How can I tell if I have laminated glass?

2013yearofthehouse

I've had a door installed with supposedly laminated glass. The second door due to be installed at the same time has had to go back to the manufacturer as they used plain glass instead of the obscure we wanted. Since this is visually obviously, but the laminate isn't I thought I'd better check whether the installed one really is laminated, in case it's wrong as well.

The outer pane is obscure glass, stamped BS EN 12150 class 1, which I believe means it's toughened glass? The inner pane just has "REDITUFF" stamped on it. Is that just the manufacturers name? How can I tell if it's laminated glass please? (Other than breaking it! )

""Some glazing locations require the glass used to be a safety glass, these areas are called 'critical locations'. Safety glass is any glass complying with BS EN 12150 Class 1 such as toughened glass or laminated glass 6.4mm and thicker.""

According to that, it could be either - why do think it may not be laminated?
"BS EN 12150 class 1" confirms it is safe for that location.

Thanks for your reply. I assume it is laminated as that's what was ordered, but since the door manufacturers seem to be in the habit of getting things wrong (not just the other doors glass but the colour of the furniture also) I though it might be best to check. I don't mind either way (laminated or toughened) as, like you said, it's safe for the location, but the laminate glass is costing me more, so if I don't have it, I don't want to pay the extra for it.

The "BS EN" stamp is only on the outer pane, which is obscure glass with a patterned texture so I assume this is just toughened and wouldn't usually be laminated? and that only the inner pane is laminated, but like I said it only has the manufacturers stamp so I'm not sure.

Ignore this. Tried to edit the above, but lost Internet connection half way through and when it returned it had registered as a new post rather than an edit.

toughened has to be cut to size before treatment, lam can be cut by any glazier.

If your glass has a manufacturers mark on it I'd be thinking it's toughened, with lam if you look carefully you'll be able to see a sort of double reflection at the joint between the glass and the plastic

I think there's a sort of double reflection, no idea if I'm interpreting that right though! I've tried, probably unsuccessfully to capture it in a photo. http://www.flickr.com/photos/94712956@N05/8625111065/
