Inora Insulation
Walking, dancing, high heels, machinery... Without proper step sound insulation, sounds easily travel from one floor to another.
Instead of limiting the creation of sounds, let's enjoy an active life and let our shoes clatter!
With Inora Silent sound insulation, you create a pleasant and quiet living or working environment and ensure that the sounds of footsteps do not travel through the floor and walls from one floor to another.
Inora Silent is an effective solution for step sound insulation on concrete and wood floors. It is made from elastified EPS, a material that effectively dampens sound. Professional manufacturing, continuous production monitoring, and quality control ensure the product's high level of sound insulation.
The maximum permissible impact sound level according to building regulations is 53 dB. More attention is being paid to the sound insulation of building intermediate floors than before, also for living and working comfort.
When better sound insulation is desired, a floating floor structure with Inora Silent step sound insulation is an excellent solution. In this case, a sound level of even below 40 dB can be achieved. When improving sound insulation, for example, in connection with renovation, a change of about 5-6 dB is clearly noticeable. By increasing the thickness of the Inora Silent insulation by 1 cm, the sound insulation improves by about 2 dB.

-
For a floating floor structure to function properly, it is especially important that the structures on top of the flexible layer are completely separate from other structures.
-
When casting a concrete slab, care must be taken to ensure the slab is detached from adjacent structures by using a separation strip.
-
The flow of concrete mix between the Inora Silent impact sound insulation boards to the load-bearing structures is prevented by using a top slab casting shield.
-
Thin pipes can be placed horizontally in the floating floor, as long as their diameter is significantly smaller than the thickness of the flexible Silent layer.
-
The top slab must not be attached to any pipes that penetrate it. A separation piece is used for pipe penetrations.
-
The surface material of the floating floor must not be attached to surrounding structures or to pipes in the radiator network, as sound can travel through them to the floor above or below.
-
Thresholds should only be attached to the floating surface structure, not to the load-bearing frame.
-
Baseboards should be attached at least 1 mm away from the floor.
-
Adding weight to the top board and core material also improves sound insulation.
