Acoustic Wall Ties
Acoustic Wall Ties (PDF, 957 KB)
While standard cavity wall ties create a solid connection through which sound waves can travel, Ancon Acoustic Wall Ties feature a highly engineered, pre-compressed, acoustic isolation element.
Products in this range provide the necessary structural performance (Type 3 to PD6697), while minimising the transfer of airborne noise and vibration.
The full product range which includes CE-marked cavity wall ties, frame cramps and partition ties, are suitable for cavity widths up to 175mm.
- Recording studios
- Concert venues
- Music rooms
- Residential developments
- Mixed-use developments
- Industrial units
The acoustic performance of this range is far superior to other wall tie types and is the result of a carefully engineered balance between mechanical stiffness and high acoustic resilience.
|Ancon ACOU Tie||139 Hz||2.15 MN/m3|
When considering sound insulation in buildings, the range of frequencies considered are generally between 50Hz and 5000Hz and these are normally banded into the low frequency range [50 – 200Hz], mid-frequency range [201 – 1000Hz] and high frequency range [1001 – 5000Hz]. Ancon Acoustic Wall Ties have been designed to fall within the lowest band.
Approved Document E specifies the use of Type A ties in separating/party walls of new build residential developments in England and Wales. Type A ties must have a dynamic stiffness of less than 4.8 MN/m3. The dynamic stiffness of most Type 4 wire wall ties is only marginally below this threshold at a standard tie density of 2.5 ties/m2. In contrast, the Ancon Type 3 Acoustic Wall Tie range, with a comparable dynamic stiffness of just 2.15 MN/m3 offers a significant improvement over other Type A wall ties.
This is a mandatory requirement for wall ties. A CE Declaration of Performance can be downloaded from this site or is available on request, in compliance with the EU Construction Products Regulation.
