The Crealco Swift 38 is a heavy-duty casement window system with a 38 mm outer frame, suitable for residential and commercial projects. It supports top-hung and side-hung configurations and allows for larger opening vents than smaller casement systems.

Designed for strength and weather resistance, Swift 38 can accommodate single or double glazing and optional security features. It is commonly specified where improved performance, durability, and flexible window sizing are required.
