G'day guys when I insulated my workshop I used "Wool it's a great product it's natural and you can easily cut it, I used a mask because I have rheumatoid arthritis, Fibromyalgia and a host of other immune suppression so I wanted something that wouldn't harm me. Good luck it's a mine field the ceramic insulation is very good I would have used sizalation that is used under iron roofs to stop condensation and it has adhesive backing. I'm glad you are going for the wool great natural fibre you will be pleased with going that way. Stay safe and well.

Your sister in law seems to be talking about open cell spray foam, closed cell spray foam hardens all the way through whilst open cell is full of tiny bubbles which allows gasses to pass through it. The surface layer of closed cell spray foam will harden within 20 minutes and the whole thing will harden right through in 24 hours, as soon as the surface is hard then there's no change of any gasses coming through it and once the whole thing is hard then no gasses can get out as there are no air bubbles.

Closed cell foam is the obvious way to go for so many reasons.

@@TheOofus The isocyanate [Part A] is typically formed from methylene diphenyl diisocyanate or MDI. MDI is a known allergen and sensitizing toxicant. From the EPA: “Diisocyanates are well known dermal and inhalation sensitizers in the workplace and have been documented to cause asthma, lung damage, and in severe cases, fatal reactions.” From the Alliance for the Polyurethanes Industry: “Many amine-based compounds can induce histamine liberation, which, in turn, can trigger allergic and other physiological effects, including bronchoconstriction or bronchial asthma and rhinitis. Systemic symptoms include headache, nausea, faintness, anxiety, a decrease in blood pressure, tachycardia (rapid heartbeat), itching, erythema (reddening of the skin), urticaria (hives), and facial edema (swelling). Systemic effects (those affecting the body) that are related to the pharmacological action of amines are usually transient. Typically, there are four routes of possible or potential exposure: inhalation, skin contact, eye contact, and ingestion.” Are these the reasons? The stuff is toxic!

Michael Chugg Bla bla bla, it’s only toxic when sprayed. That’s why they use heavy protective gear. When settled, it’s the best insulation money can buy. It doesn’t require a vapor barrier. it’s mold and insect repellent, water proof, it’s sound dampening, have an amazing R-value and so on. And also, it sits firm where sprayed and don’t sag like many of the other options mentioned.

Great choice with the Ceramic Insulation, we used it in our previous bus, and are using it again in the bus we are building now.

You sort of left off an aspect of spray on foam. Yes if you cover it immediately, it will push out your covering. Check out how homes are built. You show a video of it being sprayed on, but in home building, the foam is allowed to dry and then a worker takes a foam knife and very long sanding board, cutting and sanding the foam level with the vertical supports. Just thought you should have mentioned it, regardless that you didn't use it. Have fun.

What about a vapor barrier between your ceiling material and your insulation? I would look into that because permeability of building materials, water vapor is going to be a problem.

Wool provides moisture management and therefor does not require a vapor barrier. We are however considering a vapor barrier for our walls and floors. There's a lot of info on HavelockWool.com about this and specifically about using wool in van conversions.

I used ceramic fiber insulation 30 years ago. Great stuff, heavy, sheds forever, expensive, works like fiberglass. I used it in 3000 degree applications, Do you really need all those properties? Have fun with your project. Remember, you probably won't live like this forever.

Although she seems like a smart decent woman, she isn't providing any hard information. Closed cell spray foam completely cures (stops off gassing) within 24 hours. Since it doesn't absorb moisture, there is no chance of mold growth which fabric insulation can't claim.

Hi Rick, the links she mentioned are in our description. If you follow them you can find scientific studies that back up the claims. This is what is listed on the Home Free site under Spray Polyurethane Foam: Additionally, while it is generally thought that after 24 hours, the chemical reaction in the foam is complete, evidence suggests that chemical emissions continue for much longer, potentially exposing residents to hazardous chemicals.[13] Isocyanates are asthmagens and are a leading cause of work-related asthma.[14] The additives typically included in Part B of the foam mixture include an organotin catalyst with reproductive toxicity concerns and a halogenated flame retardant. Halogenated flame retardants are considered a very high concern to avoid because they can be persistent and toxic. Closed cell spray foam also uses a blowing agent that is a highly potent contributor of global warming. If you follow the footnotes 13 and 14 there is detailed information on the studies and recommended precautions to take.

Good so you found what I told you about but where did you find the 4 foot wide roll? I'm using hy tech product that you paint on its got the micro ceramic in it Then tiger foamed it I could see the concern about the movement going down the road but this stuff is not moving and will be sealed up with plywood and headliner materials. Good ventilation is the key for any vehicle on the road. Thanks for the download for the telavator cabinet great design work. Love the video's.
