Sarnavap®-2000 E
Sarnavap®-2000 E is an unsupported vapour control layer based on PE-LD/PE-HD (Low Density Polyethylen/High Density Polyethylen).
- Ease and speed of installation.
- Stays flexible at low temperatures.
- Long life-span.
- Non-decaying.
- Constant vapour diffusion resistance.
- High water vapour resistance makes it suitable in combination with all membranes.
- Wide application range, in regard to use in different system applications and/or in combination with different structural deck types, substrates.
- Recyclable
Usage
- Vapour control layer (VCL) is applied over most common substrates. Substrates should be smooth, dry and strong enough to support foot traffic.
- Sarnavap®-2000 E vapour control layer is used for flat and nominal pitch roofs.
- Sarnavap®-2000 E vapour control layer is not suitable for temporary waterproofing.

Application
Ambient Air Temperature
Ambient temperature: -20 °C min. / +60 °C max.
Substrate Temperature
Substrate temperature: -30 °C min. / +60 °C max.
SUBSTRATE QUALITY
Substrates should be smooth, dry and strong enough to support foot traffic.
SUBSTRATE PREPARATION
If the substrate surfaces is rough (e.g. raw concrete or sloped topping), install a levelling layer beneath Sarnavap®-2000 E.
APPLICATION
- Unroll the Sarnavap®-2000 E over the structural deck and temporarily weight in position.
- Unroll the next roll of Sarnavap®-2000 E positioning so as to ensure a minimum 80 mm overlap.
- Fold back the top sheet of Sarnavap®-2000 E and apply Sarnavap® Tape F (jointing tape) to the bottom sheet.
- Peel off release tape and carefully fold back the top sheet of Sarnavap®-2000 E ensuring no wrinkles or creases are formed.
- Apply pressure to the top sheet of Sarnavap®-2000 E with a welding roller ensuring good adhesion to the Sarnavap® Tape F. On metal decks the lap should be fully supported in order to apply the correct bonding pressure.
- At transverse joints an airtight bond is achieved by trimming the edge of the upper sheet at 45°.
- At perimeters and penetrations seal the Sarnavap®-2000 E by turning up and sealing to a suitable smooth surfaced abutment with Sarnavap® Tape F (jointing tape). For sealing flashing airtight.
Installation works shall be performed only by Sika Sarnafil Registered Roofing Contractors.
Installation of some ancillary products, e.g. contact tapes and Primer is limited to temperatures above +5 °C. Please refer to the respective Product Data Sheets.
Special measures may be compulsory for installation below +5 °C ambient temperature due to safety requirements in accordance with national regulations.
Note:
Sarnavap®-2000 E is not suitable as temporary or permanent waterproofing. It is not designed as roofing membrane and therefore can not replace the waterproofing membrane.
