solUtion 1: add film

if you have single-glazed windows and don’t want to pay for doubleglazing, there’s a cheap alternative. specialist window film can be fixed to the frames with tape, heated with a hairdryer and shrunk to fit. the layer of air trapped between the window and the film will provide insulation, helping to keep your home cosy. in warmer months, the film is easy to remove and replace so you can open your windows. try stormguard double glazing film, £7.99, available from amazon.
