Dear Martin;
It is documented every day in my home where we cannot hear cars pull up on our gravel driveway. But many of the SIPA manufacturing members have extensive testing where sound attenuation is concerned. SIPs generally perform better due to the low air infiltration levels that are the nature of the product or system. Is this for a commercial or residential project? If commercial, what are the STC requirements? It is easy to get high STC ratings by adding mass, like additional drywall to the interior skin. Windows and doors have a very detrimental effect on sound attenuation, but it can be somewhat mitigated by adding mass to the outside, like brick. Let me know what your requirements are and let's get a "sound" dialog going!
Good Luck!

Jim
I'm working for a UK company who are in the process of kick starting SIP panel methodology over here. Much of the info gleaned from your own site (and many of your members) has been invaluable to me in hardening up my convictions that this is the right way to go, so thanks for that.
As far as what type of construction - well principally residential but not exclusively so. We will drywall internally and our industry is unlikely to allow us to start off with anything other than a brick skin externally.
I'm not familiar with STC - I assume it is Sound Transfer or something.... maybe you can help me out on that.
I think I'm really looking for some like-for-like comparisons, if that's not too simplistic.
Kind regards
Martin Coult

I've seen on the SIPA video mention of the fact that SIPs are acoustically better performers that stick panels?
Has this been documented anywhere and if so where?
Thanks

Martin, STC stands for Sound Transmission Coefficient. It is the fraction of the sound energy striking a structure that is transmitted through it.
Individual products often have STC ratings associated with them. What is more useful is the STC rating of complete building assemblies--wall or roof systems, for example. But as Jim Tracy pointed out, the windows and doors can have a disproportionate impact on a wall assembly; the more windows you have, the less beneficial the sound dampening impact provided by the rest of the building assembly. Those familiar with building assembly STC ratings are particularly invited to comment.

Martin,
Sorry to gatecrash but I'm in the UK too and looking to build with SIP's and just wondered if we could have a chat.
