From the early beginnings to today.

In the 28 years of its existence, MIK expanded its manufacturing capacity twice and became one of the top manufacturers of PVC doors and windows. Owing to its creative and competent staff, efficient management and firm values, the fledgling company grew into what it is today: a company with almost 200 employees and a 17% share of the Slovenian PVC windows market. Today, MIK is more than a manufacturer of high-quality windows - we change the way you see the world.
