What to look for amount of space between panes.
Double glazed windows are considered a safer option when compared to standard single pane windows.
This would give you the best of both worlds as you would get a very secure external pane which would make it difficult for intruders to break through whilst having a cost effecting safety glass on the inside.
These two types approaches are not mutually exclusive.
Both laminated glass and toughened glass are commonly used in glazing to provide protection from and in cases of glass breaking.
In recognition of the breakage characteristics of toughened glass we strongly recommend the use of a laminated glass in single glazed or as the inner pane of a double glazed unit where it is necessary to minimise the risk of glass falling after breakage.
It s strong it s versatile and when it breaks a special plastic interlayer in your double glazed window holds the glass in place.
It is possible to combine both toughened and laminated glass in the same double glazed unit.

Laminated glass can be used in double glazed windows as you call them.
Glazing in critical locations should either.

The typical space between panes ranges from 6mm to 20mm.
Where glass and glazing products are supplied for domestic use such as conservatories garages double glazing porches they must comply with the general safety requirement of the general product safety regulations 1994 gpsr.
Laminated glass technically has the same strength as regular glass but has a plastic interlayer between two panes of 3mm thick glass holding them together.
The pvb plastic interlayer is a tough resin which will hold the shards in place should the glass break providing a safe double layered design.
