How to keep your RV, Caravan and Bus cool

Living in your caravan, RV, or bus during summer can be challenging as they can become unbearably hot. With minimal insulation in the roof, solar heat transfers easily into the living space, creating uncomfortable conditions. This often forces you to desperately look for shade and crank up air conditioning, leading to higher energy costs, or endure the heat. Additionally, insufficient insulation can lead to condensation between the roof and interior paneling, fostering mould growth and other structural issues.

For other modes of transportation, such as trucks, trailers, and shipping containers, the challenges are similar. In trucks and trailers, heat buildup compromises cool and cold storage, increasing fuel consumption and the risk of stock damage. Shipping containers face heat-related structural damage and uncomfortable working environments.

A robust solution lies in using a high-quality thermal insulation coating like Super Therm® Ceramic Solar Heat Block Coating. To choose the best coating for your needs, consider these key factors:

• UV and Weather Resistance: Ensure the coating is designed to withstand intense UV exposure and harsh weather conditions without degrading. Super Therm® excels at providing long-term protection against these elements and blocks 97% of the UV rays plus designed as a tough insulation coating its created for the toughest environments on the planet.
• Durability: Look for coatings that offer a long lifespan without cracking, peeling, or fading. Super Therm® is known for its industrial-grade durability, performing effectively for decades. Even the Las Vegas International Airport utilises Super Therm® because of its outstanding performance and durability in a tough desert environment.
• Ease of Application: Opt for a product that is straightforward to apply using common tools like rollers or brushes, eliminating the need for professional assistance. Super Therm® is user-friendly and versatile, compatible with various surfaces like aluminium and fibreglass. Two simple coats by brush and roller and you’re done, water-based, safe and instant, passive performance blocking heat.
• Thermal Insulation: The primary purpose of a reflective heat block coating is to block and insulate against heat. Super Therm® reflects and blocks 96.1% of solar heat, significantly reducing internal temperatures and enhancing comfort, reduces humidity all while lowering energy consumption. It works the same on any surface including your caravan and RV.

Many RV, caravan and bus owners in Australia and transportation operators worldwide have relied on Super Therm® Ceramic Solar Heat Block Coating to address these challenges. Its proven effectiveness in heat reduction is backed by case studies from diverse applications, making it a trusted choice for a cooler, more efficient environment in caravans, RVs, buses, and other vehicles.

RV Super Therm Case Study

Super Therm® on a Florida Motorhome RV

• Average internal temperature improvement was 5.6°c – 12%
• 2 hours to pressure clean the roof the day before and fully dry
• 4 hours for two employees to apply the coating 87m2 by roller
• The exterior surface temperature was 73°c…after application dropped to 30°c (59% improvement)
• Roof surface temperature of a similar mobile home with a white elastomeric paint was 51.6°c
• The motor home owner reported that she had not turned on her air conditioning since the day the roof was coated
• SJHP’s assessment is that Super Therm® works well and meets their purpose and budget. It was relatively easy to apply and does not require significant application skills, other than normal diligence and care. They were very impressed with the immediate temperature changes after application.

Bus Super Therm Case Study

As an example, Super Therm was applied to a bus in Mexico and here’s the results. Before coating with Super Therm®, the roof’s temperature and the interior temperature were much higher.

• After application of Super Therm® the roof’s temperature was significantly lower than before application. Without Super Therm® the roof’s temperature rose to 90.1ºc, after Super Therm® the temperature only reached 46.2ºc. This proves Super Therm’s strength in reducing heat transfer (Refer to Graphic 2.4).
• As a direct result of application of Super Therm®, the temperature inside the bus decreased 8ºc, always tending to equalize itself with the outside temperature during the test (from 7 a.m. to 1:30 p.m.) (Refer to Graphic 2.5).
• The Super Therm coated roof absorbed 46.27% less heat than the non-coated roof (Refer to Graphic 2.4).
• With Super Therm®, the Thermo King unit only needed 33.4 minutes to reach 29ºc, 45% less running time than without using Super Therm®. (Refer to graphic 2.6).
• Given the need to put the bus back onto its route, the testing and temperature results taken from the Super Therm® bus were done within one day of application. Super Therm® typically takes 7-10 days to fully cure and thus even more favorable results might be seen after full cure.
• The Thermo King unit coated with Super Therm® became 30.5% more efficient.

Super Therm® ceramic coating saves fuel for food-hauling fleet

• Super Therm® cool-down time was cut by 1.75 hours or 44%
• 20% less fuel on the outbound “hot” haul
• 29% less fuel on the return “cold” leg
• Long-term savings at 200 to 250 trips a year, the sav­ings could total $2,500 times by 20 years $50,000 savings.

Pacific Shipping & Trucking of Denver moves truckloads of baked bread from Denver to Phoenix, then returns to Denver with ice cream, explains Keith Robertson, the fleet’s owner and president. Bread is maintained at (27°C) 80°F, but ice cream must stay frozen at (-28°C) -20°F – “extreme heat to extreme cold,” he says. It’s a drop-and-hook operation, with trailers full of bread left at docks in the usually hot southern Arizona city while empty reefer trailers wait nearby.

A driver backs his tractor onto an empty, then starts the reefer unit to begin cooling down the trailer’s interi­or or so it can take on ice cream. Temps inside the trailer can be (48°C) 120°F or more, and it’s got to be cooled to below zero. “It was taking us two and a half hours to get sitting out in the sun to get to minus 10 – from there they can start loading – then,” Robertson says. “Now it takes 45 minutes to an hour,” so the reefer runs less and burns less fuel.

What to do about a caravan, bus or RV? 

In homes and buildings adding a light coloured roof helps reflect heat right where it’s beating down on you. This is the same for your caravan, bus or RV. Adding a Cool Roof to your transportation is like being under a shady tree. In fact a Super Therm® Cool Roof does more than block 95% of the solar heat from the sun, it also:

• Lasts well over 20 years – no cracking, flaking or peeling
• Dramatically reduces energy consumption and costs
• Improves human and animal comfort
• Single coat application (no priming)
• Easy to apply, safe and water based
• Works while dirty
• No priming needed
• Reduces CO2 consumption through energy reduction
• Fireproof class ‘A’ rating; won’t burn
• Blocks 50-68% sound
• Prevents thermal contraction and extends roof life
• Tested and blocks 99.5% infrared heat
• Proven globally for over 30+ years
• Only ceramic solar heat block coating developed with NASA
• Over 9.3 million square metres applied across Japan

Cool Roofs are the next generation of heat protection. Governments and companies around the globe are turning to cool roofs and the Tesla of Cool Roofs performance is Super Therm®.

Blocking the initial heat load is the “key” to controlling heat load and flow into or out of a building structure!
