Okna is one of players in the vinyl window manufacturing business. The company has a narrower product range than many of its competitors--Okna 400, Okna 500, Okna 800 and Okna 900 windows. However, do not let this lack of a wide product range fool you: Okna windows have received very good reviews from homeowners, in terms of thermal efficiency and providing value for money.
