Loewen Windows

Loewen is a Canadian manufacturer of wood window and door systems for residential and light commercial applications. The company uses Douglas fir and mahogany in its products. As of 2025, it had a network of several hundred dealers across North America and employed approximately 700 people.

Loewen was founded in 1905 by Cornelius Toews Loewen in Steinbach, Manitoba, as Loewen Millwork.^[2] Early products included church pews and beekeeping equipment. From the 1930s through the 1940s the company shifted to manufacturing pre-built windows and doors to supply the post-war boom in housing construction.

In the 1990s, Loewen expanded into the United States and became a supplier of custom wood windows and doors. Following the 2008 financial crisis, Loewen Windows lost 90% of its business and was forced to cut the employees from 1,700 down to 500.^[3] In 2010, the business was sold from the local Loewen family to VKR Holding A/S, an investment company based in Denmark.^[4] A few years later, the company was purchased back from VKR Holding A/S by brothers Clyde and Charles Loewen in 2013, with support from other investors.^[3] The window manufacturer continued to sustain itself despite additional economic troubles during the COVID-19 pandemic and the tariffs enacted by Donald Trump on Canada in 2025. As of 2025, Loewen Windows exports approximately 85% of its products to the United States, making it vulnerable to economic conditions there.^[1]
