Acoustic Insulation
When soundproofing is paramount, we recommend using a different glass thickness in your secondary glazing than that of your existing windows, this decrease sound reverberation. An air cavity of 150mm to 200mm and special acoustic glass provides maximum noise reduction often reducing noise levels by up to 80% (54dB).

Thermal Insulation
For maximum thermal performance, we specify "low E" glass, which has a special heat-reflecting coating to help keep heat within the room. A recommended air cavity of up to 80mm is advised. We've helped thousands of homeowners and commercial clients over the past 20 years. We'd like to think that we can help you too.
