Secondary Double Glazing

We get so much condensation on the bathroom windows with it being next to the kitchen that i have decided to fit secondary double glazing, i have tried the film and tape stuff you can get from B&Q for around £5 but to use it we had to remove the hopper stays which meant we couldn't open the hopper if it was a nice day.
So to start i had to remove all the sticky tape from the window frames and replace the stays then sand the wooden frames and varnish them, i bought 30 metres of magnetic tape and some sheets of 2mm clear acrylic, we have 11 windows and a Houdini hatch to cover, first job was to cut the acrylic to size then attach the adhesive magnetic tape to the wooden frame. The tape come's in A polarity and B polarity so that they attract each other, so A polarity go's on the window frame and B polarity  go's on the acrylic, it can go either way round it don't really matter but that's how i did it, to make sure they both matched up i put B polarity on top of A polarity on the window frame then offered up the acrylic so it was a perfect match. Now i am able to remove the acrylic if it's a nice day and have the windows open, all i need to do now is find somewhere to store them when not in use but i think they could go in one of the top box's in summer out of the way.
I tried to take befoe and after pic's but they were way too dark so i left the film on so you can see.
