Example glass markings
In the UK, by law, to determine what quality & type of glass is installed in a particular door or window all you have to do is quickly check the visible stamp mark displayed in one of the four corners of the glass.
The marking shown on this glass is pretty much what the majority of the population have installed in their windows and doors - glass accredited to 12150 standard.
I would be confident in guessing at this point this is what you have?
This is actually called Toughened glass ..... IT IS NOT TOUGH AT ALL WHEN HIT!
If you have the sequence markings of 14449, you have the correct security grading of glass - Great news!
If you have no markings anywhere on the glass I would be concerned as to the quality of the glass and the person who fitted it.
So now we have determined what glass you have installed or more importantly - haven’t got installed.
What are your options when it comes to enhancing this huge home security weakness?.....
