General Information: Lincoln Wood Products was founded in 1947 by Carl and Jane Bierman. Based in Merrill, Wis., the privately owned company manufactures a complete line of wood windows and patio doors for new construction, remodeling and light commercial projects. In 1994, Carl and Jane formed a sister company, Timeline Vinyl Products, to offer an upscale all vinyl window and patio door product line. Today, the companies occupy four plants totaling over 500,000 square feet of manufacturing space. Lincoln and Timeline windows and patio doors are marketed through a network of over 400 independent distributors throughout the United States and Canada. Throughout the past year, Lincoln and Timeline have invested heavily to expand manufacturing capabilities and to develop new products. For 2013, Timeline will be launching a totally redesigned product line focused on performance and aesthetics, while Lincoln will be introducing several new innovative products focused on the high-end markets.
