Door security - double or triple glazing?

Possom

If getting an external house door installed which would have a perimeter uPVC frame and be fully glazed with one pane of glass (so no strengthening horizontal/vertical uPVC bars), would the security of the door be improved to any great extent if it was tripled glazed as opposed to double glazed?

The rest of the house would have double-glazed windows.

Thanks.

I doubt it would make much difference; you'd just break each pane one at a time if you were trying to break in that way.

If the panes are the same thickness in the triple as double (which I think they generally are ) then I guess it will help a tiny bit, but as said it's only going to delay someone by an extra second, however it's still an extra pane to break and a bit more noise to make.

Double with the outer pane 6mm laminated would be my suggestion

Agree with SatanicHare.

Remember if the glass is below a level of 900mm it has to be safety glass. Normally peoplle use heat treated glass which shatters into thousands of tiny pieces if broken. Laminate satisfies the safety requirement, but will significantly aid security.

Do you mean the outer pane is two sheets of 6mm stuck together?

Or the outer pane is two sheets of 3mm to total 6mm?

The outer pane is 2 sheets of 3mm glass sandwiched around a plastic sheet. It totals 6.2mm. If it was two sheets of 6mm glass, you would need a Coles Crane to lift it!!

In a door its any glass below 1500mm from the floor phill, 800 in a window and any glass in a window thats within 300mm of a door needs to be tuff or laminated too.

I have mixed feelings with regards to laminated glass.Its fine for added security in doors but some people specify it in their windows but the problem I see is in the event of fire you will never break laminated glass to get out if the window won't open. I've replaced numerous windows that people have either lost the keys to the locking fasteners or the windows have swollen up and they won't open. At least with 4mm tuff glass you can break it.

The other option is 6mm tuff glass (same price as 6.4 laminted) which again is almost impossible to break ,even with a hammer. I recently had some units delivered that had scratches on so I rejected them and the supplier said just throw them in the skip.I tried to break them with a 22oz hammer and gave up in the end.

Happy to be corrected.

Were those wooden frames? I'd be getting uPVC.

If both options are the same price, and just as difficult to break, I suppose it's just down to preference? Unless there's anything else to differentiate them?

With the laminate glass, I wonder if there's the possibility of the two laminated panes 'rattling' due to vibrations?
