Insulation for steel

[AlexHall]

Does anybody have any suggestions other than Spray on Urethane? I have read about Ensolite and Neoprene, iare these available in the UK?
Has any body used anything else, like Rockwool or the like. Has any body a steel boat without insulation? But basically built a wooden boat inside a steel one?

Some people use cork as beeing environment friendly.I can give you more detail on that if you want.

Hi Thanks for suggesting cork. to be honest I have not seriously considered cork due to the inherent nature of the stuff to absorb water/moisture.
Talk to me, I like the idea, but does it work?
eagerly awaiting news.

I thought cork was waterproof - it does float after all. Should work OK on steel and give noise and heat insulation, but I suspect you woul need it to be thicker than the average floor tile.

I'd rather be sailing...

I have what could almost be described as a wood boat inside a steel boat, except the wood doesn't run right into the bilges. Separating them is 2-3 inches of polyurethane sheet foam insulation. It is extremely effective, allowing the yacht to be used comfortably all year round in England, and proving very cool in the tropics.

The foam has the advantage that it is easily removed for maintenance, and though it tends to crack up is very cheap to replace. It's not the most basic grade but a rather denser version sold for use in damp areas in housing, and resists absorbing water.

Seems to work...

met a scandinavian couple in a steel boat who had come south to inverness for the winter (yes, really, from spitzbergen!) theirs was lined with neoprene and they were a lot warmer than us. neoprene is available from various sources (it's used for wetsuits, car body seals etc. etc.)

I have no personal experience in using cork in boats, but I do know that it has been used a lot and was also used extensively in the refridgerating industry before polystirene etc.
Cork is obviously environmently friendly and doesn't leak any nasty gasses unlike some foams(I think).
For more information (unfortunatly in French)log on www.au-liegeur.com and look in techniques then isolation. You will find all the different sizes available.
PS, I am French so don't hesitate to contact me if you need help.
yours.....Maurice.
