sulzerman Posted February 8, 2019 Report Share Posted February 8, 2019 Hi all Got all the carpets out in my 2500. I was wondering if is worth putting sound deadening material on the floor, nothing too thick as the carpets won't fit very well. Any recommendations? thanks in advance Link to comment Share on other sites More sharing options...
Paul H Posted February 8, 2019 Report Share Posted February 8, 2019 I used Silent Coat on my Vitesse . Much cheaper than Dynamat Paul Link to comment Share on other sites More sharing options...
dougbgt6 Posted February 8, 2019 Report Share Posted February 8, 2019 Ha! I also used Silent Coat on my gearbox tunnel, bulk head and footwell. Not very thick, less than 1/4", very heavy, but sound and heat reduced. Big difference on a GT6 maybe less so on a salon. Doug Link to comment Share on other sites More sharing options...
poppyman Posted February 8, 2019 Report Share Posted February 8, 2019 My 2500S has got the standard felt type and does a good job, nice and quiet. Maybe because it's an auto though? Tony. Link to comment Share on other sites More sharing options...
Adrian Posted February 8, 2019 Report Share Posted February 8, 2019 Silent coat and a thin layer of dodo matting Link to comment Share on other sites More sharing options...
Mad4classics Posted February 9, 2019 Report Share Posted February 9, 2019 I always use standard sound proofing felt (the stuff that's black on one side), I like being able to remove all the floor trim - and it works well enough. David Link to comment Share on other sites More sharing options...

David Same here. Bought three huge rolls of it at Stoneleigh back in the 1990s for £15 and have kept using it ever since (including on the roof of my estate!) . If you require anything especially waterproof for the floor (I find the felt very good for soundproofing and while my cars are all dry inside I'm not 100% sure just how waterproof the felt is when placed on floors) go to your local scrappie and get modern-day soundproofing from under the carpets of any scrapped modern; they usually throw it away so will sell it for pennies and it's completely waterproof.

cggs Posted April 15, 2019 Report Share Posted April 15, 2019 Did the Spitfire 1500 originally have any sound deadening material under the carpet over the gearbox tunnel? It's been so long since I threw all that stuff away that I cannot remember. Trying to put it all back together now... Link to comment Share on other sites More sharing options...
dougbgt6 Posted April 15, 2019 Report Share Posted April 15, 2019 The sound deadening on the GT6/Spitfire is two plastic bags of loft insulation (?) stapled to the underside of the tunnel. Insulation on top of the tunnel with carpet on top will make the H piece difficult to refit, although I've seen it done. I used Silent Coat on the inside of the tunnel.

cggs Posted April 15, 2019 Report Share Posted April 15, 2019 Ok Doug. Thanks for that. I have all the plastic bag stuff on the inside so will leave the topsides for just the carpet although I may experiment with some strategically placed bits of silentcoat or underly. This interior refitting business is taking longer than I expected and the moulded carpet set is quite unwieldy especially for those bits on the inner sills. Maybe a bit of self moulding with a heat gun will help Link to comment Share on other sites More sharing options...
dougbgt6 Posted April 15, 2019 Report Share Posted April 15, 2019 cggs, My new carpet is loose, trying to get it over the top of the tunnel, but under the air intake hose is a pain! And the inner sills! Oh dear. Doug Link to comment Share on other sites More sharing options...
Mjit Posted April 16, 2019 Report Share Posted April 16, 2019 The big saloons should have quite a lot of sound deadening already fitted from the factory and (I think from the fun time I had stripping out and cleaning my car after a soil pipe in the ceiling of my underground car park broke and filled it with 'water') applied before the shell was painted. Of course if floorpans have been replaced there's a good chance the sound deadening won't have been. Link to comment Share on other sites More sharing options...

Doug This morning I have found that the trick with the stiff inner sill carpet is to play a heat gun over the back side where it is plasticised - it softens nicely and you can induce (mould ) a permanent bend in it, checking the fit as you go. Working along the length for each bend at a time takes a lot of patience but eventually you have something that fits ok. Link to comment Share on other sites More sharing options...

Don't have that problem with loose carpets, it's soft enough, you just need loads of glue. My problem was the side piece was too short along the top of the sill, I had to cut the curve back on the door frame by about an inch. Poorly made. Got the tunnel carpet in by poking it with my new walking stick. Doug Link to comment Share on other sites More sharing options...
