Anyone who has been to our house will know that we live on a busy road. It's especially noisy in rush hour, even though it's not a main drag as it were. People use it to get around the traffic lights on Libertador and on the weekends it's jammed packed with cyclists, joggers and deliver bikes.
Our current windows are single glazed, probably over 25 years old and of terrible grey aluminium. It's so noisy sometimes that I have to wear headphones to watch TV.
Anyway, they are each around 2.5m x 1.5m in size and we've received three quotes, ranging in price by a staggering amount.
For both, the prices are between USD 6000 and USD2000. No prizes for guessing which one we'll go for and fortunately, the cheaper company is recommended by our architect in-laws.
I know double glazing isn't used as much in BA, but in our case it's now become a necessity.
