MATERASSINO CS: UNDER-TILE SOUND PROOFING ACOUSTIC UNDERLAY
MATERASSINO CS: UNDER-TILE SOUND PROOFING ACOUSTIC UNDERLAY
Materassino CentroStorico is an under-tile sound proofing acoustic underlay mat that is applied between the screed and the floor finish (tiles, wood, etc.), reducing the transmission of impact noise (footfall noise and falling objects) transmitted to storeys below; sound proofing with Materassino requires a minimum thickness, without the need to realize a floating screed.
The flexible acoustic underlay Materassino is applied by gluing it on both sides: a first gluing to adhere the underlay to the substrate (screed, or existing flooring in certain conditions, etc.) and then a second gluing to stick the floor finish (tiles, wood, etc.) to the Materassino underlay.

CHARACTERISTICS AND ADVANTAGES
AN IDEAL COMPLEMENT TO LATERLITE SCREEDS AND CONCRETES.
The Materassino acoustic underlay is compatible with Laterlite’s range of lightweight and technical screed mortars and concretes, for acoustic insulation solutions that are both slim and effective.
SIGNIFICANT IMPROVEMENT IN SOUND INSULATION AGAINST IMPACT NOISE.
Significant increase in the floor impact sound performance ΔLw* = 16 dB at very low thickness.
EASY TO APPLY
The acoustic mat is applied using with the same tile adhesives or glues used for floor finishes and is carried out with a traditional technique.
IDEAL IN CASE OF LIMITED AVAILABLE THICKNESS
-The application of the acoustic matting directly under the flooring makes it possible to considerably reduce the thickness of the solution: Materassino is therefore ideal for renovation or refurbishment work where available thicknesses are often low. -It is also very useful when replacing a flexible and resilient finish, such as carpet or vinyl, with tiles.
FIELDS OF USE
-Acoustic insulation against impact noise between the screed and the flooring in intermediate floors. -Direct laying of any flooring (ceramic tiles, adhered or floating wood floorboards and similar) using the usual adhesives. -Ideal in case of low available thickness and in the renovation of existing slabs and floors where there is not enough thickness to realize a floating screed.
