Double Glazed Window Pane Thickness

How thick are the two glass panes of a double glazing unit.

Double glazed window pane thickness. Most units are produced with the same thickness of glass used on both panes. Single pane glass of 3 16 thickness are good and 1 4 thickness are very good. Double glazing has 2 panes of glass or a pane of glass and another clear sheet spaced apart by a gap containing air or argon gas which is a better insulator than air. Estimating heat loss from double glazed windows.

What to look for amount of space between panes. Double pane glasses can reduce noise up to 25 percent and so are recommended. Thickness 14mm to 28mm. So the total double glazing thickness in millimetres mm encompasses the thickness of each pane of glass and the thickness of the gap in between.

Secondary glazing creates an air gap by inserting a second pane of glass or other clear sheet behind an existing windowpane. A typical glass pane is 4mm thick. A difference in glass thickness between the inner and outer panes will improve sound reduction even further. Toughened as standard.

So you pick a window glass pane of this thickness. A unit comprising of two 4mm pieces of glass weighs 20kg m2 a unit comprising of two 6mm pieces of glass weighs 30kg m2 a unit comprising of one 4mm and one 10mm pieces of glass weighs 35kg m2 a triple glazed unit comprising of three 4mm pieces of glass weighs 30kg m2 a sealed unit measuring 400mm x 1100mm in 4mm glass weighs 8 80kg a sealed unit measuring 1200mm x 1300mm in 4mm glass weighs. Fitting double glazed or secondary glazed windows. There are two ways of establishing the thickness of the overall pane no 1 is very expensive and can be only justified if you are going to replace a substantial number of them.

The insulating efficiency and the acoustic insulation are all greatly dependant on the gap or spacer thickness. Order double glazed units for doors windows. Double glazed windows are considered a safer option when compared to standard single pane windows. The more sun the shorter lifespan of the unit.

If you want good soundproofing then consider double pane windows. Given the thermal properties of the sash frame and sill and the dimensions of the glazing and thermal properties of the glass the heat transfer rate for a given window and set of conditions can be calculated. The ideal thickness for maximum efficiency is around 16mm for the space. Both the added thermal resistance you get from two panes of glass instead of one and the insulation effect of the airspace which slows down the movement of thermal energy thus reducing heat loss are what create the benefits of double.

This is then sealed to. However for some reason if you can t replace the windows then changing the old single pane glass with a thicker one can help. Thickness of double glazed unit the supplier of the double glazing panes also need to know the overall thickness of the double glazed unit please see diagram 1. Two sheets of glass are a lot harder to break than one and for even greater security you can specify toughened or laminated glass.

Maximum size 2500mm x 1000mm. The lifespan of a typical double glazed window is between 10 25 years although this depends on how much direct sunlight the window receives. Choose from glass types spacerbar colour gas filling options.
