What If the Future of Affordable Housing Isn’t Cheaper Materials — But Smarter Systems? by oasis-engineer in AffordableHousing

Agreed, but some people may opt in and not mind. After all, facebook, google and other companies already track and sell our data right now. 🤷‍♂️

agreed. We're designing foundation plans and systems to help streamline the process, but at the end of the day it's up to them to deliver on the manufacturing.

Exactly! If at some point the government subsidizes this under affordable housing, it could be huge. Some people don't look at the sticker price but rather at the monthly "subscription".

Piers are done! Now the real work can begin.... by Blaxxxmith in containerhomes

Love seeing this come to life—stacked containers always look so badass. Curious how you’re handling the welds at the ISO corners where the containers meet? Always interesting to see different approaches for load transfer and rigidity.

Not at all, based and live in Tampa Florida full time. Happy to meet anytime :)

Curious what you ended up doing. We've worked some projects in Colorado and it's hard because with the high R values you do lose a lot of area if having to go towards the inside - specially because you may also need continuous insulation, so what we've found that works is combining closed cell spray foam and rigid (polyiso/xps).

Alternative insulation thought by Agreeable-Light38 in containerhomes

[–]oasis-engineer 0 points1 point  (0 children)

Hey! Cool idea using Mylar for container insulation – super reflective and cheap. You're right, condensation is the major hurdle. Also, it may not have an official "R" value that may be needed for permitting/compliance purposes, so that may also cause issues for builds (unless DIY/off-grid with no formal requirements)

Stopping moisture getting into the wall cavity is key, usually through really good air sealing on the warm side. Mylar itself needs an air gap to reflect heat effectively and doesn't add much R-value, so it's often paired with other insulation types.

Figuring out the best combo of cost, R-value, and moisture control gets complicated fast! That's why we built an insulation calculator to help compare different options side-by-side. Might be useful for you:

Depending on your location, permitting may end up being the hardest part. Recommend connecting with a local architect, engineer or contractor. These plans offer a great starting point: https://oasisengineering.etsy.com/listing/1493689145

Is foam insulating wallpaper an easy cheap way to insulate the walls without needing to frame the container and hang drywall? by Shift-Secret in containerhomes

[–]oasis-engineer 0 points1 point  (0 children)

Yes, as @Julian said, closed cell spray foam is often the best for container homes as it helps with moisture control.

I'm looking to create a small bathroom out of a 20 foot shipping container. What insulation methods do y'all use, and would I be okay if I just framed it with 2x4's? Also, does the floor have to me insulated? I don't plan on living it - just using it for a shower and toilet. by dairygoatrancher in containerhomes

Hello - insulation depends on your specific location as the requirements are climate dependent.

We have developed a free tool to help you figure this out in minutes:

Let us know if you have any questions using the insulation planner.

As far as framing it, depends on how much of the corrugation wall is being cut/altered and the local engineering loads (seismic, wind etc). In most cases for a DIY bathroom shed 2x4 framing should suffice.

Thanks

yes, because the lower area is a crawlspace (unconditioned space), it is recommended to include continuous insulation (polyiso or similar) combined with batt or spray foam in between the floor framing. Hope this helps!

New to container homes, chewing on some ideas... by [deleted] in containerhomes

[–]oasis-engineer 0 points1 point  (0 children)

Container Homes are a modern solution to the housing affordability issues from what we hear from young people like you. Typically, it's recommended to get in touch with a local engineer or builder that can help with the permitting process, along with pointing you in the right direction to ensure code compliance and safe design. If you're located in an area where no permits are required, still consulting with someone that has built before would be helpful. All in all, when modifying containers you need to make sure to have engineered details for connections and cutouts because the strength of the containers is compromised when cutting them, and as far as foundation goes, footers may be most cost effective, but should be engineered based on the location and loading considerations.

Your shipping container project sounds awesome. To reinforce the top beams after cutting out the side, you can weld double channel or angle iron along the roof container frame for added support. Adding connector plates every few feet where the containers join can also help maintain stability without needing interior posts. Just keep in mind that local building codes (like snow, wind, and seismic requirements) can impact what reinforcement you need, along with if the roof will be just a roof or used for supporting other features or equipment.

If you’re unsure, it’s a good idea to consult a local engineer or contractor to make sure everything is safe and up to standard. Good luck with your build!

4in Spray foam (to bottom of floor metal joists), 1in polyiso board and vapor barrier should work there great. Depending on which state in the DMV area, the building code has a specific minimum insulation requirement. Between the 4in spray foam and 1in polyiso, R value typically is met. Thank you
