Application

  • Floor/ wall connections.
  • Wall/ ceiling connections.
  • Window/ wall connections.
  • Pipe penetrations.
  • Walls.
  • Wall/ wall connections.
  • Vertical and horizontal joints.
  • Curtain walls.
  • Wall/ roof connections (steel deck).


  • Envelope Penetrations – Service penetrations can be the downfall of any air tightness testing. The Passive Purple home pack is applied around objects that penetrate any surface to the external envelope, sealing where most tapes and membranes fail. Before you apply Passive Purple, first apply polyurethane foam around any penetrations. After hardening, remove the excess foam and apply a generous amount of Passive Purple with a flat paintbrush. In all cases, apply a sufficient, well-covering layer to guarantee airtightness.
  • Window/Door Reveals – Passive Purple can be applied (and is tested) on different construction materials such as concrete, brick, wood, PVC, aluminium and polyurethane foam. With a coat of Passive Purple, the whole window/door reveal can be made airtight.
  • Awkward Joist Zones – Areas like joist zones play a major roll in air leakage as over time and with building settlement, cracks and substrate changes/shrinkage occur resulting in hidden air leaks. Passive Purple Brush has 45% elongation/elasticity which bonds too and stretch’s/moves with the substrate without decreasing in performance, resulting in a firm and still completely airtight high performing detail.
  • Window Formers – Passive Purple Brush is easily applied with a paintbrush to get at any hard to reach, awkward spots where traditional tapes and membranes fail. Unlike many traditional methods of sealing these areas, Passive Purple Brush can adhere to multiple substrate changes like blockwork, plastic and metalwork and does not shrink, deteriorate or come unstuck over time, Also.. its liquid putty state makes it easy to brush into and around all gaps and cracks effortlessly

Description

A full BBA-certified polymer-based paste which is applied with a paintbrush and dries to an airtight vapour control membrane (AVCM) with good adhesion on different substrates.


BBA Certified, brush-applied Vapour Control Membrane for Connections and Service Penetrations. Use on multiple surfaces.


For small projects, such as private houses, the Passive Purple Home Pack can be used with a flat paintbrush. In this case, an airless spray device is not needed.


The wall/ceiling connections also need to be made airtight, especially when the connections are made of two different types of construction materials such as red brick/concrete or steel/concrete.


Different construction materials react differently to changes in humidity and temperature, moving at different rates, which can lead to small cracks in plaster or another type of finishing. That movement can create air leaks that cause your building’s energy performance to suffer and potentially open the gateway for damp and mould to appear.


Features and benefits:

  • The product is ready to use and can be applied both vertically and horizontally.
  • Volatile organic content (VOC) free.
  • British Board of Agrément (BBA) and PASSIVHAUS certified.
  • A Passivhaus certified score of 0.03 ACH which is 20x lower than the required 0.6 air changes per hour (ACH).
  • Can guarantee a score of 0.6 ACH.
  • A single installer can apply up to 300 m² of Passive Purple a day using an airless spray device. Construction is sped up, and labour costs are dramatically reduced with this easy airtight pain.
  • M1 class.
  • Windows and door reveals are a common culprit for allowing significant air leakage. With its fibre reinforced make-up, Passive Purple Brush will completely seal and dry into a tough airtight membrane that will not peel or become unstuck like your classic silicones and tapes
  • Bridge the larger gaps in the wall connections and joints for a tough yet flexible seal which allows itself to work with building settlement before spraying over with Passive Purple Spray
  • Completely seal the wall to ceiling connections with a perimeter application of Passive Purple Brush or Spray
  • Completely seal the slabs to panels and walls with a perimeter application of Passive Purple Brush or Spray
  • Service penetrations can be the downfall of any building. Passive Purple and Passive Purple Brush are applied around objects that penetrate any surface of the external envelope sealing where most tapes and membranes fail and are too awkward to apply
  • Cost effective and can be applied with great speed and on damp surfaces.
  • Service penetrations can be the downfall of any air tightness testing. The Passive Purple home pack is applied around objects that penetrate any surface to the external envelope, sealing where most tapes and membranes fail. Before you apply Passive Purple, first apply polyurethane foam around any penetrations. After hardening, remove the excess foam and apply a generous amount of Passive Purple with a flat paintbrush.
