Can I recess cables into Recticel PIR insulation boards?

Category: DIY

Cables should not be recessed into the insulation boards. They may be laid between two layers of boards with the cabling oversized to accommodate for an increase in operating temperature. If cables penetrate an insulation layer, PIR will have no detrimental effect on cable sheathing.  

Further guidance on the above should be obtained from a qualified electrician.
