Some technical aspects of Glazing explained.
U-Value
The U-value describes how well a building element conducts heat. The lower the value, the better an insulator a material is
Gas-Filled
Both noise reduction and thermal insulation can be greatly improved by filling the space between the glass panes with a low conductance gas like argon, Gasses also offer significantly better thermal resistance than air, resulting in greater insulation and improved energy efficiency.
Low-E Coating
Low-E glass features a special coating on the window pane that reduces heat transfer, preventing heat from entering a home in warm climates or from leaving a home in cooler climates. Windows that feature Low-E coatings are far more efficient at reducing heat loss than non-coated windows.
Warm Edge Spacer Bar
Warm Edge Technology refers to the edge construction of a glass unit, Warm edge spacer bar help maximise insulation and minimise energy loss, Standard glazed units constructed with aluminium spacer bars are highly inefficient and would have a greater thermal energy loss.
