Double Glazing Glass Safety

Postby Rippley » Fri Jul 25, 2008 1:15 pm

We have double glazing in all the windows and kitchen door panel (all around 2 years old) and all the glass on the inside is Toughened glass as it has the kite mark with BS6206/A but none of the glass on the external side of the glazing units is marked with any identification. Is this right?

The kitchen door glazed panel is in the 'at risk' area re safty regulations along with possibly 2 windows by 10cm and another window by 30cm (in relation to any glazing starting below 80cm if measured from the floor).

If this glass is for safety and for security (or so our landlord tells us as we're in a lower-ground floor flat) then what's the point of having Toughened glass on the inside and ordinary glass on the outside? We don't believe anything our landlord says so if he said the outer glass is Laminated- how can I check as it has no markings (eg BS6206) and I thought that if it's to be used as safety glass then it needs to be marked with the BS standard?
Any ideas please.....

Sorry- forgot to thank welsh brickie and allan the locksmith for your replies :!:

glass in doors should be fitted with safty glass and should be samped with the approved kitemark.
Double glazing units are usually just stamped on one side though.If you tap the glass with a coin it should sound exactly the same.If its laminated it will be a lower sounding tone than toughened.There is a device that is used to tell whether the glass is toughened or not but i have forgotten what its called.Hope this helps

Toughened offers no security and actually makes it easier to enter.Laminated offers much better security so maybe this landlord has got it right ?

Toughened is only there to prevent shards of glass falling on you should you fall through the pane.It will collapse into loads of tiny pieces a bit like a side window on a car does.the laminate will break like the windscreen on a car does.
