Blacksteel Sound Reduction

Architecture begins where engineering ends - Walter Gropius.

Peace & Quiet

Sound reduction is essential to maintaining peace of mind. In our modern world, however, we often barraged by an increasing din of unwanted background noise. This is not only a problem for an office environment but can also impinge on our comfort within the home. It is a well documented fact that distracting noises reduce our efficiency and increases our stress. Additionally we know that acoustic privacy can be vital –  not only in boardrooms and consulting rooms, but in residential spaces as well.

Modern designers are turning to better technology to address the challenges of combating sound transmission. This includes improved wall and floor construction, as well as high technology glass construction for windows, doors and partitions. 

SOUND REDUS

Sound reduction is essential to maintaining peace of mind in the modern world. More than ever we are barraged by a background din of unwanted noise. It is particularly hard to concentrate when sounds from one space filter into a work environment that is meant to be private. This is especially so in open-plan offices, but as more people are working from home offices, it is a growing problem in the home. Distracting noise reduces efficiency and increases stress. Acoustic privacy is critical not only in boardrooms, consulting rooms, and health care settings but in residential spaces as well.

Which is why all EuroLite interior doors and windows include “Wave Disrupting” sound technology that reduces sound transmission by up to 50% over normal dual or triple pane windows.

EuroLite achieves STC (sound transmission control) ratings of up to 40 by utilizing three proprietary processes:

  1. We utilize slightly different thicknesses of glass, so sound hitting one pane is transmitted at a frequency that does not resonate with the second pane.
  2. Our thermal break system works to dampen sounds passing through the frame.
  3. Our heavy duty ‘4 Seal System’ works to prevent ‘acoustic flanking’, or sound passing around the sash.

Blacksteel Sound Technology

Blacksteel windows, doors, glass partitions include “Wave Disrupting” sound technology to reduce sound transmission by up to 50% over normal dual pane windows. 

  1. We utilize slightly different thicknesses of glass, so sound hitting one pane is transmitted at a frequency that does not resonate with the second pane. This ‘breaks’ the sound wave amplification. 
  2. The addition of a PVB layer, laminated between two glass panes further reduces sound transmission.
  3. Our thermal break system also works to dampen sounds passing through the frame.
  4. Our heavy duty ‘4 Seal System’ works to prevent ‘acoustic flanking’, or sound passing around a sash or door slab.

Depending on your requirement for acoustic privacy, we can work with your architect or builder to achieve the desired results.

About STC

STC or ‘Sound Transmission Class’ is a single number method of rating how well a building element reduces sound transmission. The STC provides a standardized way to compare building materials as well as products such as doors and windows. A higher number indicates more effective sound insulation than a lower number. However, the STC rating uses a logarithmic scale like the ‘Richter Scale’ for earthquakes. An increase from 28 to 38 means that 90% of the noise is reduced. A change from 28 to 43 represents a noise reduction of over 95%. Small increases can mean a lot of extra noise reduction. The increase from 38 to 43 mentioned above doesn’t sound like much (90% versus 95+% in reductions) – but going from 90% to 95% means that 60% of the remaining noise was removed; every number represents a large amount of noise!

Technical solutions for sound reduction depend on the source and type of noise and the path of acoustic transmission. The smallest structural gap can cause a disproportionate reduction in sound proofing. A 0.1% opening will reduce transmission loss from 40 dB to 30 dB, which is typical of walls where the caulking has not been effectively applied.  Partitions that are inadequately sealed or contain back-to-back electrical boxes, untreated recessed lighting or unsealed pipes, also offer significant flanking paths for sound leakage. For this reason, the STC of a building material is not the sole ingredient in providing optimal sound reduction. For commercial or sound studio level sound reduction, we advise consulting with an acoustical engineer.

To give some examples for comparison: a standard wall in most homes has an STC rating of 33, while studio-level soundproofing requires a rating of at least 45. Most rooms is a luxury residential home should have STC ratings of 38-42
