![]() ![]() It works by using a highly reflective film attached to one side of a base layer of plastic, cardboard, kraft paper, or oriented strand board. Unlike standard insulation, radiant barriers work by reflecting radiant heat away from your house. Radiant barriers can help prevent it from entering your home. Radiation from the sun is the main reason why your home collects so much heat in the summer. Instead, the radiation directly heats up the cup of coffee itself. That’s why there’s not a blast of hot air when you open the microwave door. If you put the cup in the microwave, the electromagnetic radiation isn’t heating up the air in the microwave. We’ll stick with the coffee example one last time. There is no direct contact between the heat source and material. We’re not talking about the kind of radiation that’ll make you glow, however.Įlectromagnetic radiation, like microwaves and visible light, causes radiant heat to travel through space. The final method of heat transfer is by radiation. Materials like metal and concrete are great conductors of heat, while wood and insulating material are bad ones. Standard insulation specializes in blocking conductive heat transfer by slowing it down as it goes through your walls. If you wrap your cold hands around that cup of coffee we mentioned earlier, the heat will travel from the coffee, through the mug and then to your hands. ConductionĬonduction is caused by physical contact, with heat transferring from one material to the other. Another example is when frozen food thaws quickly under cold running water. If you’ve seen steam rising from a hot cup of coffee, you’ve seen convection at work. This is because colder materials have more density than hotter ones. This causes the hot part to rise and the cooler one to sink. ![]() It occurs when there is a temperature difference between two parts of a liquid or gas. Heat transfer by convection involves the physical movement of liquids and gases. In summer, that heat will use those same areas to try to warm up the cooler air indoors. In winter, heat will try to escape from your home through the roof, walls, windows, and floors. Remember that heat always travels from high-temperature zones to those with lower ones. Understanding the three ways that heat can move will help you understand how radiant barriers and standard insulation works for your home. To get a better understanding, we first need to learn how heat flows. Keep reading to learn more about the differences between radiant barrier and insulation, and which is best for your home. That helps to make your garage (and home) cozier, without breaking your wallet. However, the best solution will usually be a combination of both. Radiant barriers and standard insulation are very different, but they help regulate temperature and humidity levels in your home.ĭeciding which is best depends heavily on what region of the country you live in, as well as other factors. Usually it comes down to a choice between a radiant barrier, or some type of fiberglass or foam insulation.ĭepending on where you live, your garage probably gets either really hot in the summer, or really cold in the winter. But deciding what type of insulation you need can be a challenge. I’ve been talking about the benefits of insulating your garage for a while. ![]()
