CONFORDAN 900 is a two layer product made of a self-adhesive high density bitumen membrane thermally bonded to a cross-linked polyethylene. CONFORDAN 900 acoustically works as shock absorber in mass-spring-mass system in floor, and removing resonant frequencies in plasterboard system.
Advantages & Benefits
- Offers minimal irregularities to exisiting flooring.
- Vapour barrier.
- Good resistance to compression.
- Reduces the noise of the platform itself. Lower volume.
- Long life expectancy.
- High resistance to tearing.
- Inexpensive, easy and efficient installation.
- The aluminium sealing tape reduces the static charge.
- Improvement of airborne sound level between rigid elements ΔRA>4 dBA.
- Improved impact noise level under floorboards ΔLw>22 dB.
- Improved impact noise level under 5 cm mortar ΔLw>21 dB.
- Optimum chemical and thermal resistance.
- Feeling of comfort in the tread.
- Loudness of 70 sone.
Indications and Important Recommendations
- The floating mortar must be strong enough to prevent cracking. (See SPD No. 1.3).
- The facade cladding in a building must end at the dividing wall between different users. See SPD 2.1
- Installations or elements liable to cause vibrations inside the partition walls shall be protected by cross-linked PE shells. See SPD 2.3
- The structure's anchorages must not be fixed to the building structure except on the roof. See SPD 3.2
- In order for the system to be perfectly determined by the insulation, no unwanted lateral transmissions must occur.
- Set back the partition wall on the pillars.
- Impact sound insulation must be used (e.g. Impactodan System) See AA01 sheet.
- It will be taken into account that this product is part of a Sound Insulation system, so the Danosa Constructive Solutions Catalogue, Sound Insulation Commissioning must be taken into account. "Details of Singular Points" (SPD), as well as the rest of the Danosa documentation.
- Isolated sewage disposal systems with FONODAN BJ or ACUSTIDAN. See BAJ1 and BAJ2 sheet of "Danosa Sound Insulation Solutions.
