Can services be installed in SIP walls?
No. SIP panels are a thermally efficient, airtight product and perform best without services running through them.
We would always recommend the use of a counter batten to create a service void behind the panel so that services such as electrics and plumbing can be positioned without penetrating the SIP envelope itself.
