Van Insulation Fundamentals

Earlier than we soar into one of the best choices for van insulation supplies, it’s necessary to get a fundamental understanding of how insulation works and why you want it.

Warmth Switch 101

The purpose of van insulation is to maintain the within of your van at a continuing, comfy temperature as a lot as attainable. On sizzling days, this implies absorbing, redirecting, and reflecting warmth so your van stays cool. On chilly days, good insulation helps preserve the within of your van heat and comfortable.

There are three sorts of warmth switch mechanisms you want to bear in mind when selecting insulation supplies and constructing out your van:

1. Radiation
2. Convection
3. Conduction

Radiation

Radiation is the warmth that’s transferred straight from the solar into your van, usually by clear home windows. Radiant warmth will be nice for chilly, winter days, but it surely’s positively not preferrred throughout sizzling summer season temps.

Reflective window coverings or movie can be utilized on home windows to reduce the solar’s radiant warmth. Alternatively, if you wish to retain warmth in colder months, you need to use reflective surfaces inside your van to absorb the solar’s rays.

A reflective windshield sunshade can be a good suggestion to make use of when you find yourself parked or tenting beneath direct daylight.

Convection

Convection is the method by which warmth strikes by the air. Since heat air rises, having insulation on the roof of your van may help preserve warmth in throughout chilly temperatures. Alternatively, if you wish to cut back convection warmth in your van, putting in a ceiling fan may help transfer heat air out, maintaining temps cooler inside.

Conduction

Conduction refers to warmth that’s transferred by strong surfaces. When the solar’s rays heat the outside metallic panels of your van, a few of that warmth is then performed by the metallic and into your van, heating up the inside. That is the place a white van is more likely to keep cooler in comparison with a black van since white displays daylight and black absorbs it.

Conduction may also happen in the other way. When it’s chilly, warmth from inside your van will be misplaced by conduction to the skin by way of the metallic panels in case you don’t have correct insulation.

R-value

When you do numerous backpacking or tent tenting, you’re in all probability accustomed to the time period R-value since many sleeping pads have an R-value ranking. The R-value of a fabric signifies its means to insulate. The next R-value gives higher insulation whereas a decrease R-value permits for extra airflow and subsequently much less insulating energy.

Totally different van insulation supplies may have totally different R-values. When you plan on doing numerous winter tenting, you’ll need to use a fabric with a excessive R-value.

Condensation management

Some van builds embrace a vapor barrier which, in principle, prevents moisture from inflicting rust or mould and mildew. Nevertheless, a seal-tight vapor barrier is sort of unimaginable to realize, so as an alternative, we advocate selecting van insulation supplies that don’t retain moisture.

Greatest Camper Van Insulation Supplies

There are a variety of various campervan insulation choices obtainable they usually all have their professionals and cons. No matter materials you in the end select, it ought to have these 4 issues going for it:

1. Be immune to water, mildew, and mould
2. Be simple to put in in case you’re doing it your self
3. Be non-toxic
4. Be reasonably priced

Whereas there are numerous insulation choices on the market, not all are match for camper vans, so we’re narrowing it right down to the highest three van insulation supplies right here to chop to the chase and prevent a while: 3M Thinsulate, Havelock Wool, and foam boards.

3M Thinsulate

For my second Sprinter van, Outdoors Van used 3M Thinsulate for insulation. 3M Thinsulate is an artificial materials that’s non-toxic and straightforward to put in. It additionally has some sound dampening properties. Regardless of having a better price ticket and a barely decrease R-value of 5.2 than among the different choices, 3M Thinsulate is a transparent front-runner in discussions on Sprinter Van boards.

Mixed with further sound dampening materials, Outdoors Van estimates that they achieved an R-value of round 6 in my second Sprinter van. Placing numbers apart and talking from qualitative expertise, the insulation in my van appears very efficient. We do have a heater (extra on that in our information to van heating and cooling programs), however we’ve slept in sub-freezing temperatures on ski journeys and have had no points with temperature management or moisture.

Havelock Wool

One other rising front-runner for van insulation is sheep’s wool from an organization known as Havelock Wool. An all-natural materials, sheep’s wool has been touted as an eco-friendly insulation selection. It’s received a barely larger R-value than 3M Thinsulate (R-value of seven.2 for a 2″ thick batt) and it’s cheaper, has pure moisture-wicking properties, and in addition gives sound dampening.

Nevertheless, bugs love wool, so to be able to stop bugs, in addition to cut back flammability, Havelock applies a small quantity of boric acid to the sheep’s wool. That is thought-about non-toxic, in line with the Nationwide Pesticide Data Middle.

One last item to contemplate is that in comparison with 3M Thinsulate, sheep’s wool is reported to be barely messier on the set up, though Havelock’s insulation is available in 4’x1.3′ batts (sheets) to assist simplify set up.

Foam Boards

A ultimate possibility I’ll point out for van insulation is inflexible foam boards, like Polyisocyanurate. Polyisocyanurate foam boards have an R-value of 6 for a 1″ thick panel though thinner panels can be found as properly (R-5 for a 0.75″ panel – you don’t need to go any decrease than that if you’d like your van to be good and comfortable). These are extensively obtainable at {hardware} shops and are comparatively low cost making them funds possibility.

When you resolve to make use of a inflexible foam board, you’ll want to concentrate to any air gaps between the boards and ensure to fill them in with spray foam, 3M Thinsulate, or wool. In any other case, airflow will end in moisture build-up in these areas.

Additionally value mentioning is that Polyisocyanurate foam boards are created from plastic, so whereas they’re thought-about non-toxic and don’t off-gas, they aren’t essentially environmentally pleasant.

Making use of the fabric to even simply 25% of the within area will considerably cut back outdoors noise and vibrations in case you’re utilizing product particularly designed for this objective.

I counsel making use of sound-deadening supplies to partitions, the ceiling, the cab, the ground, wheel wells, doorways, and beneath the hood. 50 sq. toes is usually sufficient for the main areas of a panel van, however you’ll want extra if you wish to cowl all the inside.

Within the case of Outdoors Van, they usually use polyolefin, which is an upholstery with many makes use of reminiscent of carpeting and automobile interiors. It’s sturdy, immune to stains, mildew, and daylight, so it’s an awesome possibility for camper vans.

In my second van, Outdoors Van used a fabric known as Sil-Leather-based, which is fabricated from silicon.

Another choice to contemplate for upholstered wall panels is Sunbrella which is a sturdy out of doors material that’s simple to wash (though not as simple as wiping Sil-Leather-based) and doesn’t fade like numerous different supplies.

Different van lifers just like the look of wooden paneling. I don’t have private expertise with wooden, however many DIYers go for tongue and groove paneling. Others on a tighter funds simply use marine-grade plywood and paint over it.
