Im thinking to put a moisture barrier between the box and insulation as well as in between each layer.

Any other ideas?

Sail far and live slow.

Marine Warehouse can get you anything in Panama.

Re: Building a Reefer Box with Aerogel

Hey guys, sorry if this has already been covered but I was wondering if eBay is the cheapest source in the US for buying this stuff?

And which is the best material to use for a fridge box - Cryogel, Cryogel Z, or Spaceloft?

Re: Building a Reefer Box with Aerogel

Based on My knowledge of Aerogel and the Specifications of their different Materials I believe the basic Cryogel ( Not the Z ) would be the best material of them all.

My reasoning - it is the Lightest of all their materials at 8 Lbs/ Cubic Foot.

Also if you look at Cryogels recovery after compression it has the highest load capacity at 250 PSI.

Between these two characteristics - Best Compression Recovery and Lightest Weight - and at the relatively low temperatures we are speaking of - Neither Super Hot or Cold - I think Cryogel is the Call.

One of the reasons that Aerogels are so effective is that they are mostly air. The best Experimental Aerogels - at insulating - are nearly if not lighter than air. The Materials in discussion are what is commercially available (and at a reasonable price ) at this time but don't really meet the full promise of what these types of materials may provide or show promise of in the future. Although the truly exotic stuff is available at exorbitant cost and not practical - or available to the average Joe - at this time.

My Two Cents. Ultimately this is a simple observation on my part and if you could actually get a real product engineer ( Not a Salesman or as they are referred to, a Sales Engineer ) on the phone from Aspen Aerogels then I am sure they would be the best source for your answer.

Their Phone Number is 508.691.1111

Re: Building a Reefer Box with Aerogel

Ask and talk with Mario at Aerogel, he is quite technical and should be able to assist. We use their products for deep water high temp pipelines (pipe in pipe) and they are effectively the market leader in insulation technology. I've been in pipeline design for many years, used a few similar products, but we return to Aerogel. I'm sure you can find a good thermally conductive and thin (compressed) blanket for your fridge.

Re: Building a Reefer Box with Aerogel

I am wondering if this is possible to eliminate the the condensation issue- can you put on the Aerogel and then to a "vac bag" system over it? Maybe use visqueen to size, suck as much air out as possible then seal it shut. Would this negate the insulation properties by removing the air? Just trying to think of a way to negate the condensation issue while being able to use the best possible insulation......

Re: Building a Reefer Box with Aerogel

Condensation can be a problem if the door seals are faulty.
