heater insulation

has anybody bothered to put insulation on their heaterbox on the outside like original, and if so what did you use?
Thanks

Hi,

I used this stuff when I rebuilt my heater last year. Appearance wise it's not factory, but it helps keep a lot of heat out of the cabin. Even on 98°f+ days here.

Dynamat 11905 Hoodliner 32" x 54" x 3/4" Thick Self-Adhesive Sound Deadener Amazon.com: Dynamat 11905 Hoodliner 32" x 54" x 3/4" Thick Self-Adhesive Sound Deadener: Automotive

I know the stuff Dynamat, have sold it when i was at repco.
Exceptionally good product and have seen it used in a Vauxhall Victor under the bonnet.
I was hoping to get away from the silvery colour of the foil though.
Thanks for the link mr s dibbers

i didn't mind silvery look but as the original black insulation is there ,albeit not best state. i used the aluminium foil you get that goes behind radiators split down so using half thickness. carpet glue and smoothed on . seems to look much tidier though will replace later as black I think works better there. but this will suffice for a few moths until winter storage again when I will be replacing carpet very likely at same time.

It's made

It's made the car drivable on summer days. That and replacing the dust for foam rubber gaskets on the bulkhead and inside the heater.
