To be used in conjunction with vapour-permeable underlay membranes and roof protection films. Also for timber frame constructions with thermal insulation systems.
Safety
- Fabric reinforcement for extreme durability, tear-resistance and puncture resistance. Ideal for blow-in insulation
- Prevents moisture penetration of internal heat insulation and, therefore, the impairment of the insulating effect
Technology
- Three-ply vapour retarder with fabric reinforcement
- Environmentally friendly since it can be recycled
Universal use
Roofs, walls and floors.
Saves time and money
3-metre-wide vapour retarder for quick installation.
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.
