ᐅ Which type of glazing? Thickness, laminated safety glass (LSG), heat-reflective glass, toughened/tempered glass, and so on?

Dear homeowners,
We are currently working on the quotes for the windows. We are building a two-story house. Therefore, there are tilt-and-turn windows on the ground floor and first floor, as well as many floor-to-ceiling units on both levels. Additionally, we have planned a corner window on the first floor and a lift-and-slide door system on the ground floor.
All the quotes have come in with the following glass configuration:
8 mm (5/16 inch) laminated safety glass (LSG), 4 mm (5/32 inch) float glass, 8 mm (5/16 inch) laminated safety glass. For the corner window, the outer pane is specified as 8 mm (5/16 inch) toughened safety glass (TSG).
Now we are wondering if this might be overkill in some cases. 6 mm (1/4 inch) laminated safety glass should be sufficient at least for personal protection (falling through floor-to-ceiling units). Burglary resistance is a consideration on the ground floor, but for resistance class RC2, a special type of glass would be needed (at least for the outer pane).
How have you approached this topic? Do you use the same glass configuration throughout, or do you optimize it depending on the window’s position, size, etc.?
Thanks in advance for an interesting discussion!

The laminated safety glass (LSG) should always be installed on the side requiring protection (usually the interior) rather than the exposure side (usually the exterior). The main reason for this is that LSG positioned in this way provides the best protection against injury and splintering for the person, room, or object being protected.
If the pane is not installed but just standing next to it, that should have been a joke.
As long as it is properly installed, it doesn’t make a real difference. However, for a burglar and for the protected side, it does matter. Just take a look at tests with different types of glass for clarification.

Laminated safety glass (VSG) should always be installed on the protected side (usually inside) and not on the attack side (usually outside).In the case of a break-in on the ground floor, the attack comes from outside; in case of a fall against the glass on upper floors, the impact comes from inside. I haven’t looked into the legal aspect yet, but from a technical standpoint, laminated safety glass does not fulfill the requirements for fall protection.annab377 schrieb:
So it really doesn’t matter whether laminated glass is installed on the inside or outside regarding burglary protection,Above all, you should understand the “S” in “VSG” as safety relating to “protection against shards,” not as “protection against breaking in.” It stands for “laminated safety glass,” not “laminated burglar-resistant glass,” and it is by no means comparable—certainly not even at 8mm thickness—to the bulletproof glass used in banks and jewelry stores. If it increases your sense of security, the extra cost is definitely more about peace of mind than the material itself.I used to be an aluminum window manufacturer, where many customers were relatively affluent, yet laminated safety glass accounted for only a fraction of our sales. By the way, our mostly triple-glazed units typically used just 4mm (0.16 inch) thick glass panes. In my opinion, laminated safety glass is a premium item offered mostly to customers who might otherwise spend their money on homeopathic remedies.
