Conversion problems

We spent a good part of the day fitting this stuff. It entailed (a long overdue) cleaning of the windows, then perching of the sill, trying to get the film straight and trimming off the excess; but now it's done! We did this last year and it immediately made a difference, and paid for itself in no time.

Luckily we have imperial measurement windows..if you have metric, the film hardly covers anything at all..... ;)
