Which panes? Thickness, laminated safety glass (VSG), polished glass (FL), tempered safety glass (ESG), etc.?

Dear clients,

We are currently working on the offers for the windows. We are now building two stories. Therefore, there are tilt-and-turn windows on the ground floor and upper floor, as well as many floor-to-ceiling elements on both floors. In addition, we have planned a corner window on the upper floor and a lift-and-slide system on the ground floor.

The offers have now all arrived with the following glass filling:

8 mm laminated safety glass (VSG), 4 mm float glass (FL), 8 mm laminated safety glass (VSG). For the corner window, the outer pane is designed as 8 mm tempered safety glass (ESG).

Now we are wondering whether this is partially overkill. 6 mm laminated safety glass (VSG) should at least be sufficient for the protection of persons (falling through floor-to-ceiling elements). Burglary protection plays a role in the considerations for the ground floor; for RC2 one would need a special glass again (at least for the outer pane).

How have you approached the topic? Uniform fillings everywhere, or optimized depending on the window (position, size, etc.)?

Thanks in advance for an interesting discussion!

The glass portion of the price is no joke. Of course, in the north, you can save on sun protection and the like.

6 mm laminated safety glass should at least be sufficient for the protection of people (falling in with floor-to-ceiling elements).

But you are not talking about balcony railings here, but about window glass. Why should a double-glazed unit be less than 8-4-8 thick just because one of the panes could fulfill its breakage safety thinner?

It's purely a price consideration. One of the window manufacturers made it seem as if we could (noticeably) save money by, for example, foregoing laminated safety glass where it's not necessary or going with 6mm...

But if the glass doesn't have a significant price effect, then I would also want to stick with 8-4-8...

For the RC2 relevant areas (ground floor), you need something special, right?

as if we could (noticeably) save if we, for example, do without laminated safety glass where it is not necessary or go down to 6mm...

Avoiding special features in the glass does save something. But I have not heard of 6 mm panes for the German market yet.

for the RC2 relevant areas (ground floor) you still need something special, right?

A burglary resistance class is not a matter of just individual parts.

A burglary resistance class is not something that applies to only individual parts.

Of course, I only meant the glass, it has to be P4A... the fittings alone would be RC2N...

I am currently using a window configurator. It offers VSG 6 mm on the inside or VSG 6 mm on the outside (both at the same price).

VSG is laminated safety glass, which is supposed to protect against injuries from glass breakage (less shards due to the film) but also against burglaries (because it resists penetration). Now I’m thinking that I’ll just choose the VSG 6 mm on the inside and kill two birds with one stone: 1) if someone falls against or through the glass from the inside, the film protects against major injuries and 2) it’s also more burglary-resistant because the VSG is on the window.

Or does it actually make a difference for burglary protection where the VSG is placed (inside or outside)?

have you gotten offers from the local window manufacturer or are you looking online?
