Series 80 Heavy Duty Horizontal Sliding 4 Pane

Heavy duty horizontal sliding (HS) secondary glazing, available in two and three pane configurations. Suitable for treating patio doors, very large windows, secure receptions and recording studio doors.

The sashes slide with in the frames, so do not interfere with blinds or curtains. Large ribbon windows can be accommodated by linking units with a colour-matched mullion/ transom section. The sashes are removable which facilitates cleaning and maintenance.

Thicker glass specifications will provide higher levels of noise insulation. High levels of security can be achieved when using secure lock options and polycarbonate glass.

Will reduce heat loss by up to 50% using standard glass and up to 65% with a thermally efficient glass (low emissivity). High performance brush seals will almost eliminate drafts and ensure greater comfort near the window.


  • Acoustic: Tested in accordance with BS EN ISO 140-3: 1995 for acoustic performance: between 40 and 49 dB can be achieved.
  • Thermal: U-values as low as 1.81 W/m²K (timber primary window and low-E glass in secondary glazing).


  • Secured by Design (SBD) Accredited.
  • ISO 16933 EXV 33 (horizontal sliding two/ three pane only).
