Unlike ordinary windows, UPVC profile systems are designed with multi-chamber profiles that contain dedicated cavities. Within these cavities, galvanized steel reinforcements 🛠️—typically between 1.5 mm to 3 mm thick—can be inserted. This isn’t just a minor upgrade; it’s what gives UPVC windows their exceptional structural strength.
The thickness of the steel and the overall profile series can be customized based on:
– 📍 Local wind load requirements
– 🏢 Building height
– 📏 Window size and style
This means whether you’re on the 5th floor or the 50th, your windows can be engineered to meet specific performance standards.
For high-rise buildings, two window styles are often recommended for superior wind resistance:
– Large-section sliding windows
– Inward-opening casement windows
When properly reinforced, these windows can achieve a wind pressure resistance class of Grade 2 or higher—meaning they remain stable, secure, and airtight even under strong wind conditions.
So, if you’re looking for windows that don’t rattle, leak, or bend when the wind picks up, UPVC profile with steel reinforcement offers a smart, safe, and scientifically backed solution 🌬️✅.
