AcoustiTECH is the only manufacturer that can ensure compatibility of components under the floor by offering both adhesives and acoustic membranes under the same brand. Lab and on site tests were made to ensure the stability of our products and avoid delamination, the hollow spots or other problematic situation. Our expertise goes beyond the acoustic products, providing you with support for your project (analysis of the plans, proposed various solutions to meet your needs and budget, etc.).

This acoustic result (IIC) is a projection of the results obtained from acoustic tests in different floor assemblies. In a similar building with a structure having the same characteristics, it may be that the acoustic performance differs depending on the quality of execution of the installation work, the surfaces and the selected materials.
