Home > Companies > Selectaglaze Ltd > Series 95 Vertical Sliding

High security vertical sliding (VS) secondary glazing, suitable for use where high levels of intruder resistance and blast mitigation are required. The framing section provides access to the primary windows for cleaning. The physical resistance is equivalent to high security bars or grilles. A minimum frame gap of 75 mm is recommended.

Multi point locks are incorporated and all fixings are concealed within the frame. Sashes slide within the frame so do not interfere with blinds or curtains. Twin brush seals included for high sealing efficiency.

Will reduce heat loss by up to 47% using standard glass compositions and up to 65% with a thermally efficient glass (low emissivity).


  • 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.
