Living in a rented flat, the windows are single glazed sash windows which are rotten, haven't seen a lick of paint in many, many years. The landlord will not fix them (or the leaking roof, but that's another story.)
Last year, it got so cold that we had about three cm of ice on the inside of the glass, where condensation froze and built up. So I bought that film from B and Q that you tape around the window and shrink with a hairdryer, which made a huge difference, but it won't stay up. It lasts about a week, and then peels off the tape. I have tried sticking it down on the outside with masking tape, didn't work, and then builders tape, but that just peels off too.
Any advice on how I could get the damn stuff to stay up? I know you can buy more sophisticated secondary glazing, but if I could afford that, we wouldn't be living here in the first place, and anyway, we would need his permission to put it up. Quite frankly, I don't think the wooden frames would cope with screws being put in. The windows would probably collapse out into the street!
