Vapour-permeable, moisture-regulating, airtight and easy-to-install vapour retarder for interior renovations and attic conversions. To be used in conjunction with vapour-permeable underlay membranes and roof protection films
  • Embedded mesh for durability and tear resistance

  • Prevents heat loss caused by unnecessary airflow

  • Prevents moisture penetration of internal heat insulation and, therefore, the impairment of the insulating effect

  • Wütop DB 2 in combination with water vapour-permeable non-breathable membrane from the Wütop series provides year-round breathability for insulation and frame structure, creating a healthy indoor climate


Our products featuring the EMICODE label are low-emission/low in harmful substances. The EMICODE classification system awards labels to construction products that comply with the very stringent health and environmental requirements of recognised institutes.

DIN EN 13984



EMICODE EC1plus: Very low emissions: The EMICODE classification system distinguishes the environmental and health compatibility of construction products. The lowest-emission products bear the EC1plus mark.

Instructions

Installation instructions for between-rafter insulation


  • Fix Wütop DB 2 to the warm side of the heat insulation using a stapler (hammer tacker or hand-held stapler) and secure with battens

  • The smooth side always faces toward the installer

  • Vertical overlaps must always lie on a rafter

  • Ensure sufficient overlap: Horizontal overlap: at least 10 cm (overlap strip), vertical overlap: approx. 20 cm

  • All overlaps and stapled points must be given an airtight seal using suitable adhesive tape (Eurasol)

  • For airtight attachment to masonry, the membrane is bonded using Wütop film adhesive and secured with a clamping batten, if necessary

  • Take care not to damage the membrane during installation

  • Before the interior cladding is attached (gypsum plasterboard, wood panelling etc.), check again that the vapour retarder has been correctly installed and correct if necessary


Installation instructions for over-rafter insulation


  • Wütop DB 2 is ideal for use as a vapour retarder for over-rafter insulation

  • Installation: Same procedure as for between-rafter insulation

  • Please keep in mind: May be exposed to weather for max. 6 weeks


Installation instructions for renovation of old buildings


  • Sharp objects (e. g. nails) that protrude from the interior cladding into the rafter area must be removed to avoid damaging the vapour retarder

  • Wütop DB 2 is laid over the rafters from the outside with the fleece facing the room interior. Install with the smooth side facing outwards

  • All overlaps and openings must be given an airtight seal using suitable adhesive tape (Eurasol)

  • Recommendation: Secure Wütop DB 2 to the rafters using clamping battens

  • Bond joints at the eaves (eave beams or masonry) using Wütop film adhesive. Additional mechanical fixing with clamping battens is recommended

  • Wütop DB 2 vapour retarder must not be used to renovate interiors in which the humidity is continually over 60%

  • According to DIN 4108 part 3, structures that do not conform to standard construction methods must be verified with a calculation (dew point calculation). Therefore, the use of Wütop DB 2 for renovation work must be agreed upon beforehand by Würth Application Support
