Insulated Glass Unit
SSG® DuraComfort is an insulated glass unit formed by sealing non-convective space in between two or more plies of glass. The pieces of glass are separated by a spacer around the perimeters which is filled with desiccant to absorb moisture. The spacer (available in mill or coloured finish) will be sealed by a sealant, giving rise to a hermetically sealed space between the pieces of glass.
The primary sealant of polyisobutylene provides maximum protection against moisture vapour transmittance as well as minimises thermal edge conductance between the spacer and the glass, hence saving energy. SSG® DuraComfort offers different secondary sealants for versatility in product application, as well as maximum strength and protection from stress and extreme temperatures.
SSG® DuraComfort can be used for buildings with exceptional high heating or cooling requirements; places that require temperature and humidity to be strictly controlled; environments that need regulated atmosphere and prevention of condensation as well as areas which require sound insulation.
SSG® DuraComfort Triple Glazing Unit (TGU) is made up of three panes of glass separated by 2 spacer units with the flexibility of utilizing one or two panes of SSG® Low Emissivity glass for optimum performance results, to provide maximum energy savings and improved thermal comfort.
SSG® DuraComfort TGU insulates up to 40% better than a Low Emissivity double glazing unit of the same source, provides approximately 60% less transmitted heat for better thermal comfort, and offers better condensation protection and acoustic performance for the external glass façade.
Note: In summer conditions, Low E and reflective coatings display best performance on surface #2 of outdoor glass in terms of shading coefficient (SC) and U-Value.
Note: U-Value is based on American Society of Heating, Refrigerating and Air Conditioning Engineers’ standards.

SSG® DuraComfort can be formed using a range of Design glass such as Ceramic Frit glass, Digital Print glass and Low Iron glass.
When used with heat-absorbing glass, heat reflective glass and SSG® Low Emissivity Glass in our Eco range, SSG® DuraComfort will enhance heat insulation and further reduce the load on the cooling and heating system.
Other custom combinations are also available upon request.
The enclosed layer of inert gas amplifies the insulation capability of SSG® DuraComfort, hence preventing cold or warm draughts and providing a pleasant internal environment all day round. An increase in cavity space results in an increase in sound insulation properties.
Prevention of Dew Condensation
For monolithic glass, the temperature difference between the outside and inside of a room will often lead to condensation. With SSG® DuraComfort, the insulating effect of the inter-pane inert gas layer makes it difficult for the glass to become cold and consequently harder for dew condensation.
With the inter-pane layer of inert gas, transmission of sounds is reduced, saving efforts to reduce noise pollution with other means. The amount of sound reduction depends on the configuration of the insulated glass.
SSG® DuraComfort allows for configuration flexibility with varying thickness and glass types to match the requirements of individual glass structures.
