Insulating a defender have you done it and was it worth it?

Thanks Andy. I haven't seen 'car builders' before. Very nice website. I was just about to order dynamat extreme and hoodliner but better have a good look at this mob. So much for congratulating myself on making a decision. Cheers

Recently i had the transfer case out to upgrade to an Ashcroft lsd central diff. Took the opportunity to put the stick on head shield from car buiders up in the transmission tunnel, that and wrapping the exhaust has made a huge difference to cabin temps

For pure thermal insulation on the roof, I'd use 'armaflex' sheet.
Armaflex is a brand name, it can go by Supalon, etc.
It's the stuff we use on refrigerant pipes.
It comes in large sheets and various thickness, e.g. 10mm, 13mm, 19mm, etc.
Use contact adhesive to glue it in place.
Obtain from a refrigeration wholesalers like Actrol, Reece HVAC, etc.

Also highly recommend wrapping the exhaust to the back of the t/case.
I did that on my old Deefer quite a few years ago.

Thanks, I'm hearing more options by the day. I've barely driven mine over the past 10 years and developed water leaks. I pulled out my front floor mats and insulation about 5 years ago. The love has since returned and I pulled out my drivers side firewall insulation to replace all the rusty washers.
So my priority is put down some 'stage 1' or dyna mat, and then get all those factory mats down again. I don't remember a huge noise issue back in the day but last drive with everything out I was pushing 100dB.
Cheers Mark
