You’d be most welcome Howard!
The huts are designed to breathe, the air gap between the inner (horizontal) tins and purlins and the outer (vertical) tins) usually being vented by ‘witches hats’. I know of at least 2 Museums (actually not aviation ones) where they had to remove the insulation because of air circ and corrosion issues. As I say, if you have galve tins then no worries but if not, use caution.
No issues with BR at all – they were good as gold.

Newark only managed to secure a set of hoops for its Engine Hall the cladding was completely beyond use.
To secure Planning Permission they had to agree to plastic coated cladding to match the exiting buildings and it was completed with only a single set of sheets – seemingly hence the condensation issues.
As the structural calculations indicated that the building would fall down, one of the trustees had to identify exiting sites that used Nissen Huts so the Building Regs people could go out on site and see existing units standing safely! :rolleyes:
In view of your excellent progress this weekend I couldn’t resist getting a Nissen Building item added to the NAM website as Object of the Week – 24.04.11!
Good luck with the LINK!! 😉
