Application

For openings in cavity walls.

Description

One-hour fire-rated, fully insulated cavity closer system. Creates a continuous ring of fire protection around openings in cavity walls, combing cavity closer and cavity fire barrier in one product. They feature foil-encased fire insulation that reflects flames and heat and prevents moisture penetration.


Features and benefits:

  • Superior thermal performance to other traditional methods of closing cavities, such as battens in timber frame or returned brickwork.
  • Provides a thermal break which stops cold bridging.
  • Complies with current Accredited Construction Details (ACDs) and E&W Approved Documents B and L.
  • Tested to BS EN 1363 as demanded by building regulations.
  • Provides a damp proof course around the opening.
  • Zerto Global Warming Potential (GWP) and Ozone Depleting Potential (ODP).
