3M2170 W-6 Outdoor Insulation Kit, Clear, 2-Windows

Easy to fit. Makes a difference in winter.

Such a simple, yet effective, solution to draughty windows. Very easy to fit. Had air leaking through large front window causing living room to be cold. Instantly fixed on attaching this. Very impressed and £100s cheaper than buying a new windows

Its not the usual standard from 3M - The clear plastic has manufacturing marks throughout. The double sided tape used for fixing the plastic is definitely sticky, but the big issue i found is peeling the top off once the tape is fixed to the window frame. Tricky. That said, the overall finish is ok. Allow an hr per window.

It is tricky to install but does make a difference once you get it all sorted.

I applied it indoors, although it states "Outdoor use only". Fitting was easier than expected. The double sided tape worked perfectly. I was worried about the initial wrinkly look but when I applied the heater it looked clear like glass. I first tried a hair drier but found that a fan heater on 1 kw worked perfectly and easily. You cannot tell the window is insulated. The cold downdraught from the window has stopped. Fantastic value. Highly recommended.

I have used this type of product for several years with varying degrees of success. Although more expensive, the 3M product has a thicker film which is easier to handle and better double sided tape. Once fixed, it shrinks well and removes even quite substantial areas of wrinkled film. In future I will pay more and get more.

Easy to install after I've seen some tutorials on YouTube as long as u take your time . I applied it nice and smooth used the hair dryer and wrinkles free very happy at the moment when i installed it . But after few days the plastic film detached from the double sided tape ... i think the double side tape it's not strong enough or it might be more suitable for the interior although it's advertised for external use .

did the job
