When companies realised that a new market was emerging a quick fix was found and marketed in the Ceramic coating markets to insulate shipping container homes in reality it was fake. In fact the information they used to justify the Ceramic coatings being used couldn’t be replicated and on top of that you could pretty much get the same result using white paint which is a lot cheaper and easier to find. In reality the best method is SPF insulation (Spray Polyurethane Foam) which is a sticky mixture that fills the voids easily creating a solid wall of foam. I would recommend using this internally with stud partition that you panel over once insulated. Another issue people are overlooking is condensation which causes rust although its not as bad as people often make out due to the design of the ISBU which stands for “Intermodal Steel Building Unit.” It doesn’t rust easily its designed for some of the harshest environments on the planet and has not only got to deal with what the weather throws at it but also being thrown around. Its a solid piece of equipment and if treated properly is going to probably out last most people who convert over to the new modular way of living.
Part of the shipping container housing we are looking to do is to encourage others to get involved and DIY (do it yourself!) which is why this project has come up which is basically we supply “SECONDHAND” containers at P60,000 each now these have been used and will be battered in some way no doubt but you have to remember your cladding over the exterior/interior and on top of that they were designed for ship travelling in some of the worst conditions on the planet. Doesn’t mean they are going to be battered to death but it does mean that your buying a pretty indestructible module if you take care of it. Rust issues will be minimalized due to the type of steel involved and like most things its all about preparation rather than finish.
So if your looking for a 20ft container they are P60,000+ delivery we also provide 40ft but due to the road conditions within Cebu I would recommend buying 2 20ft and welding them together as getting a truck with HIAB (crane) is possible or even using a forklift or backhoe to unload and move to final destination where as using 40ft containers the issues become more complex.

Its probably one of the biggest issues facing container homes as well as the reason many people get put off from building a shipping container home. In reality though there are several options open to people and they don’t all involve specialist equipment.
The best insulation comes from a foam spray currently that can be added externally or internally. Generally I would advise externally as it saves wasting space on the inside of the structure. At the same time the foam spray doesn’t leave spaces for vapour build up which could cause rust or rot long term.
There are DIY kits as shown in the one I added from Amazon personally I advise getting a company in or looking at hiring the industrial equipment especially if doing the entire container also remember to get safety gear as this stuff is extremely sticky and another good reason to get a professional in is insurance.
The next method is using things like glass fibre or injected insulation in between cavities internally or externally. First issue is that it doesn’t seal 100% and if vermin find their way in they can nest inside the walls. It also doesn’t carry the same insulation properties as the foam with a much lower rating currently although like most things in the industry everyone is pushing for better quality and standards so that could change. Also looking at alternative methods there are many other things that can be used on the same principles but I advise a bit of time and research on any insulation methods as every salesman doesn’t give you the negatives just the sales pitch. For me I would go with the batten method with many projects purely down to low cost and also ease of installation.
Specialised insulation or heat reflective paints are still in the early days but do work to some degree can’t really rate them myself as I have yet to find some here in the Philippines but do know the industry says their great while other people are a bit more skeptical so would need some feedback on these types of methods as simply it needs “proof in the pudding” rather than industry fed information
The other method which is my favorite but not always easily available is natural cooling which can be as simple as placing the shipping container home in a shaded area, building a trellis on the side that gains the most sun and growing plants that will cover the trellis. Or raising the building off the ground to allow natural heating and cooling due to using the elements to assist. During the day air travels under the home at the same time the sun heats the exposed ground area which at night naturally can heat the home. Adding into the mix air ducts to naturally force cool air through the home with no running costs or adding a secondary angled roof to use as shade as well as rainwater harvesting are all alternatives. One I thought of while visiting someone’s farm recently with spring water everywhere is running natural water flow under or over a building to cool the building from the water supply while using the same feed to the fish ponds so that the water isn’t wasted.
