Product Description

Zedex CPT high-performance damp proof course (DPC) and cavity tray system by Visqueen is manufactured from co-polymer thermoplastic (CPT). This ensures that it has a high-performance value when it is installed in the building.

Visqueen Zedex CPT DPC is superior when it comes to durability. Not only is it tear-resistant, but flexible and compatible for use with Visqueen products including damp proofing, gas proofing and tanking protection systems for all your insulation requirements.

  • When installing Zedex DPC by Visqueen, ensure the product overlaps the Preformed Unit (also known as a cloak) by a minimum of 100mm. This is the lap being bonded using Zedex Damp Proof Course Jointing Tape by Visqueen. When fixing the damp proof course on surfaces, you must ensure the Preformed Unit is bonded before mechanically fixing it to the inner leaf. The taping/fixing system will be the same as the Zedex Damp Proof Course Cavity Tray. If using joint support boards, ensure you place the Visqueen Zedex DPC beneath supported laps. This ensures you follow industry recommendations and provide support for the initial formation of the bonded lap. This can also ensure the system has long-term integrity.
