Step 14: Insulation

After the rough-in of the electrical, plumbing, and heating was done, we had it inspected.  Then we have to insulate the walls to keep the cold out in the winter.

There are three parts to the insulation:
1) Wall Insulation
The insulation in the walls comes in a bag of rectangle pieces.  They are easy to fit into the wall between the studs.  Sometimes we have to cut them, but they are easy to cut too.  The hardest part is they are itchy, so we wear white coverall suites to keep the itchy stuff off out skin. 
It only took my team a couple of days to insulate all the walls in the house.

2) Vapor Barrier
The vapor barrier is a plastic sheet that we put on all the walls.  This is to make sure no moisture can get through the wall.  It also helps to keep the spiders out.


3) Attic Insulation
The attic insulation is different because we blow it in using a machine that sounds like a vacuum cleaner.  This has to be done after the drywall (step 15) because the drywall holds the insulation up in the attic.  Jamin helped me do the attic insulation.
