Insulation

Postby LadyHolland » Fri Nov 03, 2017 6:03 pm

Hi there, we have just bought a 1964 Dutch built steel motor boat and it is in need of insulation and this is a good time to do it due to the forepeak being taken back to the basics. Does anyone have any ideas? We are looking at foam but this does mean that we may have to dismantle a lot of the boat. We are under qualified/ over spent and due to live on her very soon. Cheers M&S

I’ve been redoing the pilothouse roof with some padded vinyl over 5/8” aluminum faced 4 x 8’ sheets of building foam, but the roof is prerty flat. If I had to do it on steel, I’d probably laminate thinner sheets of building styrofoam on top of one another to conform to the hull, or if the space was really curved, maybe the spray on stuff. Check the R-factors on all the options before you decide. Best of luck.

Here’s a shot of the aluminum faced foam board before I upholstered over it. Using contact cement, one could bend maybe 10 degrees over the length of the 7 ft. panel without wrinkling the padded vinyl. Without the foam backing, probably twice that or more. For ultimate flex, the monkey fur stuff works best and there’s several YouTube videos demonstrating the process under “gluing boat headliner”.

Would rust form behind the panel?

Steel tends to sweat as with most materials having a temperature difference between the inner and outer atmosphere. Depending on the condition of the metal now, I would want a good thick coat of primer and paint before. If it’s already rusty, Ospho is your best friend.
