EUROPE’S NO. 1 WINDOW BRAND
Internorm has been a family business for 91 years, having developed from a one-man blacksmith‘s shop to the largest internationally active window
brand.During this time we have manufactured over 27 million window and door
units, all 100% made in our production facilities in Traun, Sarleinsbach and
Lannach in Austria. From the creation of the UPVC window and the production
of the timber-aluminium window to today‘s high-tech and ultra-modern design
innovations, our family company has been setting standards all across Europe.
We are pioneers in our field and continue to further develop technology and
innovative ideas.
