Lammin Ikkuna Oy – Windows for Finnish homes for 50 years

The roots of Lammin Ikkuna go back to 1969 when a window factory was established in Lammi, in the province of Tavastia Proper. Over the years, the factory has undergone many changes, but one thing has remained the same: from the beginning the basic idea behind our operations has been the efficient fabrication of practical and durable windows. 

Today, Lammin Ikkuna employs about 110 people. In addition to Lammi, our manufacturing activities have spread to Kangasniemi, where we manufacture doors. Our service network covers all Finland.

Customer needs as a basis for business

Our business is based on high-quality windows and doors that meet the challenges of the time and the needs of every customer. Our mission is to help the customer to create a practical and beautiful home where he or she feels at home. In our business, we aim at sustainable quality and practical products. This is reflected in customer satisfaction: Lammin windows and doors receive the least customer complaints in the industry. 

Continuous development work for the benefit of our customers

In our activities, we focus on continuous manufacturing and product improvement. For decades, we have been at the forefront of the development of window and door products and have brought many important innovations to Finland: We were the first in Finland to start the serial production of custom-made windows in the 1970s. We were the first in Finland to introduce electrostatic painting technology for wooden parts in 1989. In 2008, we received the INNOSUOMI Award for recognition of Eko Watti, the first low-energy window on the market. 

Windows and doors for northern conditions from domestic materials

We have designed our windows and doors for Finnish weather conditions, and all our products have the right to carry the Key Flag® symbol. Our main market is Finland, and our products are also used in other regions with northern weather conditions. 

In our activities, we invest in Finnish work and Finnish raw materials. Our windows and doors are manufactured using exclusively Finnish wood. Each of our products shows a strong pride in Finnish manufacturing. We cherish the Finnish nature: we recycle efficiently the waste generated at the factory and supply our waste wood to energy production.

Our expertise is visible to our customers in their daily life in the form of doors and windows that function just as they should. That’s why Lammin windows and doors are the right choice for every Finnish home.
