Lizardskin schoolie

[Peterjk]

Hey everyone,
Were still waiting to take delivery of our 31' Thomas, but I'm thinking ahead to insulation.
Has anyone used Lizardskin on the interior or exterior [roof] of their schoolie.
It seems to be a very good sound deadner and thermal break.
Lots of van conversion types are using it on youtube, but I havent seen any school busses.
Heres a link to their site if you havent heard of it.

Its pricey, but for me at 6'2" im at the interior roof line, so dont want to either raise my floor or lower the scieling by insulating it. So my plan might be to use this stuff, and then sprary the exterior roof, and underneath of the bus, leaving existing insulation in place. Basically use it on the exterior only making a thermal break.

Any comments would be appreciated.


Thanks,


Peter

I called the lizard skin people, and they do have one example on their web site of a schoolie covered with lizardskin. For a 31' bus, they recommended 10 gal spray insulation for the exterior roof, and 11 for under the bus for sound deadening. So in all about 1600$ they do give a 30% discount. So im thinking of spraying the roof exterior then applying a sealer, this will serve as a thermal break, to reduce heat from getting inside the bus. The ill spray the underneath with sound deadening , as well as the interior walls. The bus color will be olive-green so its totally ok to pain over the roof lizard skin according to them. Thats the plan.

Here's that bus video i was talking about.

They won’t/can’t state an R value for their product. I’d say for the money you’d be better off using XPS foam inside and painting the roof bright white.

But if I do that, there wouldn't be any thermal break.
I was actually thinking of just going with the existing stock insulation.
Maybe I can use XP's foam in addition to lizard skin if I go that route.

Existing insulation was designed to make a +/- difference of 20*. In 0*, it'll be 20* inside, insufficient in my book.

I watched the video. Sealing their windows did far more for their thermal efficiency than that spray on “insulation”. If that stuff is 1600 to do the whole bus, consider other ways to reduce thermal changes.

Blocking air infiltration will make the space warmer.

Having a light colored bus with a bright white roof will help keep it cooler by reflecting the heat rather than absorbing it.

I am thinking them ill apply just the thermal insulation to the roof, and go with stiff wall and floor insulation.Im trying to stay as thin as possible since I'm 6'2 and am at the stock ceiling line already.

Has anyone used this before on walls and floor?

If you go the lizard skin route, I have their sprayer that I'd sell for a decent price. Used once and well cleaned.

What is the special thing about the sprayer?


DId you like the resuts of using LizardSkin?

They claim the sprayer works better to apply the product than bed-liner or paint sprayers.
I used the noise and heat reduction products in my engine bay. I can't say I noticed much in the way of sound dampening, but I think it is really more to reduce vibrational noise than sound transmission. So I think on large body panels it would help. Unfortunately I can't say for sure on the heat factor as I didn't have a good before/after comparison. I drove in the spring before spraying, then in summer after. Then sold that bus for a better option. Long story-short: I've got no info to help
