WATERPROOFING, INSULATION & MORTARS

In order to show the acoustic properties of the products, DANOSA has made tests with their products. The Sonodan plus Auto-adhesive results are the following:

The acoustic certifications are a consequence of several tests in homologated laboratories.
It complies with the Technical Building Code requirements for premises used in machinery rooms according to the DANOSA’s Sound Insulation Solutions Catalog, files AA-03; AA-24 y AA32.

Acoustic isolation of music venues in tertiary buildings or located in commercial low-rise residential buildings.
It is used in the acoustic treatment of machine rooms in residential buildings or any other place that has the need to behave well to low frequencies noise, in the rehabilitation of walls between different users. And also in new works to increase the insulation in buildings and be able to install high quality audio-visual systems (Home Cinema).

- Good behaviour of impulse noises of low frequencies.

- By using a cross-linked polyethylene in the first layer, we make the product attenuate the impulsive noise.

- The combination of membranes forms a resonator that attenuates low frequencies.

- As the first layer is very flexible, it allows continuity in difficult encounters such as corners and pillars. Getting better acoustic insulation at low frequencies.

- Sealing is ensured by installing the second counterweighted layer, improving the insulation at low and medium frequencies.

- Due to its high level of tensile strength it can be installed mechanically.

- The self-adhesive sheets facilitates the placement of the second layer, constituting in this way the membrane resonator, avoiding the inconveniences of gluing and obtaining a higher efficiency in its placement (m²/hour/man).

- With little thickness achieves high acoustic performances, leaving the premises with more useful surface.

- Due to its high performance, lighter masonry finishes can be used, making the solution cheaper and its performance.

- Due to the dimensions of the panel it is easier and faster to install on the roof.

Previous operations:
The vertical and horizontal walls must be plastered with 1.5 cm of plaster. Before applying the product, the plaster must be completely dry.If, for reasons of work speed, it is not possible to wait for the plaster to dry, we recommend using a laminated gypsum formed by N15 plate as a sealant for the wall.The installations that go through the elements once they are insulated will be made a notched prior to the insulation of the wall.

SONODAN PLUS Autoadhesive installation:
On the SONODAN PLUS Self-adhesive pallet, the first layer of SONODAN PLUS Self-adhesive is placed on top, which is the first to be installed. Below is the second layer, which will be installed once the first layer is fixed.

On the wall:
The first layer of SONODAN PLUS Autoadhesivo is installed against the support, so that it presses the gray polyethylene while the membrane is visible. You can choose two methods to fix the first layer:
- Mechanical fixation
It is fixed with staples or fixings for DANOSA Insulation (performance of 4 units per panel). Once the piece is placed squarely with the parameters, one person will hold the upper part, while another will perform the first two mechanical fixings, then one person will be released and the other will continue to apply fixations.
For this, a hammer drill and diamond drill are used, which will perforate both the panel and the partition wall, then insert the cue and present the spike. Finally, the spike is hit with a hammer, being embedded in the material.
- Fixation by adhesive
A layer of GLUDAN Acustic 1 contact adhesive is applied to the wall using a short pile roller.
The performance for a perfect adhesion is 125 gr / m2.
In the same way and on a clean surface where the first layer of SONODAN PLUS Autoadhesivo has been deposited, another layer is applied with the same performance on the grey polyethylene. Once about 15 minutes have passed the first layer is pasted on the wall. (The total yield is 250 gr / m2).
- To start, choose a corner presenting the panel so that the largest dimension (1.2 m) is in height and will be fixed according to the chosen method.
- Next, half of the first layer of SONODAN PLUS Self-Adhesive is put on one wall and the other half on the adjoining wall, in this way it is possible to give continuity to the membrane and the counterbalance of the second layer is easier.
- It continues placing first layer panels so that they are good with the adjacent one.- Remove the non-stick plastic from the first layer of SONODAN PLUS Autoadhesivo once fixed to the wall according to the chosen method.
- Present the second layer so that the membranes meet and the mineral wool is seen. _To start installing the SONODAN PLUS Autoadhesivo second layer we remove the non-sick plastic and placing the panel against a corner, so that the smallest dimension (1 m) is in height.
- Press the second layer against the first.

On roof:
- The first layer of SONODAN PLUS Autoadhesive is installed against the support, so that it presses the grey polyethylene while the membrane is visible. You can choose two methods to fix the first layer:
- Mechanical fixation (as described on wall)
- Fixation by adhesive (as described on wall)
- To start, choose a corner presenting the panel so that the largest dimension (1.2 m) is in width and will be fixed according to the chosen method.
- Then, half of the first layer of SONODAN PLUS Autoadhesive is put on one wall and the other half on the ceiling, in this way the membrane is given continuity and the second layer is counterbalanced.
- It continues to place panels of the first layer so that they are to test with the adjacent. - Remove the non-stick plastic from the first layer of SONODAN PLUS Autoadhesivo once fixed to the wall according to the chosen method.
- Present the second layer of SONODAN PLUS Self-adhesive so that the membranes meet and the rock wool is visible.
- To start installing the second layer of SONODAN PLUS Self-adhesive start by removing the non-stick plastic and placing the panel against a corner, so that the smallest dimension (1 m) is in length.
- Then press the second layer against the first one. For security this second layer of SONODAN PLUS Autoadhesive is fixed with fixings for DANOSA Insulation, its performance being 1 unit per panel. _Note: DPS: Manual Implementation of Acoustic Insulation. Details of Singular Points.

- The contact tails used to stick the product must have little solvent content, because if not they can affect the factory bonding. - On the roof, the shock absorber bell can be used as additional fixation.
- In order that the obtained result (acoustic performance) is influenced as little as possible by the constructive solution, the following considerations must be taken into account: - The plastering of façade in building must end in the dividing wall between different users. See DPS 2.1 – Impact noise insulation must be used. See Manuals of Acoustic Insulation Solutions from AA01-AA04. - If the heating installations were central or of water intake, decoupling by cross-linked polyethylene shell of the same. See DPS 1.2 - The floating ceiling cannot be drilled with installations proposed in commercial premises. See DPS 4.4 and tabs AA32 and AA33 - The partitions must have a plaster of at least 1 cm. See DPS 3. - Do not anchor the partitions to structural elements (except roof in homes) such as pillars and facades. To maintain the stability of the system, the transom element must be encased in the interior floating partitions. - The evacuation facilities that run through the commercial premises, must be isolated with ACUSTIDAN (see file AA51) and protected with constructive elements. The steps of installations sealed with high density resilient materials. See DPS 1.2 - Never connect the smoke outlets to the ventilation chimneys. - Do not drill with installations the floating roof in solution of commercial premises. Create technical sockets for electrical panels that are located on walls. See DPS 2.3 and DPS 4.4 - If you use a battery drilling machine (never with an electric cable connected to a network), you can wet the drill in water. This prevents the drill from becoming embedded with the asphalt. - It will be taken into account that this product is part of an acoustic insulation system, so the DANOSA Constructive Solutions Catalogue must be taken into account. Tabs AA15, AA24, AA25, AA32 and AA33., Implementation of Acoustic Insulation. Details of Singular Points (DPS), as well as the rest of the DANOSA documentation.
