Insulated Glass Units

types

In modern construction there is a variety of challenges facing transparent wall partitions. Thanks to modern solutions double glazed glass can protect against the loss of heat, prevent over-heating, protect against noise and constitute a temporary form of protection against burglary.

A glazed unit consists of at least two panes of glass which create an internal cavity filled with air or other gas, separated and sealed around the perimeter using a multi-step combination process by means of a spacer bar, sealing compounds and water vapour adsorbents (desiccants).

Air tightness

of glazed units

One of the most significant evaluation criteria for glass units is air tightness in terms of moisture penetration and loss of the glass unit’s internal gas, which serves to increase the thermal or sound insulation properties.

The solutions currently employed by Glass Systems ensure the superior air tightness of glazed units with spacer bars curved or cut in corners.

Our Sealed Unit manufacturing process

All our sealed units are bespoke and are made to our customer’s specific order depending on the glass type, size and any decoration required.

Long gone are the days when our standard sealed unit was made with two pieces of 4mm clear float. In today’s energy conscious world and as a result of legislation change sealed units are now made with glass containing highly complex low emissivity coatings.

Also advances in the technology of glass have enabled more benefits to be gained from the sealed unit. Self cleaning and noise reduction (acoustic) options may now be demanded, combined with the more traditional options of obscurity, or solar reflection. It may be that decoration such as coloured film, lead or Georgian bar inserts are required. A large percentage of what we make contains all of the above in safety glass – laminated or toughened as opposed to normal annealed glass.

Whatever glass is ordered the two panes are washed in order to remove grease and fingerprints and are then set either side of a spacer bar. Historically the spacer bar was aluminum or steel, but the shift towards more energy efficient sealed units has seen an increase in warm edge spacer bars made of materials more thermally efficient than metal.

Our Tri-seal applicator automatically applies the Edgetech Tri-seal product during the production process on our automated production line. It allows for non interrupted production of IGUs with various spacer widths.
