Founded in 1978

Only the memory of the clucking of chickens was left behind in the former henhouse in Outokumpu when Pohjois-Karjalan Lasipalvelu Ky set up its window renovation business there in 1978.

At first, the operating area covered only North Karelia in Finland. The business first went through a rough patch, and it was difficult to even cover the costs with earnings. In hopes of a better future, the company moved a little more south to Kymenlaakso in 1981. Under the new name of Ikkunanikkarit Ky, the company swiftly established its position as the most capable window renovator of single-family houses and high-rise blocks. The overheated building sector and resulting recession opened up new possibilities for the company.

A new concept was launched, something totally new and never seen before anywhere in the world. In no time, Lumon balcony and patio glass became a household name that “breathed new life” into balconies and patios of buildings, as our slogan put it at that time.


Today, Lumon is a rapidly globalizing professional in the balcony facade, patio cover, and sunroom business. The company’s elegant and modern touch is visible in the balcony facades of city apartments and the sunrooms of detached homes. We at Lumon believe in innovation, technology, and teamwork.


In the future, Lumon will be a genuinely worldwide modernizer of the urban landscape, with innovations admired by architects and builders. Lumon will receive contact requests from all over the world. Those taking part in our meetings and training lessons have already experienced the hodgepodge of cultural diversity and different languages from American English to Chinese.
