Application

Suitable for commercial, public, heritage, listed building, historic, museums, galleries, offices, universities, residential, schools, colleges, atriums and domestic buildings.

Features and benefits:

  • System incorporates a ventilated internal box-rafter design to minimize the risk of condensation.
  • Continuous pressure plates and snap on covers provide invisible fixings and a low profile appearance.
  • An optional period-style aluminium box-rafter and capping is available for heritage buildings.
