Any double glazed unit is made up from 3 major components;
Each individual component has its own set of unique characteristics and, combined, they provide a double-glazed unit that provides a variety of benefits to suit any individual’s needs.
Glass is the main component of any IGU. However, glass, in itself, is a poor insulator and heat can pass through it with ease. It is the air or argon spacer in a double glazed unit that gives it its thermal attributes.
Different combinations of glass can give other benefits too, including noise and UV reduction, solar control, privacy and security.
We are here to help you make the correct choice of glass, which will be specific to your needs.
The spacer bar forms the cavity between the two panes of glass.
Most glass manufacturers supply units with a metal spacer bar that is in direct contact with the glass. This acts as a conductor making the unit more susceptible to condensation.
Our units are manufactured with 100% polymer foam spacer bars, which provide greater thermal and acoustic properties, additional durability, energy efficiency and mould protection compared to its metal counterparts.
When air is completely sealed between two panes of glass the still air becomes a thermal barrier reducing heat loss by half when compared with a single pane of glass.
To further improve heat loss reduction the cavity is filled with Argon gas instead of air. Argon is denser than air and so provides greater resistance to air trying to pass through it.
