Silver Radiator Roll

[Hobie]

I have bought silver radiator roll from b&q to insulate my hutch over the top of the bubble wrap but under the hutch cover. It is silver on one side and polystyrene on the other. Does anyone know which way around to put it? Silver side facing in or out? I want it to reflect the heat but am confused. Has anyone used this before? I couldn't find silver bubble wrap but thought this looked good as an insulator

I would think silver side in and polystyrene agains the bubble wrap to reflect the heat back into the cage and the polystyrene to act as an insulator behind that but not 100% certain x

Oh dear I've put it over the bubble wrap. Do you think it would be better under it? I have put it silver side down to reflect the heat back in. Not sure if it's going to work but thought worth a try

Over the bubble wrap is what I meant. So u would have the roof, bubble wrap, polystyrene then silver. I think that's the right way x
