Sarnavap®-1000 E
Sarnavap®-1000 E is an unsupported vapour control layer based on PE-LD (Low 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®-1000 E vapour control layer is used for flat and nominal pitch roofs.
- 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®-1000 E.
APPLICATION
- Unroll the Sarnavap®-1000 E over the structural deck and temporarily weight in position.
- Unroll the next roll of Sarnavap®-1000 E positioning so as to ensure a minimum 80 mm overlap.
- Fold back the top sheet of Sarnavap®-1000 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®-1000 E ensuring no wrinkles or creases are formed.
- Apply pressure to the top sheet of Sarnavap®-1000 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°.
Installation works shall be performed only by Registered Sika Sarnafil 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®-1000 E is not suitable as temporary or permanent waterproofing. It is not designed as roofing membrane and therefore can not replace the waterproofing membrane.
