ACOUSTIC MATS
UNDER FLOOR COVERING
This is a product developed in order to attenuate impact noise when used under finished flooring such as LVT, vinyl, laminates and wood. It offers greater stability and durability for the cover, due to the lack of deformation.
Does not deform
Reduces environment reverberation as well as impact noises to lower flooring
Maintains efficiency in the long term
****************
The compression fluency test analyses material behavior in the long term when compressed by a specific weight. There was a loss of 7% in thickness under a 10 kPa load. This result ensures that the flooring and applied cover do not suffer damages during the useful life of the work due to system movements. The material was also tested in order to verify resistance to mediums with high alkaline content such as concrete. One may observe that the product is alkali-resistant and, therefore, inert to alkaline attack.
The material was also tested to identify their resistance to high alkalinity media content such as concrete. It can be seen that the product is alkali-resistant and hence an inert material to alkaline attack.
