03 Jun A Guide to Double Glazing
Double Glazing refers to a technique of treating a building with a barrier against heat transfer by the building’s walls and ceiling. Insulated glass is made from two or more window panes connected by a tight vacuum or sealed gas to the outer surface of a building envelope to reduce heat transfer through a portion of that building envelope. The term was first used in the 1960s but double glazing had become a standard material for buildings in many countries by the end of the decade. The United Kingdom requires the use of double glazing in new homes built and rebuilt and in older homes that are re-built and a reputable Double Glazing Tewkesbury company such as Firmfix should be used for this.
Double glazing can be made from a variety of materials. Aluminum and UPVC windows are the most common types. Double glazing is often framed with timber frames or UPVC honeycomb panels, which also provide security. Most double glazing consists of four or five panes of glass, which are interconnected with aluminium frames to form a sealed unit. These frames are usually attached using a strong metal track.
The method of construction depends on the type of glass used and the amount of air space available between the two sheets of glass. Aluminium and UPVC windows will both require the assistance of a special air gap, or spacer bar. The air gap is a rubberized air passage cut into the inside of each sheet of glass so that air flow cannot pass through the glass while double glazing is being constructed. The spacer bar allows the opening of a window to be slightly larger than the actual size of the window opening to allow for ventilation through the glass.
