Hi, I am about to clad the boiler of my Torquay Manor and am looking for advice as to what insulation should or could be used.
I'm having a bit of trouble handling the commercial stuff, and have been told corrugated card would serve just as well. This from a builder of numerous first class locos in 5 and 71/4 gauge, one of which won an award at an ME exhibition some years ago. Can anyone comment on his statement.
Thankyou
Keith

Hi Keith
I use cork matting as sold for 00 gauge track underlay. Hod it in place with masking tape.

For some years I have used Kaowool, which is excellent.
Cork also works quite well, as does balsa wood. The latter is ideal if you are using very thin shoot for the cladding and it is a boiler that has lots of compex curves. The balsa can be a mix of strips and sheet, and sande d down to make a fair curve, so it supports the cladding.
Some years ago a pal and I did some experiments on the effectiveness of insulation.
Generally, not really effective in a meaningful sense. It aint gonna raise the efficiency of the boiler by a measureable amount !
Even so, it does cut the heat on the outside of the wrapper.
The most efficient was TWO thin layers (1/8") of Kaowool, with aluminium foil in between.
That compresses to about 1/8", and is more effective that one 1/4" layer, or any other combinaton we tried.

Andy and Alan,
Thanks for the advice. I've made a start using cork and so far it's looking good. Now I've to find someone local who has the means to roll my brass cleading.

I have been wondering if it was possible to use the stuff that welder's gloves are made from (1- 1.5mm coarse leather)? Or the other thought I had was whether a set of the woven type oven gloves might be useable? Probably best to buy a new set or the smell of roast meat or potatoes might be too much to deal with!!!
Cheers

Kaowool is excellent but as said before on another thread my present loco a Winson Baldwin uses cork matting.
