to 12 o'clock.

Insert the Allen key and turn the screw clockwise a quarter turn. This pulls the window closer to the frame, sealing gaps and effectively draft-proofing any room. After adjustment, the notch should point to three o'clock.

'Check the fit after closing the window,' advise the experts. 'If it feels stiff, ease it slightly by backing the screw until the notch is at one or two o'clock. This avoids over-compressing the rubber gaskets, preventing damage over time.'

Though it takes mere seconds, this adjustment can significantly cut your energy costs during colder months, especially in older homes.

'Windows can account for 10 to 15 percent of energy loss,' Geoff explains. 'Tightening the seal reduces drafts and keeps warmth inside.

'While this won't replace good insulation, it can reduce heat loss through gaps by up to a third.'

Layering curtains offers an effective solution to block drafts.
