System information

VELFAC Classic is designed to provide high performance and a traditional window design. Modern requirements for energy, noise reduction, security and weather resisting performance are combined with traditional detailing.

VELFAC Classic wood/aluminium is a traditional styled window with low-maintenance exterior, which needs washing once or twice per year – no need for re-painting.

The range consists of windows and patio doors in wood/aluminium and is rich in traditional details such as external slim-line barrel hinges for sidehung openers, slim and profiled glazing bars, and moulded internal wood frames.

Windows can be designed to match styles of traditional or older building aesthetics e.g. cottage, farmhouse, mansion etc., and are suitable for use in both new-build and renovation projects.

Window design

The design consists of the combination of sash profile and glazing bars.

Frame/sash profile
In VELFAC Classic wood/aluminum, the fixed and opening functions look different. The fixed consist of a slim frame profile only, while the opening functions consist of a wider frame/sash profile.
If you want the same looks throughout the project, a fixed casement can be supplied in stead of the fixed light.
You can also choose between 3-layer and 2-layer glazing.

Mullions and transoms
The frame can be divided with mullions and transoms. This gives the option of different opening functions in the same element.

Glazing bars
Each sash can be divided with glazing bars to achieve a specific design expression. VELFAC Classic wood/aluminium is available with horizontal, vertical, cross and T-shaped glazing bars.

Colours, materials and surface finish

VELFAC Classic wood/aluminium windows and doors are made of hard-wearing materials that require a minimum of maintenance.

We are careful when selecting suppliers and when specifying materials. We put great effort into processing and surface treatment. These are all cornerstones of a quality product.

The external aluminium profiles are polyester powder coated. The surface reminiscent of paint on a car.

For frames, mullions and transoms we use FSC®-certified pine.

The surface treatment of wood and aluminium are described below.

Shaped and curved elements

VELFAC also manufactures windows and doors with oblique angles and curved heads, and completely round windows.

Some shapes can be produced with opening sashes - others only as fixed lights.

For shaped elements there are a few structural rules that must be observed - contact VELFAC for more information.

23mm glazing bars are not available in shaped element sloping more than 45°.
