![]() ![]() That’s why the material with R40 value is more effective at canceling noises than the same material with R15 value. The thermal resistance and noise blocking ability of insulation materials depend on their thickness. Noise Blocking PotentialĪll insulation materials, regardless of their type, dampen the outside noises. Read our guide to ventilation systems to explore different ways of keeping the air in your home fresh. In addition, the position of the room you’re insulating and the amount of sunlight it receives throughout the day can affect your decision to opt for R15 insulation or a material with a higher R-value. However, you’ll have to search for materials with higher R values if you want to insulate floors or crawlspaces in homes located in regions with cold climates.Ī two-layer R15 insulation structure should be sufficient to insulate floors, attics, and crawlspaces in regions with temperate climates. As we already pointed out, materials with R15 value are commonly used to insulate 2×4-inch walls. Heat Resistance CapacityĮven though climate plays a large role in the residential insulation selection process, the heat resistance capacity of R15 insulation makes it suitable for wall insulation in all climates. The R15 insulation types we’ve covered here are not the only options you have at your disposal, and you should consider reflective systems or fiber insulation if it matches your home’s requirements.īrowse through our guide to mini-split systems to learn how you can use them to control the air temperature in your home. The installation process can be overwhelming for DIYers because it involves using the equipment to distribute the material evenly. Blown-in insulation – This insulation type makes insulating the areas that are hard to reach easier.Rigid foam and foam boards – Although they’re suitable for interior and exterior applications, polyurethane, polystyrene, and polyisocyanurate R15 rigid foam boards must be covered properly to protect against fire and humidity.Its intended uses are the insulation of uncompleted walls, floors, or attics. It is usually made of fiberglass, mineral wool, and natural or plastic fibers. Blanket batt and roll insulation – This is the most common and least expensive type of R15 residential insulation.Let’s take a look at some of the R15 insulation types you can use in your home. That’s why you have to become more familiar with different types of insulation and the materials that are commonly used to make them.Īccording to the U.S Energy Department, there are nine residential insulation types that can be used to insulate anything from duct and crawl spaces to unfinished walls and ceilings. ![]() The abundance of insulation types and materials makes the R15 insulation selection process difficult. Creating two or more layers of R15 insulation allows you to double or triple the material’s thermal resistance.Ĭheck out our guide to furnace types if you’re looking for a whole-house heating solution. Hence, you should only choose the R15 insulation if it complements the U value of the segment you’d like to insulate. Simply put, the U value shows the combined thermal resistance of the bricks, wood, concrete, or other construction materials within a particular element. The U value is the combined thermal transmission coefficient of all materials that constitute a specific part of the house’s construction. Before you decide to use an R15 insulation material to insulate a specific segment of your home, you must first calculate the U value of that segment. The most common application of R15 insulation is the insulation of 2×4 exterior walls, but you can also use it to insulate floors, basements, and even attics. Finally, go through our guide to cooling systems if you’re looking for a way to keep your home cool. That’s why it’s hard to talk about a standardized set of features you should expect from R15 insulation, and you have to learn more about the properties of each material to understand how it performs in different conditions.Īlso, factors like the climate in the region where you live or the area of your home you want to insulate can affect your decision to choose one R15 insulation material over another. So, two insulation materials can have the same R-value despite having different characteristics. Therefore, despite being one of the most important characteristics of insulation materials, the R-value cannot be the only parameter you’re using to search for R15 insulation.įiberglass batt, mineral wool, and all other types of insulation materials can have a thermal resistance ratio in the range between 3 and 60. The thermal resistance shows you the insulation material’s ability to disrupt the flow of the heat. ![]()
