S-Vap HD SA

Self-adhesive Vapour Control Layer & Carrier Membrane

S-Vap® HD SA is an elastomeric self-adhesive vapour control layer and carrier membrane made of polymer modified bitumen with an aluminium composite and glass combination inlay.  The top suface has a sanded finish. 

  • Ease and speed of installation, due to self-adhesive property of backing.
  • Can be used in a totally adhered roof build-up. No additional fasteners required for securing the thermal insulation boards to the structural deck.
  • Can be used as 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 and carrier can withstand high wind loads; design load up to 3.2 kN/m2.
  • High adhesion/bonding strength leading to an air tight 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.
  • Wide application range, in regard to use in different system applications and/or in combination with different structural deck types, substrates.
  • Improved fire resistance achieved by added flame-retardant.

Can be bonded on roof slopes and up vertical abutments.

Usage

As a VCL, S-Vap® HD SA can be applied over most common substrates such as concrete, metal decks, plywood, timber boards and/or oriented strand fibre board (OSB) deck. As a carrier membrane, S-Vap® HD SA can be applied over primed Decotherm insulation. 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 uplift design
Temporary waterproofing layer: S-Vap® HD SA can also be used as temporary waterproofing layer, as top layer can be left exposed for up to 4 weeks. Important: If used in an adhered roof build-up, as a VCL or carrier, additional installation requirements must be applied e.g. use of Primer 610/600 to achieve full self adhesion strength:
  • Self adhesion strength on metal decks, in combination with Primer 610/600 max. design load of 3.2kN/m2
  • Self-adhered on concrete deck in combination with Primer 610/600 max. design load 3.2kN/m2.
Self-adhered on plywood/OSB deck in combination with Primer 610/600 max. design load 3.2kN/m2.

Application steps

SUBSTRATE QUALITY

Before beginning to adhere the S-Vap HD SA®, the substrate must be checked (clean without any surface contamination, free of foreign objects and or surface toppings, oil and grease free, and dry).

APPLICATION

Fixing Method – VCL:
S-Vap® HD SA is adhered to the substrate.  In case of a concrete, metallic or plywood/OSB substrate Primer 610/600 must be applied as substrate treatment, to achieve the required adhesion strength.

Concrete deck:
In plane concrete deck and or/levelled screed. Substrate shall fulfil general requirements and shall not contain any pointy and/or coarse-grained surface areas.

Primer 600/610 must be used in any case, at specified coverage, depending on surface smoothness and porosity, if used in an adhered system.

Plywood/OSB deck:
Substrate shall be clean, dry and primed first at the specified coverage rates, if used in an adhered system.

Corrugated metal deck:
Corrugated metal deck shall be clean, dry and free of oil, dust and grease. No primer is required.

Vertical areas / upstands and flashing
Flashings and terminations form the edges of the vapour control function and airtightlayer; thus these must be executed with care (until top edge of the insulation boards).

Fixing Method - Carrier:

Decotherm® Insulation shall be properly installed, smooth, without steps at joints,
clean, dry and free of oil, dust and grease. The boards must be primed with Primer 600/610 at the specified coverage rates and fully dried before application of S-Vap HD SA as the carrier.

When adhering S-Vap HD SA to itself, on an end-lap, or when terminating onto the sanded surface, a coat of primer 600/610 should be applied to that area of the sanded surface.  The adhesive lap edge, provided on the top-side of the membrane, should always be completely covered by the next layer of lapping membrane.
