Cross-linked polyethylene foam membrane for acoustic insulation of laminated or timber floors.

Product variations:
Acoustic Insulation
CONFORDAN® ECO is a flexible, chemically cross-linked polyethylene film, closed-cell on one side, which gives the product an elastic internal structure. It's designed to insulate residential wooden floor systems and complements the IMPACTODAN system. Compatible with underfloor heating.


  • Damp-proof and separation barrier for floating floor finishes.
  • Complements the IMPACTODAN® system.
  • Wooden flooring systems in dwellings.

Advantages & Benefits

  • Vapour and dampness barrier.
  • Good acoustic insulation against impact noise.
  • Compatible with underfloor heating.
  • Great durability.
  • Inexpensive, easy and efficient installation.
  • The aluminium sealing tape reduces the static charge.
  • Impact noise improvement ΔLn = 17 dB.
  • Optimum chemical and thermal resistance.

Instruction for Use

Preliminary operations
  • Before starting the works, the materials necessary for the execution of the work must be gathered, which are:
Staking out equipment
  • The installations must be completed before laying the CONFORDAN ECO sheet.
  • Any unevenness of the floor of more than 3 mm within 1 m must be levelled out beforehand with ARGONIV 020 ELITE levelling compound for thicknesses < 10 mm or ARGONIV 120 ELITE for thicknesses > 10 mm.
  • Fixing equipment
  • Aluminium ADHESIVE TAPE should be used to fasten the sheet to each other and to any point on the building site such as slabs, pillars, walls or any other structural element that functions as an electrical earth connection.
  • Unroll the CONFORDAN ECO in the longitudinal direction of the boards, cutting the necessary size with a cutter.
  • It is advisable to overlap and seal with CONFORDAN ECO adhesive tape to give continuity to the insulation and prevent the passage of dampness.
  • Install the floating floor according to the manufacturer’s instructions or pour the mortar.

Indications and Important Recommendations

  • The floating mortar must be strong enough to prevent cracking. (See SPD No. 1.3).
  • The skirting boards should be at least 15 mm thick to cover the expansion gap and to avoid creating an acoustic bridge, they should be left with a small gap that can be created by means of a silicone bead.
  • The planks must remain for at least 48 hours acclimatising to the room in which they are to be installed at an ambient temperature of at least 17°C, relative dampness not exceeding 70%.
  • 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.
