Heat insulation

Hi all

I have been thinking of installing some form of heat insulation in the roof and rear side panels of my 90 County Hardtop. The rear sides and roof section are lined with the panels it left the factory with, so I was going to remove these and install the insulation direct to the metal.

This may be controversial but I was considering using solid Kindspan type 25mm solid insulation board and cutting it to size so that it is a nice tight fit between the edges and strengthening crossmembers.

Anyone here tried this approach?

I haven't tried Kingspan... But on the roof I used some adhesive silver faced foam. I got it from Lasalle trim (as they're relatively local it was easy to collect as I was passing) but there might be cheaper options available.
I've found it to be pretty good, and flexible enough to be cut and shaped.

I think it's made the car warmer and stopped any condensation issues, so worth considering IMO. Donald

I used a 10mm thermo liner from deadening.co.uk. It is a closed cell foam with a foil barrier that comes in a roll and you can cut with scissors. That was on top of a sound deadening layer, I used silent coat, but plenty of options there. Easier to install that a rigid board type insulation. Especially on the underside of the roof over the forward cab area. You can wrap it around the curve on the outer sides. Plus it fits under the exisiting roof liner. Not difficult to do and well worth the effort. Not just a thermal barrier but also a sound barrier. My roof is black, and it made a world of difference.
To finish the back off I used mudstuff plastic hard top side panels, but you could easily use the carpeted type if you want to save a few pennies.
