Im refering to the concertina (flexi!) ducts from heat exchanger to body. Anyone re-packed these and what with. The stuff thats currently in there is getting too hot and breaking down! Im hoping someone has a cheap simple solution like fibreglass insulation (rockwool) or similar. Ideas Ta
When i done mine a while back ,i used the stuff you may chose to insulate the attic floor with ,and also put silver foil sheet(s) between the webbing and body of concertina flexi thingy.
