Leading the Way in Curtainwalls Since 1959

For almost 40 years, Midwest Curtainwalls has been designing, engineering, testing and manufacturing curtainwall systems that perform. We've taken on projects of all shapes and sizes, upholding each designer's vision as we deliver aesthetic excellence, technical precision and incomparable quality assurance.

Midwest has been solving tough curtainwall challenges since 1978. Through the decades, our capabilities have evolved to meet the ever-changing needs of architects, owners, developers, contractors, curtainwall consultants, and curtainwall and glazing contractors, who are our direct clients. Our business partners know that our technical and production staff members – many with 20+ years of experience – are committed to developing custom solutions and bringing curtainwalls of exceptional quality and performance to their projects.

I have had the pleasure of working with Don Kelly for over a decade. We have completed successful projects in the past, and we are doing the largest project in my company’s history with Midwest Curtainwalls in 2015. Don’s personal knowledge of the industry, and expertise in unitized curtainwall is an extremely valuable asset that BAGS uses to expand our manufacturing and engineering capacity. We can do it ourselves, but many times Don and his team at Midwest can do it better and faster.

The Next Generation of Family Business.

Authority National Supply, LLC. (ANS) was formally organized in 2012. ANS was founded to concentrate on negotiating and purchasing tasks that independents have struggled with on their own. ANS provides the opportunity to partner with key manufacturers that recognize the efficiency of a central billing business model. We purchase a variety of exterior building products including: roofing, siding, windows and tools, on behalf of our shareholders.

In the past we have seen our margins erode as more national players have opened or purchased facilities in our area. We feel we have been competing on an uneven playing field. ANS has given us the leverage of a larger organization to help with margins and product opportunities. ANS has given us the outlook for a better future for our family-owned business.
