Fire proofing and Sound Deadening

[Tony B]

I recently finished my new floor boards which is actually the cabin sole directly over 2 Crusader 270 engines. There are 8 boards are approx. 2' X 3' each.
Sound deadening is not too much of a concern, however, some sort of fire retardant or fire proofing should be in stalled.
What is recommended for the sound and fire proofing insulation?

I got this info from another forum.

Has anyone here tried this:
" I'd use a layer or two of fiberglass ceiling tiles, the kind used in dropped ceilings 2' X 3' X 1". They meet commercial building & fire codes and have an easy to clean textured layer on one side. You could put a layer of sheet lead between 2 layers for the ultimate in soundproofing."
I have used them with great success on both gas & diesel boats, they are cheap and available at Lowes or HD."

I've been wondering about this. Let us know how it goes if you use ceiling tiles.

Acoustic foam is also available.

Thanks for posting it. How does the fire retardant abilities compare to the Mylar self-adhesive products?

Here is what I did today.

I spent most of the day working on a new settee, so I only did one just to see what I would be up against. it went easy and everything fit snug.
The first pic was with the ceiling tiles in place.
I used really large washers to hold everything in place and secured with Stainless Steel screws. Forgot to take pics of the finished product.
Tomorrow i will finish the rest of them
