Security horizontal sliding (HS) framing system available in two or three pane options. Provides high levels of blast mitigation and intruder resistance, with equivalence to strong bars and grilles.

The sashes slide within the frames, so do not interfere with blinds or curtains and provide access to the outer window. Large ribbon windows can be accommodated by linking units with a colour-matched mullion/ transom section. Sashes should be removed by a specialist when cleaning and maintenance is required.

Suitable for extreme security situations where thick laminated and polycarbonate glass is required.

Will reduce heat loss by up to 47% using standard glass compositions and up to 65% with a thermally efficient glass (low emissivity). High performance brush seals will almost eliminate drafts and ensure much greater comfort near the window.


  • Acoustic: Tested in accordance with BS EN ISO 140-3: 1995 for acoustic performance: between 41 and 48 dB can be achieved.
  • Thermal: U-values as low as 1.84 W/m²K (timber primary window and low-E glass in secondary glazing).


  • LPS 1175 SR1 and SR2.
  • ISO 16933 EXV 25.
