When it comes to acoustic underlay, there are a few different options available. One of the most popular is green glue, which is a sustainable product with less odor and less impact on air quality. It is also easy to install due to its simple chemical composition, making it a faster and safer solution compared to two-part epoxy systems. In some cases, it may be necessary to glue a base coat.
For example, in a double adhesive installation, the base is glued to the subfloor with a removable adhesive.
Green glueis also used sandwiched between existing gypsum board and a new layer of gypsum board. However, if you are searching for something that will provide more sound dampening and blocking capabilities, Tecsound is the material we would recommend for filling two layers of acoustic plasterboard. Like acoustic glue, Tecsound is also viscoelastic.
When placed between two sheets of acoustic plasterboard, it has the ability to dampen sound energy and vibrations, as well as create a mass barrier that helps block sound in the air. Tecsound adds an additional 10 kg per m2 and is only 5.3 mm thick, making it much more effective than green glue which adds absolutely no mass. In addition, because acoustic glue doesn't evenly cover the entire wall, it doesn't create any type of hermetic barrier that helps block sound. Acoustic subfloor adhesive is also an excellent option for installing vinyl tiles and sheets with an acoustic rubber base. As a true pressure-sensitive adhesive (PSA), this adhesive has the advantage that it is placed both dry to the touch and semi-wet. When it comes to choosing the best adhesive for acoustic underlay, there are several factors to consider. Green glue is an excellent choice for quick installation and minimal impact on air quality.
