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
