Does foam cavity wall insulation have any detrimental effects on PVC cabling?

Foam cavity wall insulation can potentially have detrimental effects on PVC cabling if the insulation material contains chemicals that may degrade the PVC over time. Certain types of foam may emit gases or have properties that could lead to corrosion or deterioration of the cabling. Additionally, if the insulation is improperly installed, it could create moisture issues that may further affect the integrity of the PVC. It's important to ensure compatibility between insulation materials and any electrical components during installation.
