Diligence paid to sealing techniques, whether in windows, doors, or elsewhere is crucial in creating an airtight enclosure and achieving the energy performance. Flashing And Seaming Tape.
The first steps in the process involve prepping the rough opening. The carpenters have to fill in the extra pieces above the window to flush things out.
Dave: 'We like to install windows over a sloped sill, so we use beveled siding. I'll put a couple of nails in there to hold it in place because we will be shimming the window on this and putting a peel-and-stick membrane on it.'
Some tapes can stretch around corners, but Dave’s going to demonstrate with a standard, non-flexible flashing tape.
Dave: 'You see there's a little piece of plastic inside, like a fishing line.'
First, he splits the release sheet.
Dave: 'Pull that out.'
He works from the center out to either side, keeping the flashing tape along the inside edge of the window.
Dave: 'Later on we're going to put 4 inches of foam on this house. So we'll put another piece [of flashing] on; we want to be able to go out over the 4 inches of foam and turn down.'

We're giving the corner, the weakest point, triple coverage.
