If the insulation is for sound as opposed to thermal, you can install the insulation in one piece behind the wires and then make horizontal slits to let the wires go in halfway. Even for thermal insulation purposes you can slit the paper facing and half of the insulation thickness but then tape the facing back together when you are done.
Full Answer
Does insulation go on before or after wiring?
After the wiring is in place, the insulation can be laid in. Most homes are insulated using batt or roll insulation. Other options, such as spray foam or loose insulation, are also a possibility, but in all cases the insulation needs to be installed after the wiring is done.

How do you insulate around wiring?
When you insulate around wiring, it is important that you fill as much space as possible with insulation. There are two ways to insulate around wires. First, you can tear or cut the insulation sheets in half and lay half behind the wire and half in front. If the wire is too tight to the wall to make that easy, you have a second option.
What is the best order to install electrical and insulation?
Electrical systems and insulation both need to be installed inside the wall cavities of your home, and it is important that they go in in the correct order.

Can you put fiberglass insulation in an electrical box?
Never stuff insulation behind an electrical box. Split the batt to fit neatly behind the box, and then cut the rest to fit around it. Don't pack the gaps around windows. The insulation should be able to expand just enough to fill the cavity without compressing.
Is it safe to lay loft insulation over electric cables?
This is a serious fire-risk. All electrical cables will produce heat. The higher the current (in Amps) the more energy is lost as heat. Adding insulation above a cable like this reduces its current-carrying capacity by 50%.House insulation, electricity cables and fire risk: the good and the bad...https://forum.ovoenergy.com › your-smart-home-139 › h...https://forum.ovoenergy.com › your-smart-home-139 › h...Search for: Is it safe to lay loft insulation over electric cables?

How to protect water pipes from freezing?
Protect pipes from freezing by lagging with foam tubes Lagging simply means adding insulation to the water pipes and is easy to do with foam tubes. It prevents them freezing and also helps any exposed hot water pipes retain their heat when running through unheated parts of the house.
Is Insulation Flammable?
The flammability of insulation is largely dictated by the material used and how it is treated. The most common types of insulation installed in residential structures are listed below.
Can Foam Insulation Be Installed in Existing Walls?
Certain types of foam insulation can be injected into existing wall spaces. The injection process requires special equipment and training. To inject foam insulation into an existing exterior wall requires drilling holes in the exterior wall between the stud spaces. This can lead to some unsightly patch jobs that may detract from your home curb appeal.
Can you Spray Foam Insulation Over Electrical Wires?

Can you use blown in insulation?
Sometimes, when the walls are already all in place it is better to use alternate methods of insulation, such as blown-in insulation. This is particularly useful when you need to fill insulation in around older existing wire systems; even if you don't know exactly where the wires run, the blown-in insulation will simply fill in the gaps.
