Double Glazed

Our double glazed units are a multi-glass combination consisting of two panes enclosing a hermetically-sealed air space filled with an inert gas, usually Argon. This type of Insulating Glass Unit (IGU) will reduce thermal losses, offers lower energy consumption and perfect transparency by reducing the incidence of condensation on the warm air side.

Our standard double glazed unit is as shown.

It conforms to the standardised European EN1279-5 certification with the following properties;

Thermal Properties - 1.1W/m2K

Radiation Properties:
Light Transmission - 79%
Reflection - 12%
Solar Energy Characteristics - 61%
