Sika S-Vap 5000E SA

Self-adhesive Vapour Control Layer

S-Vap 5000E SA is a multi-layer self-adhesive vapour control layer made of polymer modified bitumen with a glass-fibre mat reinforcement and an aluminium foil as top layer.

Typical Uses

Vapour control layer (VCL) is applied over most common substrates such as concrete, metal decks, plywood, timber boards and/or oriented strand fibreboard (OSB) deck.

Special application within adhered systems:

• Adhered system: Self-adhesion strength limits max wind uplift design load
• Combined adhered system: Self-adhesion strength is part of wind-up lift design
• Temporary waterproofing layer: S-Vap 5000E SA can also be used as a temporary waterproofing layer, as top layer, can be left exposed for up to 4 weeks.

*Important: If used in an adhered roof build-up, additional installation requirements must be applied e.g. use of Primer 600 to achieve full self-adhesion strength:

• Self-adhesion strength on metal decks, in combination with Primer 600, max.
  design load of 2.4 kN/m2
• Self-adhered on concrete deck in combination with Primer 600, max. design load 2.4 kN/m2
• Self-adhered on plywood/OSB deck in combination with Primer 600, max. design load 2.4 kN/m2

Typical Benefits

• Ease and speed of installation, due to self-adhesive property of back layer and its specific weight.
• Can be used in a totally adhered roof build-up. No additional fasteners are required for securing the thermal insulation boards to the structural deck.
• Can be used as a temporary waterproof layer for up to 4 weeks, as a top layer without the need for additional weight/ballast and/or mechanical fastening.
• Due to its high adhesion strength, the VCL can withstand high wind loads; design load 2.4 kN/m2
• High adhesion/bonding strength leading to an airtight roof construction
• High tearing resistance under foot traffic makes it ideal for use on profiled metal decks
• High water vapour resistance makes it suitable in combination with all membranes
• For roofs with many details and complex geometry even when accessibility is limited
• Can be bonded on roof slopes and up vertical abutments
