It is perfectly safe for household insulation to touch wires provided the wires or cables are electrically insulated. There also are techniques to make insulation fit better around wires. However, under no circumstances should thermal insulation make contact with live uninsulated wires and cables.

Should wires be insulated?

Insulation resists electrical leakage, which prevents the wire’s current from coming into contact with other wires and cables nearby. It also preserves the material integrity of the wire by protecting against environmental threats such as water and heat.

Why is there insulation on wires?

Insulation is used around electric wires to protect the wire from the environment or the environment (like people) from the wire. … Exposure to water can corrode wires, increasing their resistance, which in turn creates heat buildup the system was not designed for – potentially causing fires.
