Re: Sound Proofing
I'm halfway through this on my Bristol. JMS Online has some good prices on the Soundown products, but still I've spent about $300 so far. I used 1" thick with the barrier, doubled up in key places for 2". (key places = cabin sole and engine compartment doors)
As the engine noise gets quieter, other noises, eg rattles, are becoming more obvious - the campanionway sliding hatch, the hasps on the lazarettes, the swim ladder, the list goes on, they all rattle. I couldn't really hear them before. I will be going around with some self-adhesive neoprene to try and stop them.
I used the pin kit for the cabin sole, as I don't want to drill holes and I don't want the insulation falling down. 1 minute epoxy from the hardware store works well to glue the pins to the substrate.
For other surfaces I'm using 1" screws with 1" OD coach washers.
EDIT : The Soundown and the Barrier 104 look similar. I couldn't easily find an online supplier of the latter, last time I looked.
