Image Number 6 for United States Patent #8230651.
A window frame is manufactured as an integral unit comprising a frame body, at least one nailing flange secured to the frame perimeter, and a strip of tape secured to the nailing flanges with the outer portion of the tape extending beyond the outer edge of the flange. In another embodiment, individual nailing flanges are manufactured and delivered on site, including a strip of tape secured to the nailing flange with an outer portion of the tape extending beyond the outer edge of the flange. The installer first secures such pre-taped flanges to the window frame body, before nailing the resulting window frame unit to the wall. With both embodiments, the window frame unit is first fit into the window penetration in the wall, with the nailing flanges and tape overlapping the wall. Each flange is nailed to the wall by folding back the outer, unattached portion of the tape, thereby exposing the nail holes on the flange, and driving nails there though into the wall. The backing on the folded outer portion of the tape is removed, exposing the adhesive side, which is then laid over the remainder of the flange to cover the nails and over a portion of the wall immediately surrounding the outer edge of the flange.
