Spray Foam

Pro-Tight installed the spray foam this week. They started off covering everything that you wouldn't want foam on. Covering outlets is easier than digging it out later. The two components used to make the foam are heated as they are sprayed and give off that heat when they expand. It gets so hot the guys take turn spraying. They started spraying around 7:00 am and would switch out every 45 minutes. By noon they only lasted about 10 minutes. While the insulation keeps out the heat of the sun bearing down on the roof. It also kept the heat in that was generated from the process of spraying the foam. The ventilation fan was the only way to get fresh air upstairs. While spray foam is relatively inert it has it's hazards while it is being sprayed. The vapor accumulated in the apartment and caused symptoms similar to getting the chemicals in my eyes. Those symptoms include "corneal opacity" or blurred vision. It reminds me of swimming in a chlorinated pool. It doesn't hurt and I didn't realize it was happening. Should go away in a few days. They normally don't spray in an area as air tight as this apartment, but it has happened to them before. And it affected all of us. It is something that regular eye protection wouldn't protect you from. If you ever get the opportunity to watch the process make sure you wear goggles.

I'm getting bids to sheet rock this week. And still waiting on the local CO-OP to install the electricity. With 1800 ft. of water line to trench I have plenty to keep me busy.
