![]() Low bids or time overruns can quickly create financial challenges for your business. And, in an industry that relies on tight profit margins even at the best of times, it is one more area in which you need an excellent grasp of costs plus clear control over the process. It’s one more aspect of a complicated job. Most drywallers purchase the insulation materials for residential jobs, whether or not they choose to handle the labor themselves. If the studs in your project are closer together (or you are dealing with large expanses of less energy-efficient glass), you may need to use a more efficient and probably more expensive insulation material to achieve the desired results. Another important factor to consider is that every stud provides an easy route for heat and cold to come and go unimpeded. For example, compressing two layers of batting into the space intended for one layer will not double the R-value. Manufacturer R-values apply only to properly installed insulation. There are many factors that come into play when using R-values to find materials that will meet codes or builder specs. * Making the Right ChoicesĬlearly, drywall needs help when it comes to properly insulating a wall. However, it is significantly less than materials that are commonly used for insulation. This is similar to building materials such as siding, concrete, dirt, face brick, particleboard, wood and single-pane glass. ![]() ![]() R-values for Drywall - How Do They Compare?ĭrywall has a relatively low R-value - about 0.45 at ½” thickness. However, since people tend to associate higher numbers with better performance, this proved to be confusing and R-values were created in the 40’s to make it easier to understand which insulating products were more effective. The lower the U-value, the better the insulation properties of a material. U-values were actually the industry standard for designating insulation efficiency until 1945 and are still required for some energy modeling programs and code calculations. Once testers determine a U value, the R-value is simply the inverse or 1/U-value. The R-value is simply the opposite - a description of a material’s resistance to conducting heat. The U-value, also known as the U-factor, describes how well a building material conducts heat. Researchers do not physically measure R-values. In other words if you sandwich a layer of R-value 10 material between two layers of R-value 1 material, the combination has an R-value of 12. R-values also are additive for an assembly of materials. Three inches of blown insulation will have a higher value than two inches of the same material. R-values increase with the thickness of a specific material. The higher the R-value, the greater the thermal resistance and the better the insulation performance of the material. ![]() R-values are used in the building industry to indicate how well materials insulate. It measures a material’s capacity to resist the flow of heat and cold, also known as its thermal resistance. R-value is a shortened term for Resistance value. Frankly, while drywall is a wonderful material for many reasons, it isn’t much of an insulator. Materials that offer better thermal resistance are naturally better insulators than those with lower thermal resistance.
