The science of noise abatement is based upon the interruption of noise travelling from the noise source to a particular receptor, for example the most exposed facade of a building. Windows and doors, however, can often be the weakest link in the isolation of noise from outside the home.


It sounds simple, but effective sound insulating materials for windows must meet many requirements in addition to acoustic performance, such as withstanding long term weather and traffic exposure, attractive appearance, cost effectiveness and increasingly end-of-design-life recyclability.

Double glazing is one of the most effective barriers against sound, and combined with uPVC window frame systems can reduce perceived noise by up to 80% (~45dB).

Double glazing accommodates a variety of glass thickness and types allowing the product to reach high acoustic control requirements. Using two (or more) layers of glazing increases noise reduction at most frequencies, but by how much also depends on the space between the layers. In order to improve sound insulation, larger air spaces between glazing units, from about 20 to 100 mm, are better.

Windows with good weather sealing are essential for effective sound insulation. uPVC window profiles are welded and have multiple chamber construction. These two factors combined with the thickness of glass, provide the finished window with excellent acoustic insulation, reflecting sound waves before they have the opportunity to create vibrations and noise.

Noise reductions of up to 40-45dB can improve your sleep, decrease stress, improve a work environment and concentration, and add re-sale value to your home[/vc_column_text][/vc_column][/vc_row]
