Insulating a Roof Gap

(1/6) > >>

awemawson:
My workshop is a converted barn with corrugated fibre cement sheeting roof. It's been sprayed with expanding foam and when they did it they assured me that they'd sealed the apex where there is a 'top hat' shape.

Well they obviously didn't - I recently had an enormous bonfire ( 1/2 mile of Leydandii hedge top  :bugeye:) - and there is a line of 'fall out' ash down the length of the workshop. So if the ash blew in then my heat MUST be able to go out  :bang:

No chance of getting them back, as access is now very difficult with all the machines in place, and I don't want them covered in foam anyway !

SO - my thought was some form of insulating sausage that I can poke up there with a long stick - if there was such a thing as a 6" diameter cylindrical shape I reckon it would stay in place by friction.


 :scratch: :scratch: :scratch: BUT YOU MAY HAVE OTHER SUGGESTIONS PERHAPS  :scratch: :scratch: :scratch:

vtsteam:
What about pipe insulation? Or the colorful equivalent "pool noodles" ?

awemawson:
That was my first thought Steve but I've not found any in the UK of a sufficient diameter - above 35 mm bore it all seems to go into foil wrapped fibreglass which won't have the 'friction staying' power I think :bang:

bertie_bassett:
How about 3or more of the pool noodles duct taped together?? Wont be the best looking, but might do the job??

They have it up to 4 inches on the drop down list to bulk it up one inside the other
