Secondary Glazing;
Slim-line Equal Leg System

Secondary Glazing, Economy Odd Leg System, Face Fix

Our Slim-line Equal Leg system is our slimmest secondary glazing system, and unlike our Luxury Subframe System it has no need for a wooden subframe. This system includes a special high performance insulating foam for improved acoustic and thermal properties, which not only reduces draughts and noise - but actually makes this new system even easier and quicker to fit.

The outerframe has either a counter sunk fixing grove for hiding the screws when face fixed or a flange or lip that sticks out the back for reveal fixing. It is an all aluminium even leg system and is supplied with cover trims to hide fixing holes and provide a nice clean finish. Due to its aesthetically pleasing finish this system is highly suitable for domestic applications.


This product is new to Duration Windows. Therefore, there will be more information and pictures to follow shortly. For more information contact our sales dept.

  • Available in any of over 200 different RAL colours.
  • Face fix frames are pre-drilled as standard, reveal fix frames are only pre-drilled upon request.
  • A slim-line all aluminium system that can be face fixed or reveal fixed and is easy to install.
  • Supplied with cover trims in a selection of shapes and sizes for concealing the subframe and fixing screws.
  • Variety of glass types available to tailor our secondary glazing to your individual requirements; be it heat, noise or security that is your priority.
  • Highly suited for domestic applications due to its clean finish and concealed fixings.
  • Optional foam insert can be pre-applied to the outerframe, which will further increase the insulation & acoustic performance.
  • Available as two track horizontal sliders, tilt back vertical sliders, and soon to be available as lift out units. (see table below)


If the style of secondary glazing that you require is not available in this system please see our Economy Odd Leg system, Luxury Subframe system and Heavy Duty system.
