IV79 Standard

Product: Bildau & Bussmann

Material: Wood

The IV79 Standard is our basic window. Utilizing our internally produced and quality assured glue-laminated lumber provides superior strength, stability, and resistance to warping and surface cracking. The aluminum sash drip channels water away from the sash and insures that the window remains impervious to the elements. The sash is designed to accommodate 3-layer glass, offering a window assembly with superior energy conservation characteristics.
