we have been fumbling thru getting the framing inspection approved. the framing inspection is susposed to be approved before we are allowed to insulate...... however because of the level of complication on this project, several items that need to be addressed for proper fire blocking/caulking have to be postponed till after the insulation is installed so that we dont cover up cavities that need to be insulated. we also have almost a full page of structural related comments from the town of cary to be addressed by the structural engineer in the form of a sealed letter. so, to make along story short, we have the framing inspection partially passed so that we can start insulating, but we will need to have the framing reviewed again before its passed.
after getting multiple prices/quotes on foam insulation, i was really discouraged and was seriously considering using fiberglass. we were running out of time to make a decision, when insulating incorporated, one of the companies that provided us a quote, called back with a better price. it was still more money that i had budgeted for insulation, and more money than i wanted to spend but i feel it will pay for itself over the next few years. the foam installation is extremely interesting. hard to believe how much expansion occurs in less than 30 seconds. the sealing properties of the foam make it an excellent choice to make an air tight envelope. this decision may require us to have a form of mechanical ventilation because there is significantly less air escaping threw the walls. ill deal with that later tho..... for now im just focusing on getting prepared for the insulation, and framing inspections.
you can see in the photos how much prep work is involved. almost everything has to be covered in plastic. all the windows and doors have to be sealed with low expansion foam, and the base plates on all the walls are caulked where they meet the floor. the foam has an extremely high expansion, and is harmful to breathe..... you can tell they take it serious by the way they wear a full tyvec suit, and positive displacement respirator.
