Did you have RC2 windows installed?

Hi,



for "real RC2", meaning with the laminated safety glass panes? That's really cheap...

Best regards,

Andreas

Correct.

It seems there are also different variants of VSG. One provider offers 9 mm on the outside (3 panes of 3mm glued together with 2 films); the other offers 8 mm on the outside (2 panes of 4mm glued together with 1 film). Both are called A3 glass. Then there is also the additional bonding of the panes in the frame, naturally lockable handles, mushroom heads all around, as well as installation with material according to RC2 guidelines.

Additionally, we are upgrading in terms of sound insulation, so that the outer glass layer, depending on the room, has 10 or sometimes 12 mm instead of 8 mm. As a result, the designation for the safety glass in the revised offer changed from A3 to P4A (actually the older designation). I am currently dealing with the details behind this.

Originally, the glazing of a "normal" triple-glazed window looked like this: 4/12/4/12/4 mm (would achieve 32 dB)
For RC2 it looked like this: 8/12/4/12/4 mm (would achieve 37 dB)
Combined with our sound insulation requirements:
Office, sound reduction index glass 41 dB: 6/14/4/14/4 mm (here I want to understand why the outer pane, which should be VSG, is only 6 mm. I think that is no longer "real" RC2.)
Living rooms, sound reduction index 45 dB: 10/12/8/12/8
Bedrooms, sound reduction index 49 dB: 12/12/4/12/8
All in the 82 profile.

In addition, heavy foil with a sound reduction index of 44 dB is installed in all roller shutter boxes, because the rest of the upgrade would otherwise be pointless. So these will be quite "thick" windows as far as the glazing is concerned.

The surcharge is free of charge, but you can really only judge that if you know the reference price.

Yes. I also asked about that directly.



Do you mean the effort compared to a normal window is large? From the outside, I don’t really find it that big.
- outside instead of a normal pane 2 or 3 bonded with film
- panes additionally glued in the frame
- mushroom heads are "pennies"
- special material to connect the frame with the wall as well as backing/additional protection of these connections

A bit more material and labor, ok, but nothing that would justify a price explosion, right?
