Secondary Glazing;
Heavy Duty System

Secondary Glazing, Heavy Duty System, Direct Fix / Reveal Fix

Our heavy duty secondary glazing system is stronger and more robust than our other secondary glazing systems. The thicker frames enables it to take double glazed sealed units and achieve larger maximum sizes. Our heavy duty system is most commonly used in extreme circumstances, where single glazed secondary glazing is not sufficient enough to insulate and sound proof your windows.

Heavy duty secondary glazing is available as either a two track horizontal slider or a balanced vertical slider. The system is a direct fix system that is installed into the window reveal, away from your existing windows, helping to provide maximum sound and heat insulation. The system can however take single glazed units if required.


Technical Specifications

Maximum and minimum sizes differ depending on the style of secondary glazing that you choose. For details of maximum and minimum sizes you will have to look at the style of secondary glazing your require. (i.e. Horizontal Sliders)

Specifying - Suitable Applications
  • Suitable for both commercial and domestic applications.
  • Properties where the extreme external noise levels makes life unbearable - even where double glazing is already fitted.
  • For treating windows that need extreme heat loss reduction and / or draught reduction.
  • A property where you are unable to modify the existing external windows.
  • Leasehold properties, where changing the existing windows may be uneconomical.
  • Where the aesthetics and slimness of the secondary glazing is less of a concern than the level of noise and heat insulation.
  • Perhaps not as suitable for use in Listed Buildings as our other secondary glazing systems - the thicker frames are not quite as discreet and unobtrusive.

Please note: Glass specified must comply to the glass safety BS 6262: Part 4, 1994 regulations. (see document downloads)
