Application

The VCL has a wide application range, in regard to use in different system applications and/ or in combination with different structural deck types and substrates. Can be applied over most common substrates such as concrete, metal decks, plywood, timber boards and/ or oriented strand fibre board (OSB) deck.

Description

An elastomeric self-adhesive vapour control layer (VCL) constructed from polymer modified bitumen with an aluminium composite and glass combination inlay. The top surface has a sanded finish.

Features and benefits:

  • 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 are required for securing the thermal insulation boards to the structural deck.
  • Can be used as temporary waterproof layer for up to four 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; and has a design load up to 2.4 kN/m².
  • 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.
  • High water vapour resistance makes it suitable in combination with all membranes.
  • Improved fire resistance, which is achieved by added flame-retardant.
  • Can be bonded on roof slopes and up vertical abutments.
  • CE marked to BS EN 13970 and manufactured in accordance with BS EN ISO 9001.
