Rainscreen: What is it?

A Rainscreen is a perfect way to install insulation on the outside of the shipping container building. This video describes what a rainscreen is. It also points out the 3 reasons they work well on shipping containers.
Here's the link to an article that shows how the siding is installed to the outside walls of a shipping container: liveinacontainer.com/how-to-a...

... I'm looking forward to your ideas on attaching rain barriers/ insulation on the outside. I dont like (but not opposed to) drilling through the container.

[@liveinacontainer6602]

Yes, drilling through the container is counter-productive. But, with minimum penetrations, neoprene washers and additional sealants at all penetrations before concealing the penetrations with finished walls/floors/ceiling material, the threat of water entering the container can be mitigated.

Hi from Texas. I've got 100 acres fully off grid with LiPo battery bank/ inverters. I went with spray foam inside (GREAT vapor barrier) and 3.5" thick insulation. I also used spray foam and rigid foam boards cut to 4.5' wide to adhere them to the valleys in the corrugation on inside between spray foam and 3.5" baton insulation. This makes the valleys fully insulated too. I built out the interior with a bathroom, kitchen, and bedroom. I used 1/2' drywall in the middle and outdoor plywood in the bedroom and bathroom. I used 2x4 to frame everything and spray foam under/around all 2x4s. The spray foam backing under the 2x4s over the ceiling make it MUCH more stable when im walking up on the roof.

Howdy fellow Texan! Thank you for letting me know how and what you did with your build. I really appreciate it.

Thanks for very a helpful information!

You are so welcome! Stay tuned for other videos about different rain screens to come.

Thank you! Great information. Subscribed!

Awesome, thank you!

Verybwell done and explained. This would work well in Ontario Canada and give more space inside. Theanks

Thank you for your feedback.

Hi, great info thanks. I watched your best insulation for shipping container homes video where you talked about closed cell spray foam on the outside. I'm wondering if you use HIGH DENSITY closed cell foam, which is waterproof, would you need the added expense of siding? I'm planning a container home & trying to keep costs as low as possible. Thanks for your help, Christine

[@liveinacontainer6602]

The insulation should be covered against excessive UV exposure. Check with the product manufacturer's recommendations. But, generally, spray foam will deteriorate if left exposed too long to the sunlight (prolonged UV exposure). Carlisle is one of many companies that provide insulation products. Here is a white sheet from them...www.carlislesfi.com/wp-content/uploads/LTR-CSFI-UV-Closed-Cell-Foam.pdf

Hi Larry. GREAT VIDEOS!!!, PLEASE keep them coming. Can you recomend how to get a copy of the current IBC codes for container homes. I have been srarching the internet, but to no avail. Any help would be greatly apprieciated. Thanks in advance. Sincerely, Jim G.

[@liveinacontainer6602]

Thank you for the complement. Check out the video description of the following link to get a link to the IBC code that has the part about shipping containers: kzbin.info/www/bejne/rpO1iXquZs2SrZo

Warm air mixing with the cool air on metal can cause insulation mold, thats why insulate the exterior!

[@liveinacontainer6602]

Yes, as mentioned in the video, having insulation on the outside pushes the dew point towards the outside face of the building. The condensation will occur near the dew point. Condensation can cause mold. There is also a better chance for the mold to have a hard time forming on the outside if the outside air is ventilating the dew point surfaces. Thank you for your comment.

Larry, what can be used as a barrier between the container floor and the concrete foundation? I want to protect the metal long term from water contact etc. What to do? Any thoughts?

[@liveinacontainer6602]

Here are a couple of options. There are more, but maybe one of these will work for you... 1) You can place the container upon reinforced concrete piers. That would raise the underside of the container above the wet ground. Then, spray closed cell foam insulation on the underside of the container to act as a thermal insulation and vapor barrier. 2) Another way is to place the container upon a reinforced concrete stem wall. That would also raise the underside of the container above the wet ground. Then, insulate the underside. Here is a link to a video about those types of foundations: kzbin.info/www/bejne/hpq1eIeGgpKMaNk Here is a link to a blog post about those types of foundations: liveinacontainer.com/what-is-under-a-shipping-container-home/ Hope this helps.

[@benjaminAgagne]

Do you think Adobe or cob could be plastered over the rainscreen? It would look like a classic Adobe.

[@liveinacontainer6602]

Maybe the stucco rainscreen would be sorta like an Adobe appearance. See www.stucoflex.com/rainscreen_drainage_mats.html

[@benjaminAgagne]

@@liveinacontainer6602 Very cool! I’d like to save and use some of the soil around my land to make adobe plaster. It would be applied the same way as stucco. The interior will be Tadelakt with polished earthen floors. Spanish colonial kind of twist.
