Best Insulation For Bus

I ve seen these types of insulations used in so many bus and van applications but one of the most forgotten aspects of this installation is the air gap.

Best insulation for bus.

Sheep s wool is a sustainable product that insulates well naturally manages moisture and condensation and even helps purify the air in your van. Reflective surface insulation essentially plastic bubble wrap with an aluminum polyester coating can be used to block 90 of radiant heat. So i m trying to think of how to best insulate them. My first thought was spray foam one step yet my understanding is that it can be acidic to the metal breaks down.

You say that the celotex panel has the best or one of the best lambda value in any insulation. The higher the r value the less heat will transfer and the better your school bus conversion insulation will be. Spray foam is the go to insulation for school bus conversions. Just letting yous know.

The best skoolie insulation 1 spray foam insulation. 2 polyisocyanurate foam board. In our opinion the best all around material for van insulation is sheep s wool insulation. The insulation will have a reflective side facing towards the interior of the bus.

Fiberglass insulation is created by fusing natural sand and recycled glass together at high heat. Spray foam was the best r value for the space but would have cost about 1000 eek. There are other options as well i ve seen people use denim or fiberglass insulation for instance but the best bang for your buck is going to be the first two options. For either option you ll want to attach wooden furring strips to the bus first then insulate out flush with the furring strips.

Fibers are created by molting hot glass through miniscule hole creating a thin fiber think cotton candy. I will then cover the insulation with something like a lexan flexible panel material. Before choosing which foam you want you ll need to screw in a thin piece of wood on the metal supports of your bus ceiling and on the walls. Foam board would be an affordable option with very good r value as well however when on fire it creates toxic gas that is lethal.

But after some research i read that celotex is in pir polyisocyanurate which provides one of the better insulation its true but only in warm temperature. With that said you have limited space in the walls. You can either use fiberglass or 1 5 2 pink insulation board which has an r value of 6 9 depending on the thickness you can use stuff in there. But we d recommend using closed cell spray foam.

For our bus we used a thermal break a thin piece of insulation foam between our ceiling wall and pieces of wood.
