Noise in Steel frames

What makes the Supaloc system so quiet

Understanding noise in house framing and how Supaloc is engineered to eliminate such problems.

It is often said that Steel frames are noisy. Unfortunately this myth has persisted through the years while technology, engineering and design have advanced. In correction to this statement Supaloc Steel frames (unlike timber and other steel frames) are engineered to eliminate noise created with natural movement. This is best demonstrated by understanding how each material creates noise and how Supaloc are engineered to eliminate such issues.



In residential construction timber frames are butt joined and fixed with nails. Timber is a natural cellulose product and reacts to atmospheric moisture, heat and cold it shrinks and warps. As the timber expands and contracts, the butt joints and nails allow movement of the frame and create noise.


Noise is created by movement between members (both steel and timber). Other steel framing systems in the market connect members together by welding or with the use of tek screws or bolts. The surface area that touches between members is allowed to shift with such a connection and thus generates noise.


Supaloc has a dedicated team which has conducted over 20 years of research and development. After experiencing noise in the past, the team engineered a dimpled bolt & rivet connection that ensures less contact between members and reduced movement that would traditionally generate noise.

The patented (unique) Supaloc Truss connection has been tested by the University of Sydney’s Centre for Advanced Structural Engineering, to prove there was no movement between members at this connection resulting in silence. Even under extreme pressure the connection never moves.
