Internal wall make up query

[davejura]

Our architect has specified the following make up inside the OSB of the kit. 100mm rigid insulation (we have upped it to 140mm), VCL, 25mm rigid insulation (we have upped to 30mm), 38mm sw batten service void, 12mm plaster board. My query is should the VCL not be on the warm side of the 30mm rigid insulation instead of the "cold" side? We are using Glidevale Protect and the picture on the packaging shows it directly below the battens (but doesn't show the extra 30mm of insulation). Just wondering if it actually matters which way it is done? Thanks.
