Have you ever seen a misted up double glazed unit that seems to suffer a from condensation within side two panes of glass. Many people ask themselves what is this happen this get back to the basics because sometimes is not always the fault of the glass it can sometimes be the responsibility of the installer.
So how is it made?u ask
Let’s start with the double glazed unit the double glazed unit generally comprises in three layers the first layer of glass is generally 4 mm thick this then sits on a spacer bar which can be anything from 12 mm to 20 mm inside the is placed a sand like substance which is called desiccant the desiccant is supposed to absorb any moisture that is built up in between the second pane of glass that traps it together this is how you get your double glazed unit;
Over a period of time due to the sun drying out the desiccant it then starts to slowly over a period of time stop working because of this the double glazed unit has no longer any facility to dry out the moisture that is then trapped between the two pieces of glass;
Glass and glazing manufacturers generally supply a five-year guarantee or in some circumstances with large or national companies they generally extended warranties up to the period of 10 years.
It is quite easy to replace the double glazed unit all you need generally is a thin scraper inserted to the line of the breed to the window sash gently ease out the window breed to expose the side of the unit once all the breeds are out the double glazed unit may be taken out and replaced with a new one we would estimate around the period of half an hour to replace the double glazed unit.
