Fire Block Foam

oscar1

Any one knows which is the type of fire block foam ( my boat has a black color type ) was use to seal between compartments in our Rinker boat,  or anything to use for the same purpose. Thx

@Black_Diamond he's talking about stuff like this, to prevent fire from moving through bulkhead penetrations:

That's a product for home construction, but I don't know what Rinker used.

They make in a caulk tube as well. I use it a lot

 So the regular household (home depot) type can be use in boat too?

I wasnt aware that Rinker used Fireblock foam.  I always thought that it was just sound proofing.

Sure if you just want to seal up penetrations on the fire wall

skuter99

how do you keep it in the place you want it when spraying the foam, just piece of carboard on one side or something?

LaRea

Fire block is used to seal around a pipe or conduit that goes through a bulkhead or floor.  If you have a 1" hole with a 3/4" pipe, you fill the gap around the pipe.  It's usually a small gap.

I thought it was only used for vertical pipes.  I didn't think it was used in small boats like ours.

This is the foam I have between the engine room and the rest of the boat bulkheads. Thx

Maybe a previous owner added it.  I don't have that, and didn't have it in my 342.

I bought my boat brand new from Rinker (only one owner myself)

Not sure what the ABYC standards are, but when I was a facilities manager building codes specified fireblock foam/caulk had to be red/orange in color so the fire inspector knew at a glance that it was fire rated.

I wonder if that's just regular foam? You could cut a chunk off and see if it burns.

I want to say I have it in my ‘08 330 but it’s painted white. I tried to go through pics but didn’t have a shot of the areas.

Found some! This is behind the cockpit refrigerator.

davidbrooks

I dont have that at all.

My boat also has that same black foam.

Well I going to use what LaRea said Fireblock to seal the section where the mistery foam is gone. Thx to everyone for their inputs.

I have none of that foam sealing openings. There are MASSIVE openings on my 342 on the sides of the firewall per se.

I have the white foam along the very bottom of the fwd firewall where the mid-cabin bilge hose runs thru.

davidbrooks

The whole concept of a firewall on a 342 seems a bit pointless to me.  Like @Black_Diamond said my 342 has huge openings that run all the way through.  Both port and starboard have openings that are at least 12x16 from the engine comparment forward. So a fire in the engine room has a nice double chimney.  The fuel lines seem like a nice fuse to a couple hundred gallons of fuel.  The fuel tanks are then completely open to the cabin.  Sooo if there is a fire i am getting wet and making a call to insurance.

I’m moving into a new office that was renovated at the hangar today. Saw these sitting on the windowsill.

I'm thinking of installing removable plates to block off those openings.  My goal was to reduce engine noise in the cockpit while underway, but I hadn't considered the safety benefits.
