Re: A New Though for Mats and Condensation Barriers

No boat from whatever a shipyard is good at insulation.

I coated the deck under-roof with 1" soft technical aluminium/foam, equivalent to 24cm PE foam

Now doing it onto the hull, and bulkheads, wherever accessible, with a cheap roll of under-floor film, a vapor barrier and acoustic insulation.

Unless in high latitudes, the cold surface is the bulkhead, NOT the hull!!

This is puzzling to me. Traditionally, bulkheads identify the dividing walls between adjacent interior cabin spaces. These interior spaces would likely have similar temperatures. Help me understand you.

@ hudson
I'm sorry, but english is my third language...

How do you define the part of the hull which is out of water? (The Hull being the whole fuselage, or body). Shipboard, maybe?
I appreciate your contribution :-)

Point is, only that portion of hull exposed to cold air create condensation.. as water temperature is usually higher in the cold season.
That portion of hull, just a part of it, upon water line, is called 'opera morta' in Italian, it is only a portion of the hull, and a portion of the shipboard (fiancata, sidewall?)

Yes, I understand much more clearly. It's probably best for all to distinguish this as simply above or below the water line.

I agree with your observation in most cases; however, we do notice condensation within our hull below the waterline when we are in New England for the summer. Also in our mild Florida winters where inland waters can be far cooler than the warmer days, but typically, I'm sure you're right in that the air would be colder than the water in winter.
