Preparations for the windows

On Wednesday, the installer will start to put in the doors and windows. What might look like a simple straightforward action is in reality a sequential process that involves a number of steps that need to take place before the windows and doors go in. Take the sliding glass doors in the living room for example:
These sliders provide access to the deck area which uses cantilever beams that backspan into the house. cantilever beams are nice to look at, since they don't come with the typical heavy looking post and girder structure in front of the house, but they go back inside the building and thus they need to be protected from decay and insects. In order to do that, we had to flash around each of the beams with a self adhering waterproof membrane (called bituthene in construction), over that membrane, we installed the joist jackets (see photo) and over that goes a sheet metal beam flashing that protects the beam-to wall connection from water damage. On top of that flashing goes the door sill pan and then finally the door.
So, we are understandably excited about out new doors and windows-and tomorrow, we will see the first ones in place!
