A home heating expert has revealed a genius £1 winter hack to keep the warmth in – and all you need is bubble wrap and a splash of water. As temperatures drop and energy bills rise, homeowners seek affordable ways to keep warm. One clever method uses bubble wrap and water on windows to trap heat.
Jennifer Shaw from Plumbworld recommends this simple yet effective approach: “The hack is straightforward and uses materials you likely already have or can find for a small cost. Bubble wrap is a surprisingly effective insulator, helping to reduce heat loss by trapping a layer of air in its bubbles. The best part? All you need is bubble wrap and a little water.”
How to use bubble wrap to insulate your windows
Cut to size: Begin by cutting the bubble wrap to the size of each window. For the best fit, measure the window panes and cut the bubble wrap to match the dimensions closely.
Apply water to the window: A simple misting of water is the key to getting bubble wrap to stick to windows without tape. Using a spray bottle, lightly spray water directly onto the windowpane.
Attach the bubble wrap: Press the bubble side of the bubble wrap against the wet windowpane. The water will act as a natural adhesive, keeping the bubble wrap securely in place.
Smooth it out: Use your hands to smooth out any air bubbles and ensure the wrap is flush against the glass. This step helps create a tight seal, which is crucial for keeping the cold air out and the warm air in.
Reapply as needed: It’s worth checking periodically to make sure the bubble wrap remains in place, particularly if it loosens over time. If needed, simply reapply a bit of water and press the wrap back onto the glass.
Why bubble wrap works
Jennifer explained that bubble wrap works well as a temporary window insulator due to its air-trapping ability. “The bubbles act as a barrier that helps reduce the transfer of cold from outside, keeping warmth inside your home,” she said.
While it may not match the insulation of double glazing, she calls it “a practical alternative for those looking for a low-cost solution that still makes a difference”. Highlighting its cost-effectiveness, she notes that you can pick up a roll of bubble wrap at Wilko for just £1.
Jennifer also points out how easy it is to use and remove. She said: “One of the great things about this hack is that it’s fully reversible and doesn’t leave any residue. When the weather warms up, simply peel off the bubble wrap, wipe down the windows, and store it for next winter.
“Sometimes the simplest methods are the most effective. Keeping the warmth in doesn’t have to be complicated or expensive.”
