Mum and I started insulating fresh one frosty morning but the mood wasn’t great. But we got it all done in record time and the bus is going to be a lot warmer for it, but both of our patience has been greatly reduced!!
First step…Therma Wrap
Then proper 1 inch thick motorhome insulation. This is the correct fire approved stuff.
Then add a moisture barrier
And fit your nice new door cards
