It would be much better to buy a roll of the aluminum backed automotive sound deadening material that is made for these applications. **Q: Where is this made?** A: All the raw material and manufacturing is done right here in the USA. **Q: Is it safe for this to touch a live wire?** A: It’s a sound and fire rated acoustical putty pads. I’m not sure how safe it is but always switch the circuit off before working on live wires. **Q: Can you apply to top of recessed can lights?** A: Yes, that would be a great application for this product. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Add-On to Improve Air Sealing and Reduce Noise Transfer *by L***H on October 17, 2025* Great for air sealing.
