Stop noise coming through your windows with Winsulation Double Glazing
Reducing noise is easy with double glazed window and door systems. As a noise reduction system, double glazing can significantly stop noise by up to 80% in laboratory tests.
The impacts of environmental noise on the quality of human life are a growing concern. Traffic noise can cause cardiovascular disease, cognitive impairment, sleep disturbance, tinnitus, high blood pressure, and antisocial behaviour.
Successful noise reduction with double glazing
What is a double glazed system? Double glazing is a noise reducing system of insulation or soundproofing. Typically called an IGU (insulating glass unit) it comprises two panes of glass, an air gap in the middle, and a specialised frame. The frame, extra glass and air pocket work together as a noise filter to create soundproof insulation between the inside and outside of the window or door.
Standard windows with an ordinary frame and one pane of glass account for a huge amount of noise transmission. With double glazed systems, the window glass, air gap and frames act as a noise reducer. This makes sure that the annoyance of street noise, neighbour noise, traffic noise and even barking dogs can be filtered out.
Our specialised frames are made of either uPVC (supplied by Rehau) or thermally broken aluminium (supplied by Thermeco). Thermally broken aluminium contains a soundproof material that is placed between the inside and outside of the frame and the sash. This creates an insulation buffer against the outside world. Thermally broken aluminium conducts heat/cold/noise a thousand times slower than standard aluminium.
The Weighted Sound Reduction Index (RW) measures the reduction of sound decibels transferred through a single building element i.e. walls or windows. The higher the RW rating, the better the sound insulation. The Sound Transmission Class (STC) reflects the amount of noise that is reduced when sound passes through a window. Both are measurements that are used to measure the level of sound insulation in houses, buildings and apartments.
The table alongside shows common sources of noise and their typical noise level in decibels. Noise suppression can be achieved through double glazed units by up to 80% in laboratory tests. Meaning that the noise of a jackhammer can be reduced to that of a quiet suburban area OR busy office noise can be minimised to a near whisper.
Primary double glazing or secondary double glazing?
Both primary and secondary double glazing are effective sound reduction techniques to stop noise, making your home environment more comfortable and peaceful. With primary double glazing, the entire window system is replaced. Secondary double glazing however, is a method of soundproofing and insulating your home without having to replace your existing windows. Secondary glazing is easily the most cost effective noise removal solution for the majority of situations. It is s fast, simple, and typically requires no changes to the existing window or window dressings.
Noise suppression can be dramatically increased through double glazing. If you’re looking to stop noise through soundproofing or sound reduction solutions, double glazing could be the answer.
*While we have managed to achieve an 80% reduction in noise being transferred through windows, this cannot be guaranteed. This is due to a variety of ceiling, wall and floor materials and construction methods of the home. No claims of on-site performance are made or implied.
