Specifically developed to guarantee rapid and effective high-performance soundproofing for floors to counteract impact and footstep noise; complies with passive acoustic requirements specified by Prime-ministerial Decree 5-12-97.
MAPESILENT COMFORT is characterised by its simple handling and application and by its very compact thickness.
Ideal for creating floating screeds perfectly isolated from the substrate on which to install any type of flooring.
As a support to design engineers, MAPEI offers their free DataMapesilent® acoustic calculation software to help design and verify the acoustic and thermal performance properties of floors soundproofed with Mapesilent Comfort.
Ideal for:
Meeting the passive acoustic requirements of PM Decree 5-12-97, quick - simple installation, creating perfectly isolated floating screeds on which to install any type of flooring, being part of the design process to calculate expected acoustic performance properties.
It is recommended to contact our Technical Services Division for further information about Mapei soundproofing solutions and integrated systems.
Dry soundproofing system for floating screeds made from high density, closed-cell foam polyethylene sandwiched to a special protective film.
