Tips for installing
Installing DIY window insulation film is relatively easy – you only need a pair of scissors and a hair dryer.
Make sure your window frames are dry and the paint is in good condition to avoid condensation forming inside the air gap.
For wooden windows, applying a bead of sealant like silicone along the glass edge will further reduce the risk of moisture creeping into the air gap.
Make sure your window pane is clean and streak free before putting the insulation up.
