发帖数: 20343 | 4 Q: going to roll out attic insulation between the ceiling joists. what do I
do when I come across wires that go through the joists? Can I roll the
insulation over the wires or should I cut it and leave the wire exposed and
start the roll again on the other side of the wire?
A: Heat is the enemy of the insulation on electrical wires. When you put
insulation over the wires, you cause the wires to get warmer, this increases
the resistance of the wires which then causes line loss or also known as
voltage drop. Cut the insulation or put it under the wires, then tape any
cuts with the wire exposed. This is the proper way to do it. Most insulators
, just roll it over the wires, but it will change the amp rating of the
wires. This may or may not be a problem.
A: The best way is to cut the insulation a foot longer than the distance to
the wire, then split the insulation so that it goes above and below the wire
. Start a new piece of insulation tucked tight to the last. If you fill up
the bays, and you could use more insulation go at right angle to the first
layer....more is better
