H Window

hwindowflatThe first prototype of the H Window was developed by Harald Kvasnes, inventor of the Spilka fully reversible projecting hinge, in Aalesund, Norway, in 1959. The idea was to have a window with a sash that would fully reverse without projecting inside the room, allowing window treatments to remain undisturbed, when cleaning the window.

During 1959, the first year of operations, only 200 H Windows were sold. In 1960 Norwegian window manufacturers signed up as H-licensees. In 1970 the H hardware was greatly improved, which led to the first H Window licensees abroad in 1972.

The first sales to the United Kingdom were in 1979, and in 1984 Spilka UK was established to sell and distribute Spilka hardware throughout the UK.

In 1987 the H Window Company in Monticello, Minnesota, was established as a pilot program to build an aluminum/wood composite window using Spilka hardware to see if the fully reversible concept would be accepted in North America as it is in Northern Europe. The concept and hardware being virtually unknown in North America, along with having to learn the North American market, resulted in a slow start, however since, the H Window Company has proved that the concept and their window has been accepted residentially and commercially for both new construction and renovation markets. The H Window Company now sells their products residentially and commercially through a trained authorized dealer network, focusing in the upper-mid-west states, but also serving major cities throughout the United States.

In 1999 the Spilka projecting hinge celebrated its 40th Anniversary with over 14 million pairs of hinges on H Windows and other windows in 12 different countries throughout the world.

In 2001 some of the assets of the H Window Company were purchased by a group of businessmen and financial consultants with a history of operating successful businesses. In addition to the American investors, a group of Norwegian investors remain a part of the company. The new name of the company is H Window Company, LLC., and the business was relocated to Ashland, Wisconsin in March of 2001.  In 2002 the H Window Company celebrated 15 years of operation in the United States.

H Window Company is actively designing the next generation of windows, which will be manufactured in Ashland, using totally automated machinery and equipment.
