VELFAC Ribo wood

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

Frame/sash profile
In VELFAC Ribo wood, 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 Ribo wood is available with horizontal, vertical and cross glazing bars.

VELFAC Ribo wood windows and casement 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.

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

The surface treatment of wood is described below.

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.

Here you find the min./max. sizes for all opening functions in VELFAC Ribo windows and patio doors.
