Loft insulation in car???

[Jeffds1360]

Anyone know what this loft type insulation I have between back seat and boot area? Black Plastic wrapped but falling apart. I've removed and binned it whilst doing a bit work.

Should I replace it (sound deadening?) or what was it for?

Could fill the area with expanding foam??

That sounds like the original stuff and I dont know if its horse hair in the bags but something like that😄 I would replace it with something as these cars are noisy enough as it is!

Cheers Johny, it is just sound deadening then... hmmmm polystyrene chips then maybe?

Filled a crisp bag with the 'wriggly ' ones a canny few year back at work and offered them to a colleague.  He ate a few and said... not much flavour!

A lot of us use stuff called Silent Coat sound/heat deadening on the tunnel and under carpets. Works extremely well and easy to stick on. Have a look on FleaBay.

Im replacing all my 'bags' with 30mm adhesive backed closed cell foam sheet. It works out cheaper but dont know how effective its going to be...

Another vote for Silent Coat . Best prices were from Amazon

Another user of Silent Coat here too. Got mine of fleabay. Prices fluctuate. Have a good look around and be prepared for the loud thump when it arrives or a postie with a hernia. Its heavy stuff. Dodo mat is also very similar, Colin will advise on that.

the orig bags fill the voids between boot and passenger compartment 

helps keep exhaust and diff noise down a bit  any thing to bung up voids make a more solid feel to the car 

the matts wont fill voids but really do stop any panel drumming 

you can find the old bags poked in a number of places  rear 1/4 side panels  and base of A posts   etc

Great stuff lads. Mine had gone rotten and made my arms itch. I'll find something without asbestos in it. Old woolly jumpers perhaps???

Excellent stuff. Very very good in stopping heat from the gearbox tunnel. Unfortunately that means having to drive with the windows closed, which as a GT6 driver I'm not used to.

Used offcuts of rockwool loft insulation in heavy duty black bin liners.

I replaced all the original sound deadening on my Vitesse a few years ago using black rubble sacks and Acoustic Earthwool. Think the original stuffing was Kapok.The bags were cut to the various shapes and heat sealed, cheap heat sealer off eBay. I just pushed them into the cavaties. I used spray glue for inside the rear wings. I think Triumph used this method because of the large caverties, They used the black bitchermen patches on flat panels to help stop them resonating.

Now that is a good idea!
