Hello all,
I am in need of some advice before I make a big decision. I have a brand new home (3 mos old). Builder installed Andersen 400 windows. Here is the problem, I back to a busy road with a speed limit of 55 mph although many go at least 70. Mostly cars but also a considerable amount if tractor trailors (semis) and pick ups with loud aftermarket exhaust. Getting a lot of road noise and a tinney sound on the glass.

My Andersen 400 casement windows have an STC of 26 and an OITC of 22.
Pretty low. I think it is a 5/8 size if that sounds right.

Andersen rep reccomended replacing all my sash with new sash with laminated glass which would give me STC of 30 and OITC of 26. For a cost of $400 per sash (about 10 windows). The new windows would still be Andersen 400 but Coastal series. I live in the midwest, no ocean around here but I guess the call this tgeir upgraded STC glass.

Do you think the laminated glass with 4 point STC/OITC increase may help or at least provide a little relief?

Thanks for your feedback! :-)
