About Internorm

We are a strong family business

“Internorm has been a family business for the last 85 years and has developed from a one-man locksmith’s to the largest internationally active window brand. The challenge to further develop the trend of contemporary architecture and realise it in highest quality is our aim. We are proud that our products are 100% made in Austria. Openness and honesty characterise our business culture”.

High-quality windows and doors from Austria

Internorm products stand for excellent quality, innovative technologies and individual design possibilities. As an Austrian business we are continuously setting new standards in the window and entrance door market. Our employees are manufacturing your dream windows and doors in our three production sites in Austria (Traun, Sarleinsbach and Lannach). The “total window system concept” is completely in our own hands – from research and development, our own extrusion, glass production and ultra-modern, sophisticated production technologies to logistics.

  • Our employees are specialists who have a love for detail and act with much passion and inventiveness.
  • Our company-own research department is continuously developing new products and technologies so that we can offer you even more comfort and security.
