Noise Reducing Glazing – A Guide

Improvements in manufacturing techniques have not only made noise reducing glazing much more efficient at cancelling noise, but also considerably more cost-effective than you might imagine.

 

A specialized glazing system, also occasionally referred to as acoustic glass, it is used in pre-fitted systems and can also be installed in existing window frames. Due to its physical properties, ‘normal’ glass is an extremely efficient conductor of sound, great for keeping out wind and rain but of little value as an insulator against noise.

 

The science behind soundproof glazing is relatively simple. The requirement is obviously to prevent as much sound as possible from penetrating the glass and there are four major contributory factors that effect this.

The thickness of the glass, the quality of the glass, the space between glass panes and the sound dampening elements contained in the interlayers.

There is also a fifth element to consider, the quality of the fitting.

 

Thickness – It seems obvious that the thicker the glass, the greater the soundproofing will be, but this is not always the case. Sometimes two sheets of glass of an identical thickness will actually amplify sound rather than reduce it.

Quality – Hugo Carter fit the very finest noise reducing glass from market leaders Pilkington and Saint Gobain to achieve truly remarkable results.

Spacing – The correct distance between the sheets of glass is guaranteed by our engineers. Factors taken into consideration include available space, noise reduction requirements and budget. Too much space between the sheets and the windows, while efficient, may be too wide for fitting, too little space and noise cancelling efficiency is lost.

Interlayers – Depending upon the type of unit and the noise cancelling requirement, consideration is given to the use of inert gases such as argon and krypton. As ever, Hugo Carter will advise on the most appropriate for your requirement.

Fitting – Here at Hugo Carter we have developed a system that is unique to us, our sash and casement windows feature an engineered solution that we ourselves have developed to achieve astonishing noise reduction without compromising on the finished look.

Thermal Efficiency

We often focus on the noise reducing capabilities of our glazing products and of course, this is a major consideration for our clients. We should not however overlook the cost-savings available as a result of fitting Hugo Carter windows.

Our units are designed to be fully insulated, cold air cannot get in and warm air cannot get out because there are no gaps between frame and glazing. The inner pane of glass is ‘soft-coated’ which means it reflects the heat back to the room to further improve thermal efficiency. From an environmental and financial perspective this means that you will not be paying to heat your garden or the street outside.

Thermal Efficiency is measured by calculating the proportion of light allowed through the glass, the measure of heat loss and the percentage of solar radiant heat allowed through the glass.

The important part is that every unit is given a rating between A and F or 1-6 based on these efficiencies and as we hope you would imagine, Hugo Carter are experts in efficiency.

 

Safety and Security

The effectiveness of high quality glazing as a security feature cannot be overlooked and Hugo Carter install windows and doors that property owners can rely upon to act as an efficient barrier. Safety advisors will always suggest that glazed units should feature glass that will not shatter on impact and this is true of every unit we fit.

More importantly the added benefit of laminated glazing is security. Windows equipped with such glazing are much harder to break into.

 

Interior uses

Noise reducing glazing can be used effectively in home or office environments to separate rooms and work spaces, more aesthetically pleasing than a wall and offering more light while maintaining acoustic integrity.
