LA is a very noisy city.
The drivers are terrible so there is screeching, accidents, and of course lots and lots of honking. And no matter where you live, helicopters are always overhead.
All that plus just living in a big city can cause you to lose sleep or be generally irritated by the constant noise.
At Tashmans we carry a line of windows called Citiquiet which do a fantastic job of giving you a quiet home. Whether you want to replace your old windows completely or get a Citiquiet addition to your existing windows, the change is dramatic with up to 95% noise reduction.
