Application

For fixing to an existing inner leaf structural wall.

Only for installation by competent design/ installation contractors.

Please ensure to accommodate for deviations in the primary support structure.

Description

Fully drained and back-ventilated rainscreen facade system, with aluminium panels which are directly fixed onto the Matrix-T aluminium carrier system.

Features and benefits:

  • Allows ventilation and drainage to the cavity in line with standard rainscreen principles.
  • Provides an aesthetically pleasing external envelope solution.
  • Quick installation.
  • Can be adapted to suit specific project requirements.
  • Incorporates components such as insulation, membranes, and breakers.
  • Available in a range of configurations.
  • Perforations can be integrated into the panel, including uniform lines, patterns or pictures.
  • Fully tested and accredited to Centre for Window and Cladding Technology (CWCT) standards including ‘Standard for walls with ventilated rainscreen’ and ‘Standard for testing of ventilated rainscreen'.

PSP Architectural have passed the following tests which are required by the CWCT for rainscreen systems:

  • Wind resistance – serviceability.
  • Wind resistance – safety.
  • Water tightness – dynamic.
  • Water tightness – hose.
  • Impact resistance.

Consult manufacturer for further details.
