Key Features / Performance Characteristics

  • Series 852 sliding door is an innovative thermally broken aluminiun commercial door system designed to complement the Elevate™ Commercial thermally broken CentreGLAZE™ and FrontGLAZE™ framing systems.
  • Incorporating ThermalHEART™ technology, Series 852 sliding door delivers excellent thermal performance and is ideal for commercial and high-end residential applications where minimising heat or cold transfer is desired.
  • To ensure excellent thermal performance ise achieved, a "Thermal Break" is incorporated into this sliding door which separates the inside and outside elements of the frame providing an insulator to minimise the transfer of heat or cold between the elements.
  • This insulating strip in this sliding door is manufactured from polyamide and delivers the same structural properties as aluminium to ensure the integrity of the sliding door is maintained.

  • We also offer a range of snap-on glazing beads to allow us to fit thinner glass – down to 4mm thick.
  • The sliding door stiles have been designed to accept wide backset (34mm and 38mm) locks. The greater the backset the easier it is to access the key.
