The debate as to whether acoustic sealants are better than thermal insulation is one that is hotly contested. There are pros and cons with both materials that make them ideal for certain applications and less than ideal for others. Each has unique properties that make them essential for many different types of jobs.
Acoustic sealants are flexible materials that provide soundproofing for both interior and exterior applications. It’s ideal for tight spaces such as gaps between the sub floor and framing and around electrical outlets. Their weather resistant capabilities also make them ideal for marine applications. Acoustical sealants can are an effective way for you to limit noise penetrating floors or walls between rooms.
Thermal insulations, unlike acoustic sealants, are designed to provide thermal protection against the elements. These materials work by reducing the rate of heat transfer from warmer areas to colder areas. Some of the most common materials used in thermal insulation are fiberglass and cellulose materials. Depending on the type, thermal insulation is installed using a spray-in method or rolled out using paper backed batts.
