Shade cloth in the UK is put on the inside in a lot of cases.I've never seen the shade cloths put on the inside before. Any particular reason for this ingenuity Steve?
It is really easy to put up as i found some plastic do-dahs that simply twist into the aluminium glazing bars.These can also be used for bubble wrap.
I know that with the shade cloth external it helps to keep the heat down in the g/h but we rarely get really hot days.
If it causes to much heat build up then i will change it to external.
