Improving the insulation value of your home will reduce your heating and cooling bills and increase comfort. While most of your house consists of layers of cladding, framing, plaster and (if you're lucky!) insulation, your windows are just a thin pane of energy-transferring glass, leaving big gaps for heat to enter in summer and leave in winter.

Permanent double glazing can be hideously expensive, and while very effective and recommended for new builds and renovations it's not practical for renters or people on lower incomes.

Duck Window Insulation kits work by sealing and trapping a thin layer of air against the glass, working like double glazing to slow the transfer of heat through your windows, while being cheap to buy, easy to DIY install and removable. Even if you're considering installing permanent double glazing, you can use this Duck window insulation to see how much of a practical difference it will make before outlaying thousands of collars.

Duck Brand window kits have everything you need for installation: the crystal clear film, and Duck double sided window tape. Guarantees a draft-proof seal. Non-splitting shrink film and tape removes cleanly and easily at the end of the season with no residue. Use a standard hair dryer to shrink the film to fit and provide clear view through.


How to Install Duck DIY Window Insulation

  • Watch here for step by step guide for installing this kit
  • *For indoor use only* on painted or varnished wood, aluminium, vinyl 

   * some customers have reported issues with the tape not sticking well to some aluminium window frames. Please ensure you have thoroughly cleaned the frames first with a suitable degreaser such as methylated spirits or pure alcohol and press down firmly over the film and tape with a smooth. hard object after application to ensure good adhesion. A better solution that also addresses the issue of the aluminium frames being very thermally conductive is to make a simple painted or varnished timber frame that fits tightly inside the window reveal and sits against the aluminium frame. (Use rubber weather stripping around the edges for an airtight fit for best results.) Apply the Duck film to the timber frame, even better apply it to each side of the timber frame for triple glazing. Add some offcuts to the front of the frame as handles to make it easy to remove when you want to open the window.
