Glazing Types

Two styles of glazing are available to fit today. The first is the sealed glass unit and the second is called the secondary glazing unit that will add to and sit behind an existing windowpane. By its description it is quite obvious that that the send form is the easier to fit, but if you have some credible skills and a “can do” attitude then you could consider the first example also. London Glazing tradesmen can advise.

Secondary Glazing:

• The normal way to fit secondary glazing is to fit it to the frame of the window itself or to a timber framework inside the window frame.
• An ideal width between the original glass and the new glass is around 20mm, making the first option more efficient.
  There is no need for glass because clear plastic sheeting plastic film will work well. London Glaziers supply glass.
• Be careful when placing materials like plastic or glass in front of a window opening and not attached to the window casement, as it can prevent the window from opening.

Demountable Glass:
This type of glass is set in the window casement and secured to the existing window with clear tape or magnets. They will allow you to remove the secondary sheet of glass or plastic if you need to use the window. Or even to take it out in the warmer months.

Operable Glass:
This is a secondary glazing unit that can be fitted into sliding tracks and then attached to the window frame. There are cases where, the window may be hinged to allow it to open. The glass is edged with draught proof strips for added insulation when it is shut. The units are available in kits and are straightforward to fit.
