Slimline lift out (LO) secondary glazing, using the Series 45 casement profile without the hinges. Suitable for treating large, curved or circular windows which are rarely opened but need occasional access.

Lift-outs can be used in combination with other window styles as side lights, over lights, or fitted to large rectangular windows behind bulkheads. All fixings are concealed within the frame, which may be linked to other frames with a colour-matched mullion/ transom section.

Will reduce heat loss by up to 50% using standard glass, up to 65% with a thermally efficient glass (low emissivity). High performance compression 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 41 and 48 dB.
  • Thermal: U-values as low as 1.78 W/m²K (timber primary window and low-E glass in secondary glazing).
