How our optional Energy Efficient Glass makes double glazing more effective
Our optional Energy Efficient Glass can make double glazing units even more effective than triple glazing and cuts fuel bills.
A special thermal and transparent coating which is usually applied to the inner pane of the double glazing unit, allows less heat to escape through your conservatory windows than ordinary glass – thanks to this microscopic energy saving coating, these double glazed units let the sun’s rays through, but reflect heat from fires and radiators back into your conservatory, heat which standard double glazing allows to escape.
In addition to this, the units are constructed with high insulating spacer bars for improved thermal performance and a reduction in internal condensation.
The energy efficiency of glass is measured by it’s U value.
The ‘U’ value of a double glazing window is the measure of its ability to transfer heat – so double glazing windows with the lowest U value are the most efficient insulators against heat loss from a room or conservatory.
How Energy Efficient Glass Works
Windows incorporating Energy Efficient Glass allow heat from the sun through, but reflect heat from fires and radiators back inside.
Energy Efficient Glass – more than double the thermal efficiency
|Double Glazing Unit Specification||U Value (W/m3K)|
|Standard Double Glazing Units||2.8|
|Energy Efficient Double Glazed Units||1.2|
The above values are based on 4mm glass thickness and are determined in accordance with the requirements of BS EN673: 1998 for ‘normal’ exposure conditions. U Values are rounded to the nearest 0.1 W/m3K.
