Application

Can be applied over metal decks in combination with mechanically attached Sika single ply roofing membrane. Can also be used as a temporary waterproofing layer for up to four weeks, although a minimum roof slope of 2% (approximately 1.1°) is required.

Ancillary products also available include Sika Trocal L-100, Sarna Cleaner, Sarnafil T Prep and Primer 600/ 610.

Description

S‐Vap 4000 E SA FR is a multi‐layer self‐adhesive vapour barrier, made from a cross-laminated PE film with aluminium inlay and a hot melt adhesive on the reverse.

It is applied over metal decks in combination with mechanically attached Sika single ply roofing membrane only. The product can be used as a temporary waterproofing layer for up to four weeks. Minimum roof slope of 2% (~1.1°) is required.

Features and benefits:

  • Ease and speed of installation, due to self‐adhesive property and its specific low weight, and therefore increased roll length.
  • High adhesion/ bonding strength, leading to an airtight roof construction.
  • High tearing resistance under foot traffic makes it suitable for use on profiled metal decks.
  • Good slip resistance due to the ridged surface structure.
  • CE-marked to EN 13984.

Applications:

Can be applied over metal decks in combination with mechanically attached Sika single ply roofing membrane. Can also be used as a temporary waterproofing layer for up to four weeks, although a minimum roof slope of 2% (approximately 1.1°) is required.
