This 50mm frame casement window adopts a thicker 1.8mm aluminum profile. Compared with the conventional 1.2mm version, its overall structural strength is increased by 50%. The reinforced profile effectively resists deformation and sagging, with far better wind resistance and load-bearing capacity. It features multi-chamber & triple sealing design, delivering superior airtight, waterproof and sound insulation performance. Matched with heavy-duty anti-corrosion hardware, it ensures stable operation and an extended service life. Perfect for villas, high-rise buildings and large commercial projects.
