Composite windows and doors

When referred to windows and doors, “Composite” is a generic term which indicates that the units combine the attractive look and effective insulation of a timber window inside, but have aluminium on the exterior for easier maintenance and durability.

“Composite windows” and “alu-clad widows” are often used interchangeably, but it’s important to know that not all composite windows and doors are the same.

With sash and mainframe produced primarily from timber and only faced with aluminium, an aluminium clad window is essentially a timber window, where the external frame is covered with a lay of aluminium for protection.

True composite window systems instead, feature an independent aluminium sash on one side and timber mainframe on the other. In this case, the individual materials are easily distinguishable within the “true” composite structure and are bond together to provide unique properties and excellent performance.

Aluminium is supremely strong and durable and is highly resistant to corrosion, capable of standing up to the outside elements. While PVC windows may require periodic replacement, you can rest assured that composite window systems will keep on working, providing style and performance without compromise.

VELFAC composite windows are designed to last, and have a lifespan of minimum 40 years, with no repainted needed for the lifetime of the operation. The external aluminium frame of VELFAC composite windows is powder coated.
