Next-Level Security: RC4 Aluminum Windows Certified After Rigorous Laboratory Testing
Friday, November 14, 2025
After several months of intensive design optimization, material analysis, and prototype construction and fabrication, we conducted tests that allowed us to introduce our new types of RC4 aluminum security windows. This achievement is the outcome of a strict multi-stage testing process, verifying every component — from frame geometry to fittings and glass composition — for strength, durability, and compliance with European safety standards.
RC4 windows
are designed to provide a very high level of security against burglary attempts by experienced burglars using professional tools. Their construction is based on new extruded aluminum profiles for particularly demanding applications.
The tests were performed in an accredited testing laboratory, using the full toolset defined by the EN 1630 testing standard, including crowbars, wedges, drills, and hammers. The tests lasted several days and included both static tests and simulated real-life intrusion attempts with advanced manual tools.
The positive test report obtained classifies the windows as RC4 in accordance with the EN 1627:2021-11 standard, confirming that our designs can effectively resist intensive and prolonged forced entry attempts, protecting the building's interior even from experienced burglars equipped with professional tools.
Key performance factors include:
· modern reinforced aluminum profiles with optimized cross-sections,
· laminated glazing P6B-class according to EN 356 standard
· high-performance anti-burglary hardware,
· precise fabrication and assembly technologies
Completing the tests with positive results is not only formal confirmation of the product's quality, but also proof of the effectiveness of our engineering philosophy — focused on measurable, verifiable security.
The introduction of new types of RC4 aluminum windows to our offering opens up new possibilities for the use of our products – intended for investors, architects, and general contractors implementing projects where the highest level of burglary protection is essential.
