Be sure you leave space for your vent fan if you don’t already have it installed! (3 Ways to Determine & Factors That Affect Price), Full-Time RV Living: 9 Benefits and Challenges. The gas heater inside the balloon heats the air, and so the air moves towards the top of the balloon. This is why it’s important to insulate your ceiling more completely than any other area of your van if you’ll be spending any time in the cold. A Frankenstein job will keep you just as warm. This can be accelerated with the vibration of driving around in your campervan, which can aid in the release of harmful particles into the air. [1]. When it comes to keeping the heat in or out, insulation is one of the most important steps you can do for your campervan conversion.

Chris and I tag-teamed this. This will help you at literally every stage in the process and will help you determine exactly how much material to buy. This means that water can slowly penetrate the foam board, making it less effective. It is also worth noting that the wool fibre itself is naturally biodegradable. Stand in the shade on a hot summer’s day for 30 seconds and you will know exactly what we mean. This feature used to an option, or standard on all-weather coaches. But rigid foam boards are much cheaper, more comfortable to work with, and almost as beneficial at insulating.

With the ceiling, we used purely Gorilla Tape, rather than deal with 3M90 dripping on the floor and having to hold the pieces in place until it set long enough to withstand gravity. 3M90 works like this: spray a complete coat on the surface you’re affixing it to. Although EPS is cheap and works fine as insulation, it has a higher K-value and will also degrade over time. If you want to do the absolute maximum when it comes to combatting high internal vehicle temperatures, using reflective foil cut-outs that sit inside your window frames will make a massive difference. Reflective bubble wrap insulation: A fairly new development in window insulation is a reflective bubble wrap material. There is also quite a lot of confusion when it comes to the correct type of insulation to choose from for your van build. That means there is less waste heading to landfills, as fibreglass products have extremely long life cycles.

Instead, this is better used for window coverings and in other small gaps of your van. There are many parent and subsidiary manufacturers that use Azdel in their RVs.

Your support means we can continue creating high-quality campervan conversion articles. Well, in simple terms, insulation slows and disrupts these types of heat transfer, keeping your van warmer in the cold, or cooler in the heat. warm air rising). Check out our feature article on outdoor kitchens to further explore them. In this article, we'll look at various ways to insulate an RV underbelly, as well as ways to minimize heat loss during cold conditions. The energy required to produce sheep wool compared to manmade equivalents is tiny – as most of the energy required is used to wash the wool before use. Fans also help moving heat around in winter. The main ingredient in fibreglass is glass. If we were close in numbers, we tended to round up, better to have too much than have to stop working and go back to Lowe’s and buy more (though we ended up doing that anyway). Polyisocyanurate, known as PIR, is one of the most popular insulation materials available. And for the price, it is not going to break the bank. This is the particleboard of the insulation world, made of scraps of recycled denim. There are much more effective and much less expensive insulation materials out there that have a much lower K-value.

It contains your inside climate-controlled air. Since heat rises, we’re not necessarily losing heat through the floor. K-value, also known as the Lambda value, Thermal Conductivity, and sometimes represented as the Greek letter λ, indicates the ability of such material to conduct heat. Assuming the door has the proper seal, this entryway is airtight against any heat leakage. If you want to stay comfortable inside your campervan, then insulating the vehicle correctly will have such a dramatic effect. RVs have similar R-values to traditional homes. It sort of combines all the best elements of the other foams and is Energy Star certified. It’s not the end of the world and we appreciate that we didn’t sacrifice more vertical space but still. Block foam is most often used. The basic concept is to use a material that prevents heat from flowing through it. [3][4]. Plus, it’s prone to mold and mildew with the natural condensation that will form in your van unless you completely seal it with a vapor barrier liner (VBL). Silicone-based caulking is the optimal substance to use. This produces closed-cell rigid insulation. Don’t skimp on glue: It’s easy to fall into the trap of wanting to save money (those 3M 90 cans are like $12 each!) The moisture in the air will eventually turn into condensation if the correct ventilation is not in place. Below, we have listed what you should look for when choosing the insulation materials for your campervan: A thermal bridge (also called a cold bridge), is an area that has a significantly higher heat transfer than the surrounding materials. Reflective bubble insulation is primarily a radiant barrier. The foams used can withstand high levels of heat during the laminating process. Radiant heat is primarily tied to van windows. That means it is comprised of particles that slough off that you’ll breathe in over time. If there are gaps, you can always just cut smaller pieces and fill them in, or use spray foam at the end. We didn’t actually do this until the frame of our bed was built! When you touch something cold, it feels like the cold is creeping into your hand, but actually, it’s the cold object drawing the heat away. This is then sandwiched between two high-performance aluminium foil facings. Insulation has everything to do with heat transfer, of which there are three types: Radiation: Heat transferred through air (i.e. It can then create a thermal bridge. Companies like Reflectix, make rolls of this insulator that you can cut to size.

The chemical makeups of these foams are different from that store brand cooler, and most are environmentally-friendly. When choosing the insulation for your campervan where space is limited, the insulation board is going to be the best material to use. Non-particulate van insulation is far safer for the lungs.
