We're ready

The insulation in our local supplier's warehouse pending delivery tomorrow

Cleaned up

We cleared everything out in order to store the insulation shown in the top photo inside the house once its delivered

Joe finished off the last of the baffles in the roof over the 2nd floor guest room

After what seems like such a long time we are finally ready to insulate.

On Tuesday morning, Bill Hulstrunk is going to come and perform a blower door test on the house to check for air leaks. From what I've read, air leakage can cause anywhere from 30 percent to 50 percent of the heat loss in some homes.

The blower door test is a proceedure where you negativly pressurize the house and measures the rate of airflow required to maintain the building at a certain pressure. We'll be able to quantify the area of leakage. Vent ducts and other intentional openings are all closed so the house is otherwise sealed.

Typically a blower door test is done after insulating has occurred, but I want to know what leaks are present before we insulate while we can still get at them. Whatever the result, the cellulose insulation will be working for us as an air barrier in the walls, so its a sure thing that our numbers will go up. I would expect most leakage would be around the windows and doors, so we'll be checking for that.

Joe finished up the baffles in the long roof rafter bays and I spent the better part of Friday sealing every imaginable air passage around the windows and doors. I've been half-joking with folks that I'll pay $10 bucks to anyone who can find a hole anywhere in the house.

The first batch of insulation will delivered tomorrow.
