![]() With an STC value of 45, loud sounds can barely be heard through this insulation. It is used less often than fiberglass but is great for insulating exterior walls, basements, and crawl spaces.Ĭompared to fiberglass insulation, mineral wool has a much higher STC rating. Rock wool contains natural materials like basalt, whereas slag wool is made from blast furnace slag. Mineral wool is available as rock wool or slag wool. Fiberglass also has an STC rating of 36, which means it will cause loud speech to be muted. It is the most common type of batt insulation. It is the best option for insulating walls, as it was designed to be easily installed between unfinished frames.įiberglass insulation is made from extremely fine glass fibers. Fiberglass is the most popular type of batt insulation, but you can also find mineral wool, plastic fibers, and natural fibers.īatt insulation is best used for unfinished walls, floors, and ceilings. These are made from flexible fibers and are more widely available than other insulation. The most common type of insulation comes in batts or rolls. With a higher STC rating, insulation is more likely to block sounds. It is commonly used to calculate the soundproofing effectiveness of walls, ceilings, floors, windows, doors, and interior partitions. With an STC rating, you can know how many decibels are reduced with insulation. Sound Transmission Class, or STC, is a rating of how well a certain barrier blocks airborne sound. This is why the STC value is more indicative of an insulation’s performance level. If two products have the same r-value, they might not perform the same. Because this allows air movement around wall insulation, this completely changes the r-value. This does not have the same conditions as a real home, so this r-value is flawed.Īctual homes are not completely sealed off, leaving holes in the exterior that allow air to be conducted inside. When the r-value is calculated, it is measured through an artificial lab environment. Although this seems like an accurate measurement, many factors can change its result. R-value calculates how well a barrier can resist the conductive flow of heat. In the United States, this is the standard measurement to determine which insulation is the best, but this method has some flaws. The success of all insulation products is usually measured using r-value. Sound waves won’t be able to easily travel through this sound barrier. This is because sound waves travel through the air, so controlling airflow will also control noise levels.Īfter installing insulation in the walls, ceilings, and floors of your home, you’ll find that both airborne and impact noise is significantly reduced. The best type of soundproofing insulation will be able to stop airflow from moving between spaces. Insulation can absorb vibrations and decrease airflow, which is ideal for soundproofing. Control the Air FlowĪlthough insulation is commonly used to regulate temperature, it can also reduce noise. For these tight spots, be sure to pick up some soundproofing spray foam for existing walls. Its important to note that even the smallest of gaps will still allow sound in, undoing your hard work. ![]() ![]() The is guide will help you get your soundproof Insulation sorted.
