What does double glazed windows mean?
Written by William Howard — 0 Views
Double-glazing is a window consisting of two panes of glass separated by a layer of trapped argon gas. The layer of argon gas has 67% of thermal conductivity of air, making it a poor conductor of heat, thus keeping warm air trapped inside your home and helping improve energy efficiency.

Thereof, is double glazed windows worth it?
Energy efficient windows can be a great investment toward reducing your annual energy bills, particularly during peak times. Double glazing, especially when combined with energy efficient glass tailored to your climatic needs, can be the most efficient way of reducing U-value and optimising SHGC.
Subsequently, question is, how is double glazed glass made? Double glazed windows are closed units made using two pieces of glass which are separated by an air gap of at least 12mm. The gap is sealed, and acts as a break between the inside and outside pieces of glass. The air gap is filled with gas which increases the insulation between the glass pieces.
In this manner, how can you tell the difference between single and double glazing?
Method 1: Look at the inside edge of the window. If you see two panes of glass separated by a small spacer system, then it's a double glazed window. If you see one pane of glass and no spacing system, then it's single glazed. Method 2: Open the window and use your fingers to touch both sides of it in the same spot.
