Window is an integral part of the Buk frame (no further window installation is necessary.) Large exterior fins ensure the Perma-Buk will stay secure in the concrete. Sloped sill promotes water drainage. Glazed with 3/4" dual pane insulating glass. Units fully weather-stripped to protect against air and water infiltration. "Perma-Buk III' is fully braced and covered with protective film to prevent against frame distortion, damage, and post-construction clean-up
