The flexing recreates the same sound on the other side. Sound waves hit the metal walls of your van. The R value measures how well a material stops heat from being conducted through it, but not how well it prevents convection or radiation. The unit of measurement most people use is the R value. Insulation is measured by how good it is at preventing heat from getting through. If you stop air from moving close to the hot metal on the inside of the van, it won’t be able to warm up from the radiated heat and then move that heat inside through convection. You stop convection by filling gaps so the air can’t be transported. That creates air currents to move the heat around inside the van. Warm air is lighter, so it rises and pushes cold air down. Once the sun’s heat gets radiated inside the van, it heats up the air in the van. Convection is where the heat is transported through the air.Again, anything that blocks the heat from being radiated will be a good insulator. The sun heated up the metal and now that heat is being re-radiated inside the van. You can put your hand near the inside van walls on a hot day and feel the heat being given off – radiated – even without touching them. Radiation is where the heat is given off by a surface.In other words, you use a substance that does not conduct heat well (some foams, for instance) to block the transfer of heat. You stop conduction by making a thermal barrier. The heat from the sun gets spread from the outside to the inside of the metal van walls by conduction. Heat in one part of the body spreads to other places fast. The van’s metal body is a very good heat conductor. Conduction is where the heat moves through a substance.Think of the situation where the sun is shining on the outside of your van. Heat moves through conduction, convection, and radiation. You often need different types of insulation for heat and sound. Insulation makes sure the heat stays where it should – inside or outside the van – and dampens the sounds like road noise to make the van quieter. There’s some factory sound damping stuck to the wall panels, but the van can still sound like being inside a big oil drum. Sound enters through the floor and wall panels and bounces around inside the van. The climate control in the dash can’t keep up with the massive area of the van. During the winter it loses its heat quickly to the outside. Insulation is supposed to stop or slow down the flow of heat or noise.Īn empty Sprinter is a big metal oven in the summer, trapping and amplifying the heat of the sun. Want to jump to a specific section? Here’s the index: What's insulation for?

We could have chosen foam, fiberglass, wool, or even recycled jeans instead. We chose to insulate our van with Thinsulate and Low-E reflective foam/foil.
