Deckhead insulation

Deckhead insulationI know the picture does not show much, but it is pretty significant.

What you are looking at is a section of the recently completed insulation of the deckhead down below in the aft accommodation space.

With the heating on, the difference in temperature before and after the insulation, relative to the galley above, is very noticeable.

I'll also see about putting insulation sheeting over the exposed steel beams.

Every bit helps, as come summer it should also help keep things cool down below.


  1. hi tim, love the blog and have been reading for a long time now. What is the spray foam that you're putting between the celotex boards called? We've been looking at various insuation solutions for our dutch barge ( ) and yours looks great. I think the one way membrane idea is a good one too, the general consensus from discussions with our friends on another dutch barge ( ) is that you don't want to seal the moisture in with the insulation. Obviously this is even more of an issue if you're using something like rockwool which will go nasty and rotten when damp, but even with celotex i guess it's worth keeping nice and dry.

  2. Hi Steve

    Thanks for the comment.

    The spray foam is from Spray Insulation Ltd -

    It's a closed cell foam, so absorbs no moisture.

    I will need to take the insulation from the deckhead back out at some point, so did not spray the whole place as I did the sides.

    My thinking in insulating the sides like I did was to prevent water getting in in the first place.

    Have a chat with Chantel (01275 778 195), she has been very helpful.

    Good luck & let me know how you get on.
