Argon Gas
Argon gas filled units as standard
Instead of air in between the panes of glass, all of our energy efficient windows are filled with an inert gas reducing heat loss even further.
Argon is a colourless, odourless, non-flammable, non-reactive, inert gas. Argon gas fills are used to reduce heat loss in sealed units by slowing down convection inside the air space. Argon gas is extremely cost-efficient, and works well with Low-e coated glazing.
As air itself is a good insulator, filling the gap between the glass panes with a low-conductivity gas such as argon improves window performance by reducing conductive and convective heat transfers. This phenomenon results from the fact that the density of the gas is greater than the density of the air. Argon is the most commonly used fill gas, due to its excellent thermal performance and cost-efficiency in comparison to other gas fills. Argon filling can lower the U value by up to 0.2 m2K (The lower the better). Don't forget, Argon gas filling is standard on all our windows.
Swisspacer Technology
Ordinary double glazed sealed units are composed of two pieces of glass and a hollow aluminum spacer around the edge of the piece of insulating glass. The hollow spacer has silica poured into it to act as a moisture-removing agent from the spacer between the pieces of glass. The problem with aluminum spacers is that aluminum is an excellent thermal transfer agent, which means that it permits the outside cold temperatures to reach the inside of the insulating glass unit. To prevent thermal loss caused by conventional aluminum spacers in insulating glass units, more and more consumers are demanding low-conductivity materials to separate panes of glass. The answer to this problem is a 'warm edge' spacer which is less conductive and outperforms pure aluminum. The heat transmission coefficient is at least 0.1 W/m2K lower than that of conventional aluminium spacer bars. Reductions of up to 0.3 W/m2K can even be attained. The result: the high tech spacer bar SGG SWISSPACER V enables heating costs to be reduced by up to 5%. That’s easy on the wallet, and with reduced CO2 emissions, also on the environment. All of our energy efficient windows have one black swisspacer which is situated between the inner and middle pane as standard. Other colours are available.
