Screed vibration dampening

SONOTIZ AT MonoFloat system.

Placed under the screed in one layer of 12mm, it forms a floating layer, effectively reducing vibrations and impact sound by up to 24 decibels. Versatile and durable, SONOTIZ AT ensures long-lasting acoustic excellence, making it the ideal choice for a quieter and more comfortable environment in various building types.

SONOTIZ AT TrioFloat system.

SONOTIZ AT in two layers with a mass-loaded membrane in between is placed under the screed, creating a floating layer that acts as a barrier against the transmission of vibrations and impact sound. This innovative design ensures that disturbances are absorbed and minimized, contributing to a quieter and more serene environment.

Features

In modern construction, effective soundproofing is crucial for enhanced indoor comfort. Often overlooked, the screed plays a significant role in sound transmission. Impact sound from footsteps and activities on the floor can disturb occupants. Addressing this issue is paramount for creating tranquil living and working spaces.

Classic under-screed SONOTIZ application method:

The top and bottom layers of the hydrophobic non-woven material provide a decoupling layer that helps protect against tile and cement cracking from floor movement.

After cleaning the surface of debris and dust, the SONOTIZ mat is placed lengthwise. It is necessary to cut the material with a margin so that its ends face the walls. So we measure the required length and add the dimensions of the “Edge” (the height is determined by the thickness of the screed plus at least 5 cm extra). We place the next mat along the first, making an overlap of about 5 cm and thus covering the entire floor. As a result, we get the appearance of a bowl into which the screed is poured (minimum screed thickness of 50 mm or 80 kg per m2). After levelling, the remaining excess must be cut and insulated.
