Andreas Kaufmann, Internorm Windows UK Ltd. managing director, said: “As a family-owned business, we’re proud to manufacture 100 per cent of our products in Austria, at our three plants in Traun, Sarleinsbach, and Lannach. Our skilled employees are dedicated to ensuring the highest quality standards.”

The company has positioned itself in the premium segment of the market, emphasising energy efficiency, security and design. Its product range includes timber/aluminium and uPVC/aluminium composite systems, as well as entrance doors and lift and slide doors.

Demand for high performance windows and doors has grown in recent years as building regulations have tightened and homeowners have become more aware of the role glazing plays in a building's overall thermal performance. For passive house projects, where airtightness, insulation and the elimination of thermal bridging are critical, high performance windows are a critical element of meeting the standard.

Internorm’s windows have been installed in countless certified passive houses across the UK and Ireland – including umpteen projects published in Passive House Plus.

“At Internorm, sustainability is at the core of everything we do,” Kaufmann said.

“With people spending 90 per cent of their time indoors - two-thirds of that at home - we are committed to reducing our carbon footprint by producing energy-efficient, innovative products that contribute to healthier, more sustainable living.”

The anniversary comes at a time when the fenestration industry is navigating supply chain pressures and increased competition from both European and domestic manufacturers.

Internorm, which describes itself as Europe's largest window brand, manufactures all of its products in Austria and has a presence across the UK and Ireland, where its windows and doors have been specified for a range of renovation, self-build and passive house projects. The company's British subsidiary, Internorm Windows UK, manages sales in the UK, Ireland, Canada and the USA.
