## Questions & Answers

**Q: Hi could i use this to lay under kitchen cupboards where i have drafts coming up? especilly those aroudn the oven where have electrical wires? regards**
A: Hi There,

Thank you for your enquiry.

I wouldn't recommend putting insulation around wires as that could become a possible hazard if they overheat.

Please let me know if there is anything else I can assist you with.

Kind Regards,
