About Timeline


Timeline Vinyl Products, Inc. is a manufacturer of high quality vinyl windows and patio doors for new construction, remodeling and light commercial projects.

Based in Merrill, Wisconsin, the privately owned company engineers windows and patio doors for visual appeal as well as outstanding performance and backs it up with exceptional customer service before and after the sale. Timeline windows and patio doors are marketed through a network of nearly 300 independent distributors throughout the U.S. and Canada.

In the early 1990's, the market was opening up for an all vinyl window and patio door product line. Being a longstanding wood window manufacturer didn't deter the Bierman's from recognizing the benefits of an all vinyl product. They saw how vinyl windows could complement the traditional wood and aluminum clad wood offerings from Lincoln. In 1994, after much research, Timeline Vinyl Products, Inc. was established as a sister company to Lincoln.

Lincoln Wood Products, Inc.

In 1947, Carl & Jane Bierman purchased and renovated an old dairy farm and Lincoln Wood Products began. At the time, Carl had 10 years experience in the millwork industry, and together with his wife Jane, shared a dream and a desire to succeed. They had very firm ideas on how the business should be run and worked hard to establish their ideals. As the company grew, the original building was expanded several times and new facilities were purchased and built. Today the company encompasses over 500,000 square feet of manufacturing space in multiple facilities in Merrill, Wisconsin.

Customer service is the #1 priority and is always evident at Lincoln. Another company focus is the continual evolution of our product lines. We are constantly integrating technological improvements and expanding our product line through extensive research & development. Our staff utilizes state-of-the-art fabrication equipment and in-house testing facilities to design and build high quality fenestration products. Lincoln products are certified and verified by independent testing firms.

After the passing of both Carl and Jane Bierman,  the finely crafted windows and patio doors still reflect the company’s long-standing tradition of quality craftsmanship.  Their belief and commitment to value, along with a strong work ethic, has been passed down to the many generations of employees and continues to be an inspiration and driving force in the company today.
