Wütop® DB 20 is a vapour retarder that is water vapour permeable, airtight and particularly easy to install, designed for use in interior fit-outs and loft conversions in conjunction with water vapour permeable roofing underlays. Also suitable for timber-frame constructions with ETICS.
Safety
- The fabric reinforcement is extremely durable, tear- and puncture-resistant. Also ideally suited to blow-in insulation
- Prevents moisture penetration of internal heat insulation and, therefore, the diminishing of the insulating effect
Technology
- 3-layer vapour retarder with fabric reinforcement
- Recyclable
Suitable for universal use
Roofs, walls and floors.
Saves time and money
Due to the quick installation of the vapour retarder, which is 3 m wide.
Installation instructions
- Fix Wütop® DB 20 to the "warm" side of the thermal insulation with stapler (impact staple gun art. no. 0714 854, 0714 811 or hand-held stapler art. no. 0714 834) 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 overlapping and stapled points must be sealed airtight with suitable adhesive tape (art. no. 0992 700 050).
- For airtight connection to masonry, the strip is bonded using Wütop® film adhesive (art no. 0893 700 100, 0893 700 110) and also secured with a clamping batten if necessary.
- Take care not to damage the membrane during installation.
- Before the interior cladding (plasterboard, wood panelling etc.) is attached, check again that the vapour retarder has been correctly installed and remedy if necessary.
Insulation on rafters
- Wütop® DB 20 is ideal for use as a vapour retarder for insulation on rafters.
- Installation: Same procedure as for between-rafter insulation.
- Please keep in mind: May be exposed to weather for max. 6 weeks.
