tcm? thinsulate noise stuff

[andyball]

Do I remember right that you added loads of this to D2?

I've used 'some' ( lack of ££'s) on ours & thought it rather good. If you used it - What sort of stuff had the builders fitted? & was it a huge improvement.... or another copper-type experiment that didn't?

ta in advance

the noise insulation in the boat was a bit rubbish. I added to it, used Halyard, 35ishmm with interlayer of plastic, self adhesive with push-though supports or screw on ceiling, just self-adhesive on vertical walls. peope lrate the thinsulate , tho i reckon the thicjness must be better, and an interlayer (as with halyard, not thinsulate) must kill noise better than none.

The most massive difference thos is to the actual engine hatch. yerknow the diference between closed door and just-open door - massive. And just a layer of 32m is ok, but IO remeber from some course at uni ior somewhere that sound reduction continues all the way to 6inches of insulation. I at last have about 4-5inches on engine hatch, tons quieter.

Sepretly, i have oodles (nearly 200) pieces of self-adhesive black foam, going cheap (though quietly, haha). I was going to insulate the flat but decided against it due to utter laziness and turning up the heating . This isn't as good as the halyard stuff but not at all bad and dog cheap. £1 a sheet 25mm thick and 1m x 1metre plus probly loads of p+p. Plonk layer after layer on, no cracks and it will make a difference. In fact i suppose this cheap you could bosh it on and see if more expensive stuff will be wortwhile, sort of.

Supportting the stuff overhead is a big issue - i fouind some special fixings tho screw would do, ort battens and screws. The self adhesive won't hiold for long. But self-adhesibe loads better than sepret adhesive pratting about and taking ages.

Not tried thinsulate. Apparently quite good but I am not so sure without any interlayer as above. Also ends up a bit of a mess in wooly black i believe so needs some covering for smart engine room look, or best behind walls etc. My cheap stuff is also black and foamy instead of wooly AND it's cheap, see, so that's sort of ok, in a cheap sort of way.

thanks for that -my memory playing tricks re you using thinsulate.

from my limited use, it does a decent job despite lack of a barrier layer... shame about the price. wooly black tends to tear v.easily & silver face costs even more. ( ok, no more than quality barrier type )

Totaly agree with TCM about self adhesive being rubish on horizontal surface, i got a hole saw and cut out some disc's of plastic sheet (although i guess thinish ply would do) and screwed that through it

Re: tcm? thinsulate noise stuff

Thinsulate is actually the best for many reasons but it needs more than just a look around and throw some thinsulate at it.

You need to carefully work out how the sound is moving and where it is escaping from. Sound is vibration, so you need to find out what materials in the area that you are trying to surpress.

You also need to work out where sound could be escaping from ie a void or vibration and where it is ending up.

The addition of sound deadening pads and using the two types and two thicknesses of thinsulate in the right areas will help.

I have fitted out a few boats this way and seen some really good noise reductions so much so that conversations can be held at high speed and that the driver can be involved in the conversation going on behind him.

Let me know if I can help.

Re: tcm? thinsulate noise stuff

ah yes - *you* have commercial interest hence thinsulate is the best and the rest is no good, scientifically, somehow. Let's not go there.

Different insulation wuill work for different types of noise. The halyard stuff works, and i imagine so does the thinsulat

Re: tcm? thinsulate noise stuff

We used the Halyard stuff too replacing the finger type foam that our Princess Came with. a huge difference in engine room and around 10kva generator.

Re: tcm? thinsulate noise stuff

Matt I understand that your knowledge of the product is slim and probably of accoustics thats why you slapped it on and hoped for the best.

I am saying it is the best for a number of reasons.

1 its weight advantage over other products, weighs next to nothing in comparison
2 its flexibility and ability to fit into tight spaces or round corners or unusual shapes
3 the ease of which it can be fitted ie spray adhesive stick it on and walk away
4 cost
5 it keeps out the heat in the summer and keeps in the heat during the winter

So i still say its the best based on fact, not on the fact that I sell it cos if I thought it was worth it I would sell the Halyard instead.
