Additional information


The Wedge-Lok® fastener is a unique, plastic device that uses the principle of leverage to wedge between the masonry reinforcing or ties and cavity wall insulation. The wedge design and rib-faced locking system guarantees positive contact of insulation with the substrate.

The simplicity of the Wedge-Lok® means that:

  • No adhesives are required for insulation retention.
  • There’s no penetration of the air/vapor barrier.
  • Visual inspection can be made after installation.

These advantages add up to a practical, economical and permanent attachment of cavity wall insulation. Wedge-Lok® can be used in any cavity wall incorporating insulation and Blok-Lok® masonry reinforcing or ties.
