IMPACTODAN
Cross-linked polyethylene foam membrane for acoustic insulation of a floating screed from a structural concrete floor.
Product variations:
EPD S-P-01924
IMPACTODAN is a cross-linked polyethylene foam sheet. Its closed cell structure provides exceptional physical and mechanical properties. It is used for acoustic insulation of deck impact noise in buildings. It presents high resistance to fatigue and is easy to install. Its use is guaranteed by the DIT N. 439 from the Spanish building science institute “Eduardo Torroja”.

Scope
- Airborne and impact sound insulation in floor slabs between different users in public or private residential buildings.
- Sound insulation in the renovation of floors in dwellings.
- Complements the insulation of floating floors for low, medium and high frequencies in all types of commercial premises in tertiary buildings or in commercial ground floors of commercial buildings.
Advantages & Benefits
- Impact sound insulation, L'nT, w<65 dB
- Acoustic insulation to airborne noise DnTA>50 dBA, for IMPACTODAN® 5 DnTA>55 dBA, for IMPACTODAN® 10
- Vapour and dampness barrier.
- Good thermal conductivity, ensuring thermal comfort.
- Easy and quick to install.
- Long life expectancy.
- High flexibility, avoids the use of filling mortars.
- Low thickness with high acoustic performance.
Indications and Important Recommendations
- As the floating floors are made of damp-proof materials, the setting times of the mortars are longer, and it is recommended that the mortar be walked on 15-20 days after it has been poured.
- Before pouring the mortar, check that the material of the most superficial layer is completely continuous over the entire surface, that it overlaps on the vertical walls, and that it completely envelops the pillars and installations that go through or across the floor.
- The floating mortar must be strong enough to prevent cracking. (See SPD No. 1.3).
- In systems where the partition walls are floating on strips, the partition wall must be grouted with the internal floating partition walls, thus giving stability to the system. (See SPD No. 2.1)
- This product is part of a Sound Insulation system, so all the documents referred to in the Danosa Solutions Manual, Sound Insulation Installation "Singular Point Details" (SPD), D.I.T No. 439, as well as the rest of the Danosa documentation, must be taken into account.
- Door frames must not pierce the floating mortar completely (see D.I.T. 439 figure 13).
- It is recommended to be used if the compression layer of the slab is very uneven.
- If self-levelling mortars are used, the IMPACTODAN sheet must rest completely on the floor, being perfectly extended without forming wrinkles.
