To insulate an attic, lay down a layer of vapor barrier, and then install rolls of blanket insulation. Wear gloves and proper clothing to protect yourself from the fibers in the insulation, and do not take the insulation out of its packaging until you are ready to use it.
- Install a layer of vapor barrier
Lay down a layer of vapor barrier in between the open studs on the wall, and secure it with a staple gun. Use a utility knife to make cutouts for electrical wires.
- Install the insulation
Roll out the insulation on top of the vapor barrier layer, ensuring it's secure between the studs and not too compressed.
- Remove electrical wires
Cut and remove electrical wires from underneath the insulation, and lay them on top of the insulation to prevent them from overheating.
- Install a second layer of insulation
Check to see if your area requires a second layer of insulation. If so, lay it over the first layer at a perpendicular right angle. Move the wires on top of the second layer.
- Insulate the pipes
Wrap water pipes in pipe insulation, and secure the insulation with proprietary clips. Cut the insulation at 45-degree angles to cover corners.
