Stronger Access for European Manufacturers

Access to the North American construction market has received a significant boost with ift Rosenheim now officially listed as a recognized testing laboratory by Keystone Certifications in the United States. The move streamlines certification procedures for European manufacturers of windows, doors and façades aiming to enter the US and Canadian markets.

Modern European building products already enjoy a strong reputation in North America for quality, durability and energy performance. However, compliance with American standards — including ASTM, AAMA and NAFS — is a prerequisite for product approval. The new collaboration between ift Rosenheim and Keystone Certifications enables manufacturers to carry out these tests directly in Germany, avoiding the cost and complexity of shipping prototypes overseas.

Recognized Test Procedures

The recognition covers a comprehensive range of standards relevant to windows, doors and glazing, including:

• AAMA/WDMA/CSA 101/I.S.2/A440 (NAFS)
• ASTM E330, E283, E331, E547, F588
• ANSI Z97.1

ift Rosenheim’s inclusion ensures that tests conducted in Germany are accepted by Keystone for certification purposes in the US market. In addition, the institute holds accreditation from the German Accreditation Body (DAkkS) under the number D-PL-11349-01-00, confirming full compliance with international laboratory standards.

Efficiency and Market Advantage

This cooperation represents a decisive step for European manufacturers seeking North American market access. By conducting testing locally under recognized standards, companies can significantly reduce time-to-market and logistical costs while ensuring regulatory compliance.

“The partnership allows European producers to position their products efficiently and confidently in North America,” said Markus Egli of ift Rosenheim. “It’s a practical solution that combines technical quality, international recognition and cost efficiency.”

About Keystone Certifications

Founded in 1998 as an NFRC-licensed inspection agency, Keystone Certifications has since expanded its portfolio to include a wide range of certification and quality assurance programs for energy-efficient and structurally tested products. The organisation holds multiple licenses and accreditations from government and industry bodies and plays a central role in certifying building products throughout North America.

Building Bridges Between Markets

The cooperation between ift Rosenheim and Keystone Certifications strengthens the transatlantic bridge for building component manufacturers. By merging European testing expertise with North American certification requirements, the partnership supports faster, more reliable market entry — helping manufacturers deliver proven, high-performance products to a growing sustainable construction sector across the Atlantic.
