Reduce noise levels up to 80%
Secondary glazing’s secret is a sound blocking air cavity that is created which drastically reduces noise, teamed with acoustic glass Granada can make a diesel bus sound like an electric car. To achieve the best acoustic performance we advise, an air cavity of up to 200mm glass to glass and the specification of an acoustic glass.
Increase thermal performance up to 65%
Draughty windows can make a room feel uncomfortable. Secondary glazing acts as a second barrier to the elements often increasing thermal performance. Not only will you have a naturally warmer home but you will even develop a more economical home, by spending less on your heating bills and keeping warmth locked in.
