Cowen uses the most innovative methods of glazing in the industry such as Super Spacer and Argon Gas units to cut heat loss through your windows, saving you energy and money.
Super Spacer is a radical new version of the conventional metal bars around the edge of doubler-glazed units. It contains no metal and so keeps in a lot more heat.
Argon Gas double glazing sealed units use Argon as an insulator, it is a colourless, odourless, non-flammable, non-reactive, inert gas. Argon gas fills reduce heat loss by slowing down convection inside the air space.
