have been using this site for a while but my first post.
We have had an acoustic report done for our new build which requires the bedroom windows to be upgraded from the standard sliding windows to 6.38mm laminated safety glass in acoustically sealed sliding frames.
The project builder we are dealing with has quoted us $2481 for the upgrade.
The windows are
2 x 12-21 sliding windows
1 x 12-3170 sliding window
1 x 15-2120 custom awning window
Does this sound reasonable keeping in mind it is only the price difference between the standard windows and the upgrade?

Depends on the window... looks like $200/m2 and that seems excessive if they are only upgrading the glass and seals. What acoustic level (Rw) are they trying to achieve?

1. For acoustic rated windows, sliding windows are not a good option. Awnings or casement windows are recommended.
2. Builders always have excessive margins for upgraded items.
