Internorm International GmbH

Internorm International GmbH, based in Traun in Upper Austria, is one of Europe's major window and door brands, manufacturing in Austria and distributing through partners in many countries. Its range covers PVC, PVC-aluminium and timber-aluminium windows, entrance doors and glazing solutions designed for thermal comfort, security and contemporary design.

For anyone planning a building envelope, this listing helps compare systems, finishes and performance before requesting a quote: pay attention to frame type, glazing, integrated solar shading and insulation level, since these details affect both energy use and long-term maintenance.

Before deciding, ask an authorised distributor for advice and check delivery times, warranties and after-sales service, especially in renovations where existing openings and the condition of the reveal can change the recommended solution.
