Home > Companies > Selectaglaze Ltd > Series 41 Lift Out

Heavy-duty lift-out (LO) secondary glazing unit suitable for treating large or curved windows which are rarely opened but need occasional access. Supports thicker glass for higher noise insulation.

Lift-outs can be used in combination with other window styles as side lights, over lights or fitted to large rectangular windows behind bulkheads. Rectangular frames may be linked with a colour matched aluminium transom/ mullion section. Release of the catches allows the panel to be removed for occasional cleaning and maintenance.

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


  • Blast tested to ISO 16933 Classification code EXV 33.
  • Secured by Design accredited.
