False ceiling on a Concrete Floor.
Improvement for high performance floors
The reinforced concrete floor is increasingly used, especially for its structural performance. Thanks to its mass, the acoustic insulation can be very good and with the right engineered solutions can achieve the highest standards and a superior acoustic comfort.
With the application of an acoustic false ceiling, fixed with acoustic hangers and pre-assembled insulating boards, a disconnection is created, increasing the airborne and impact noise insulation in just a limited space.

False ceiling on a hollow concrete floor.
Improvement for typical residential floors in multi-storey buildings
Hollow core slab is a very common floor used in building construction, capable of optimizing the self weight and enhancing the load capability. When completed with the structural screed, this floor can grant a good sound insulation, however the installation of an acoustic false ceiling improves the acoustic performance to an excellent level. The use of pre-assembled Isolgomma acoustic boards, installed on acoustic hangers, is a simple and very efficient solution to reach the best insulation values.

False ceiling on a timber joists floor.
Sound insulation below the beams
The timber joists floor has weak sound insulation properties, with a particularly critical behavior at low frequencies. Together with an efficient acoustic treatment on top of the floor, the use of a false ceiling below the beams is crucial to reach the best insulation. The use of REDFIX acoustic hangers with Isolgomma pre-assembled acoustic boards, reduces the footfall noise and sensibly improves the overall airborne sound insulation.

Sound insulation between the beams
On an existent timber joists floor, improving the sound insulation with a full false ceiling is not always possible. However in particular situations a good solution can be achieved also working in the space between the beams. Closing this space with Isolgomma pre-assembled acoustic boards and filling the cavity with sound absorbing polyester fiber panels, the overall acoustic insulation of the floor can significantly increase, with a minimal and pleasant solution.

Suspended ceiling.
The suspended false ceiling is typically used for tertiary sector buildings. It is a very interesting solution as it allows, in the large space left as a gap between the floor and the finish, the insertion of ducts, even large ones, dedicated to cooling, heating and air treatment. It also allows the passage of all other types of installations before finishing. For a proper functioning of the solution it is important for the metal structure to be fixed to the floor by means of Redfix insulated hooks that allow the best management of the propagation of possible transmissions of vibrations through the structure of the building.
