Specifications - Double Glazing Glass Sealed Units & Manufacturing Process - Insulated Glass Units

Our insulating glass units are manufactured as follows:

  • two (double glazed) or three (triple glazed) glass panes
  • separated by desiccant filled (moisture absorbing) spacer bars
  • Double Hermetically Sealed in our humidity controlled factory area, with dry air in the unit cavity:
    • First Impermeable Seal - the spacer bars are side-sealed, all round, both sides, to the glass
    • Second Impermeable Seal - the perimeter of the sealed unit is filled
  • if specified, the air is then flushed out and replaced with an inert gas to improve thermal and/or acoustic performance

All sealed units are manufactured in strict accordance with BS EN 1279 - Part 1 (Description, Properties & Performance) & Part 2 (Air Filled Units) or Part 3 (Gas Filled Units)

Fitting - Replacement Double Glazed Units

To maintain the integrity of sealed insulated glass units and prevent the chance of future damage, breakage or seals breaking down, it is important that they are correctly refitted. Mostly this is a fairly simple common sense process and, just like the measuring process, if you are at all unsure of anything, then we will happily talk you through it. Like everything else these days, you can find all the information and videos online. Our top tips:

  • before fitting the new unit, clean the exposed framework & ensure that the drainage holes & channels are unblocked
  • always remember to sit the new unit back on the original plastic setting blocks - if there weren’t any, then that will be why the original unit failed - tell us & we will give you some
  • opening window sections & doors will have some corner &/or side setting block packers - these are positioned (in a process called “toe & heeling”) to ensure the correct opening operation - when exposing & removing the old unit, note their positions & replace them when fitting the new unit

As long as you follow the above steps, your new double glazing glass units will stay mist and fog free and in great condition for many years beyond the guarantee period.

If you are reasonably “handy,” you won’t have any problems.

We provide Setting Blocks and Packers for all Depths of Insulating Glass Units, London Glass Works

The Weight of Glass Units

Glass is heavy, double glazed glass is twice as heavy!

  • window units are usually 2 x 4 mm glass - which will weigh approx. 4 lbs/ft2 or 20 kilos/M2
  • door units are usually 2 x 6 mm glass - which will weigh approx. 6 lbs/ft2 or 30 kilos/M2
  • triple glazed units will be half as heavy again as the above

If you do not feel confident to handle the weight of large units, especially large 6 mm door units, then we recommend that you use our fitting service.
