Moisture-variable vapour retarder with the advantages of polyester technology

WÜTOP Thermo Vario SD is a vapour-permeable, moisture-variable and airtight vapour retarder for the renovation of old buildings, interior finishing and loft conversions. When combined with WÜTOP non-breathable and breathable membranes and EURASOL adhesive tapes, it can be used to create modern airtight and windproof structures.



Safety


Polyester is an extremely weather-resistant material, provides a high degree of protection against UV radiation and is temperature-resistant up to 100 °C.



Technology


Two-layer vapour retarder consisting of moisture-variable polyamide with stabilising polyester fleece.



For universal use


  • Roofs, walls and floors

  • Renovation of old buildings from the outside (sub and top processes)

  • Damp new buildings (with adequate ventilation)


Time and cost savings


  • Installation grid for easy and quick installation (10 x 10 cm)

  • Very robust and tear-resistant thanks to polyester fleece backing

Instructions

Installation instructions for between-rafter insulation


  • Fix WÜTOP Thermo Vario SD to the warm side of the heat insulation using a stapler (hammer tacker art. no. 0714854, 0714811 or hand-held stapler art. no. 0714834) 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.

  • Airtight bonding with a suitable adhesive tape (art. no. 0992700050) is recommended for all overlaps and stapled points.

  • For airtight attachment to masonry, the membrane is bonded using WÜTOP film adhesive (art. no. 0893700100, 0893700110) and secured with a clamping batten, if necessary.

  • Take care not to damage the membrane during installation.

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


Installation instructions for over-rafter insulation


  • WÜTOP Thermo Vario SD is ideal for use as a vapour retarder for over-rafter insulation.

  • Installation: Same procedure as for between-rafter insulation.

  • Please keep in mind: Exposure to weather for max. 3 months.


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 Thermo Vario SD 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, art. no. 0992700050).

  • Recommendations: Secure WÜTOP Thermo Vario SD to the rafters using clamping battens.

  • Bond joints at the eaves (eave beams/masonry) using WÜTOP film adhesive (art. no. 08937001). Additional mechanical fixing with clamping battens is recommended.
