Re: Insulating Your Interior

I had mine done with eurathane/ isocyanate spray before last winter. Everywhere from the sole upwards. I used a firm in preference to hiring the equipment and doing it myself.

Same as in previous post

One size fits all, no gaps, you can vary thickness to suit location, prevents warm damp air access to the hull so no condensation and only 2 hours to apply to a 50'hull.
Ok, it was another day to trim back and clean up, plus of course, it was an empty vessel, no obstructions.

Cost was £730. If your tied to the dock and heating with gas/electric, living in a cold climate, you might save that much in 2 years plus you wont be dripping wet and mouldy.

Sticking sheets to hull sides is ok in a straight flat place but you wont have the same results on a curve surface.

Re: Insulating Your Interior

Our boat is steel therefore some kind of insulation is essential. Whilst still in the constructions stage the hull was fully foamed apart from the lower sections which were left clear for bilges. The deck head was insulated with insulating 'bubble wrap style of stuff. Jimmy Cornell has an article about insulating his Alubat Ovni using foam and he cruised to very high latitudes north and south.

Yes.. the drawbacks compared to sprayed foam is the price and more work, but it has much better damp and fire resistance. Most respected boat yards use it as a standard (never sprayed foam). There's also possibility to use some cheaper insulation on top of it.

We did our last boat with the foil bubble wrap foil insolation. It was great, both in the heat (Charleston SC) and in the cold, down to18f. We also found the boat much quieter. on the present boat we use it to cover all the ports and hatches. I hoped that the foil would improve the boat radar reflection also...

What is this bubble wrap insulation everyone talks about? can someone send me a link of what you mean? I don't think I can afford Armaflex. How much is a roll? When I google it all I got was sleaving for pipes.

Re: Insulating Your Interior

Bubble Wrap ➥ Bubble Wrap, Bubble Wrap Toronto in Stock - ULINE.ca

Isn’t a very good insulation, nor is it very durable.

1" thick Armaflex sheet & roll list for < $4.40 square foot.

Re: Insulating Your Interior

Yeah I don't think I would ever use that stuff, it wreaks of a "cheap" fix.

What about this?

Re: Insulating Your Interior

Imagine was insulated when built. She has 3/4 in of styrofoam, and 3/4 in of closed cell foam. During the years of small repairs, and add ons. I have never found any moisture marks. The boat is completely insulated from roof to water line. She heats up easily, and stays cool in the tropics.......i2f

All applications, with an R-Value claim, must have an enclosed air space (a cavity without free air flow) or face an open air space.
