The term leaded glass refers to all glass constructions held in place by lead, copper or zinc frames. Leaded glass is commonly used in windows, but also doors, fanlights, sidelights and other glazed features. It is generally used in buildings with an older architectural style, although some modern houses still suit the design.
One major problem with leaded glass in doors and windows is that it can break or weaken through the use of excessive force. You can double glaze these glasses by installing two panes of glasses with an air-gap in between. Instead of the air gap you can also use a layer of argon gas in between. This makes the window stronger and protects your house from strong winds, snow and hail. Double glazed windows also provide better insulation, which saves you energy and heating costs. These glasses also are very difficult to break and thus more secure against intruders. Double-glazing leads to reduced costs and longer the life of these glasses.
The disadvantages of glazing these glasses are that, sometimes faults develop in the glazed unit. The glass panes then begin to mist and condense. Heat can also build-up in the unit, which can result in the window expanding and contracting.
Glass in houses and other buildings have functional as well as architectural properties. The glasses in doors and windows are sources of light and ventilation as well as protection against bad weather, other environmental and human threats. They can offer varying degrees of light filtration and privacy. They also enhance the architectural beauty of any structure, be it a house or a church. All double glazed doors and windows can be embellished with leaded glass. Lead is applied to the glass in diamond, square, rectangular, Elizabethan and Tudor designs on the glass. Leaded strips of widths 6mm and 9mm are the most common.
In double-glazed sealed units, one of the two glasses are leaded, usually the outer one. The inner glass pane is left clear. This allows you to clean it easily. You can also add a leaded design to your existing window. This is known as single leading as you can apply the lead only on one side of the glass, the one that faces outside and not on the side facing toward the innards of the unit. When you buy an assembled double glazed sealed unit you can have double leading done, where the lead is applied to both sides of the outer glass. Where double leading is done, you should keep in mind that the leading done on the pane of the glass facing inside the sealed unit will not be affected by environmental pollutants and elements, and therefore will not change colour or age. This is unlike the leading done on the outside – this is vulnerable to corrosion due to air, water and other outside elements. You can solve this problem by using not new but special aged lead that is already exposed to such factors. This is more expensive but will give the windows a uniform look.
Double glazed glass windows are, in the long run, worth the expense and the trouble. However, you must take care of it meticulously and install it properly. Only then will you get valueyou’re your hard-earned money.
