It was surprisingly simple.
- Emptied out the first section of the attic that we use as storage.
- Rearranged what little batts I had and pushed them together at the end of the house in the third section of the attic. This resulted in about 25% of the attic having R30 insulation.
- Covered up the top of closed off staircase that is now a bathroom pantry. Cold air from this staircase was really bad. It effected the second floor and the first floor. Sealing this up really helped.
- Blew in the insulation over the existing batts which gave me R60 afterwards and then blew in insulation throughout the rest of the two sections of the attic to about R49 (less in some areas)
- Built a simple sub-floor frame in the first section to hold two layers of 2" thick insulation board with OSB board covering it. This section was kind of half-assed as my skill level for something like this is non-existent, but it is only needed to hold storage so I am not that concerned bout the strength of the sub-flooring. With insulation board, OSB, and some insulation carpet padding, it brings that area up to about R30.
- Board off section two and three from section one with insualtion board to prevent cald air from coming into that section.
- Frame out a box with 2x4s and OSB board with 4" of insulation board to block off the attic staircase. This will prevent cold air from entering the master bedroom and kitchen.
The first section is not completed yet. The subflooring framework is complete, the boards are cut and in place, but the OSB board is not laid on topyet and the block off for the stair case is not done. When that is done I expect the Encore in the kitchen will be a lot more efficient at heating that area. As it is, I have seen a big difference in terms of heat retention and comfort.
Altogether it cost about $950 to do. 32 bags of blown-in insulation at $12 a bag. The hopper was a free rental with 20 bags purchased, the insulation board was about $350 and then about $200 in 2x4s and OSB board.
This fall I will probably blow in another 20 bags just to be sure everything in the second and third sections are up to R60 and that I didn't miss any spots.
The blower was easy to use. Would have been easier if it weren't for my house being its typical pain in the ass. Do to the design of the home, it required me to bring the hopper into the attic which meant me lifting the hopper up two flights of stairs. Super fun.
